| 00:02 | Uh huh. Yeah. So um don't want to talk about about the |
|
| 00:16 | any questions otherwise on Mp or anything before I. Yeah. Yeah but |
|
| 00:26 | Yeah so well a lot of today I just really want a slice of |
|
| 00:37 | to prospects are and most of the on demo and welcome back projects. |
|
| 00:46 | what about that song? This essentially wow I'm prepared for that sector. |
|
| 00:53 | in terms of the websites at that in a small crime reasons like checking |
|
| 01:02 | so um and a lot of other today is about What's known as one |
|
| 01:13 | Communication in one way or another and about something on this virtual apologists. |
|
| 01:21 | we'll see how far we get. . Uh First thing then um that's |
|
| 01:30 | little bit more of a slide showing idea behind the Sandra C that communication |
|
| 01:40 | they talked about. So just one named the science. The best showing |
|
| 01:46 | are the fact that things are in not synchronized in the sense that um |
|
| 01:55 | and receive can be posted by the processes that can give a tax on |
|
| 02:02 | personally assignment showing that in this case perceiving process. I got to the |
|
| 02:10 | to they seem something before the sending did and in this case sending at |
|
| 02:17 | point also them uh they're both supposed send him and the buffering and so |
|
| 02:25 | a little part of the whole transaction the NPR communication like this takes care |
|
| 02:33 | they're buffering and moving the needle from standing process to the receiving process and |
|
| 02:41 | it stuck into the memory of the process. So kept this line is |
|
| 02:49 | to just show that there's a bunch independent processes are involved in doing this |
|
| 02:55 | . See in the standard send receipt of models. So uh in order |
|
| 03:09 | try to so that means this transaction not uh completely without both sending and |
|
| 03:17 | process is being involved and when it is depends on the progress that the |
|
| 03:23 | processes makes him the completion of the . It's a function of both the |
|
| 03:30 | and receiver. Yeah. And sometimes not necessarily what you want because if |
|
| 03:40 | sending process in this case I wouldn't depend on the outcome of this transaction |
|
| 03:48 | order to proceed and do something And in particular supporting some, it |
|
| 03:56 | down the sending process in terms of it can do. So that farmers |
|
| 04:01 | up with this notion on one side communication And it's strike two kind of |
|
| 04:10 | the illusion other things ahead. Like if you are reading or writing towards |
|
| 04:16 | local memory in this result. And it's important to remember that N. |
|
| 04:24 | . I again was designed for communication independent processes that they're also advocated on |
|
| 04:34 | processors or notes in the cluster. So that means they're totally independent |
|
| 04:42 | Normally there is no chad and in they're always only knows about several commandment |
|
| 04:49 | know about any of. So one the step and this one is and |
|
| 04:58 | the FBI folks came up but this of trying to make part of their |
|
| 05:08 | visible to other processes. So that that memory then there have been declared |
|
| 05:17 | through a little bit that that happens this process can Then another five or |
|
| 05:24 | Yeah, I know that part of memory is accessible to other processes so |
|
| 05:34 | one we call and I guess or to call it the global address space |
|
| 05:38 | that each process still has his private . Yes. And then other parts |
|
| 05:47 | the memory or at the space send to the factory visible. So other |
|
| 05:54 | can be 600 so and this is kind of illustrate their you know that |
|
| 06:04 | can retreat In this case process one and Bridget data from and one of |
|
| 06:13 | other rights that give an example of process to and I just put this |
|
| 06:19 | in the time so it's kind of not the same but it's kind of |
|
| 06:26 | concept to this unified memory that we about trump's it'll be nice to see |
|
| 06:32 | distinct memory that physically memories either on CPU more on this. See if |
|
| 06:39 | and it's not sort of the same or the same address space natively because |
|
| 06:48 | sitting on opposite side of this besides that takes But by pairing these notions |
|
| 06:56 | unified memory, it allows the low routine operating system around that system. |
|
| 07:03 | about both address bases and the program I cannot think of Yeah, Combined |
|
| 07:11 | memories as if they were one part an address based on that the conference |
|
| 07:17 | figure out exactly what to do and not the local memory reference like a |
|
| 07:21 | store operations but it's actually has data to remove over an I. O |
|
| 07:28 | . There are different mechanisms but it the programmer not to have the project |
|
| 07:33 | but I'm so different about this Mhm. So that means that in |
|
| 07:41 | the communication that's true in this case process posted son and then eventually the |
|
| 07:48 | sided part of empty takes care of and basket deposit whatever the process wanted |
|
| 07:56 | send in the memory or their seeding . So and part of it the |
|
| 08:06 | necessary was to try to improve performance one of the aspects in that |
|
| 08:14 | Oh ascend. And that's the right to another process or sending data to |
|
| 08:19 | process can be simply done by this process. As long as that process |
|
| 08:26 | access to the memory of the receiving . So it doesn't need to wait |
|
| 08:33 | the in this case process. Want get to the point where we received |
|
| 08:39 | statement is full, it is okay in the receiving process. Uh huh |
|
| 08:47 | huh. And so typically it is general notion is remote memory access. |
|
| 08:55 | Instead of talking about one sided people often talk about the general concept |
|
| 09:02 | the remote memory actions but that required one sided. That mechanism in order |
|
| 09:08 | it to be usable promises just next few things that so in terms of |
|
| 09:17 | conveniences of using this and as well potential code are using This one side |
|
| 09:23 | communication at some point. So you to come and because we're one of |
|
| 09:33 | things that play there over the summer I can tell you what the outcome |
|
| 09:38 | but what can I do for a bit and this dependence so many cases |
|
| 09:47 | sand received protocol. This kind of in some sense it's about these areas |
|
| 09:55 | you know get some put about can put in some additional burden on the |
|
| 10:02 | . And because in many cases there no employed synchronization and get some puts |
|
| 10:07 | program semantics requires a certain order of . Then it's up to the program |
|
| 10:13 | ensure that actually true. Um so little bit now I'll have to grateful |
|
| 10:26 | the global or public or shared memory the notes. Um so the FBI |
|
| 10:34 | has a few different commands to do . So uh I want to talk |
|
| 10:46 | these fours. So the general term this shared memory across Notes. What |
|
| 10:57 | call the global public but it's shared no as that's nothing to do with |
|
| 11:03 | and Windows but the FBI calls call window. So it's just um memories |
|
| 11:14 | in each nose that is visible to notes or processes such as say |
|
| 11:23 | So that means processes that form some of a group. I think we'll |
|
| 11:35 | about it. And so you have last time that can define collection processes |
|
| 11:42 | to form a group. And then group is also in one of these |
|
| 11:49 | . Is that some of the context allows processes to communicate with each |
|
| 11:56 | So these processes that are in the and then uh each one define what |
|
| 12:04 | of such a space. It allows processes to see. And the then |
|
| 12:11 | use this name of the window as handle. So all the processes that |
|
| 12:17 | to chair part of their memory used same cancel. So that's the thing |
|
| 12:22 | the funds you get to this global against space. And then there are |
|
| 12:30 | few different words are listed on this . That guy um manages physical level |
|
| 12:38 | this place. So it's great alligators great dynamic and allocate shared but slightly |
|
| 12:46 | properties as its chosen this slide and Tony great parties you already have allocated |
|
| 12:57 | and just want to make it then available on the process point of view |
|
| 13:05 | they allocate. That's both things at advocates and makes things available. Other |
|
| 13:12 | and then there's some other trickery of to create to handle the create dynamic |
|
| 13:17 | then with you can then attach and manual regions to the sandals, dynamical |
|
| 13:27 | then there's one except for if you things within and out champ So I |
|
| 13:33 | some examples I guess not tell a bit more in detail but there are |
|
| 13:38 | are but it's essentially the same thing and so many contacts you take appointed |
|
| 13:47 | starting address for a memory region and you define the memory region that is |
|
| 13:58 | interest in a different context. And you define the memory region is by |
|
| 14:05 | account and the data type so you f b I can figure out how |
|
| 14:10 | friendly is that that represented something in of floating points, you know four |
|
| 14:17 | for a single position data type. fights for double position data types, |
|
| 14:24 | type and accounts, you know how memory there is from the storm from |
|
| 14:30 | is the case and then uh you the window name as I said the |
|
| 14:36 | for this uh collection about it in different processes and then they communicated in |
|
| 14:44 | the processors Yes, pretty much. there is also disappointments. That's the |
|
| 14:55 | a enables you to awesome So I'm to do a strike in terms of |
|
| 15:03 | uh the memory is uh collect or . So it's displacement differently. |
|
| 15:13 | And then there's the info thing that a lot of different things. I'm |
|
| 15:17 | going to get into any details but various ways to try um tell NPR |
|
| 15:26 | yes. Yeah. Global address space , can be manager should be managed |
|
| 15:32 | they accept control a little bit how level of optimization in terms of access |
|
| 15:40 | the run consistent. And then and I was very simple example, uh |
|
| 15:52 | uh, when those crates statement on side memories will be allocated and great |
|
| 16:04 | that is visible. Two other processes an end conditions on access to that |
|
| 16:18 | communicators. Np I can't work with . Good night. Yeah, Jonathan's |
|
| 16:28 | previous particularly remarkable and like that and the alligator is similar in the sense |
|
| 16:41 | up that also in the includes the of memory I'm supposed to just making |
|
| 16:46 | accessible and then there's christian out of example where is about memory is not |
|
| 16:54 | allocated on this case. That happens well the same for us. And |
|
| 17:04 | then there's also this dynamic examples to that that's the case. The handles |
|
| 17:09 | hard to access things and uh huh in this example here then it's absolutely |
|
| 17:19 | actually memory chunks to this that respect use the same handle throughout. Can |
|
| 17:31 | change whatever you want to be accessible that window. Yeah. So this |
|
| 17:45 | just some details um, so any or comments you or anyone else, |
|
| 18:01 | those exclusively that but also not to that these bones their electoral statements, |
|
| 18:09 | buy all the conversations Yes. The does not call it any of the |
|
| 18:15 | that they don't know about every Not possible. Yes. So and |
|
| 18:24 | comes back to yes. The fundamentals terms of NPR uh, only the |
|
| 18:35 | has a global picture of what's supposed can happen. So a program I |
|
| 18:42 | number of processes to share something. has to be explicitly stated for each |
|
| 18:48 | and they have to they need to stable from him. one of these |
|
| 18:53 | that should have Yeah, again, they are not necessarily synchronized. So |
|
| 19:00 | doesn't mean that these processes execute this at the same time but before they |
|
| 19:07 | access it, it has to be by the different processes. Right? |
|
| 19:14 | is this local so certainly not Good. He's asking where is the |
|
| 19:31 | the accessible look at it where it's of the local address space in this |
|
| 19:41 | . This process has its home. have the process on different notes. |
|
| 19:50 | physical memory then is in different There's so it's just a question of |
|
| 20:00 | some sense, largely collected. Collective . Each. What part of the |
|
| 20:07 | memory what part of but the starting finish address is can be totally different |
|
| 20:13 | each one of the processes. So no particular six. There's a top |
|
| 20:19 | bottom of memory. Something in a in memory that you define? We |
|
| 20:25 | that the pointed to the starving address the trunk or substrate collection of |
|
| 20:34 | But do you want to be in uh remotely visible at this place Because |
|
| 20:44 | data types is in this thing you have the right data types. So |
|
| 20:48 | means you can not just continuous box memory but point into some studies also |
|
| 20:58 | structure in so if we have to other stuff. Thank you. Well |
|
| 21:15 | so there in telling the story. . So I'm not sure if I |
|
| 21:27 | but just give me an example. Yeah, you know process zero may |
|
| 21:35 | it is just awesome. One variable all yes fights or work. That |
|
| 21:44 | location 100 is what I want to and the other gun do location |
|
| 21:53 | So there's a totally different remote Um, I don't know it |
|
| 22:03 | but I believe there is no um allows you to. I believe so |
|
| 22:14 | correct. And what I believe the of the window need not to be |
|
| 22:20 | same on all the processes in which they're not done. It's up to |
|
| 22:26 | program and to make sure that things go wrong. Well, So what |
|
| 22:31 | saying one man just one fight And process maybe $100. So they may |
|
| 22:40 | different addresses space but since then the , what if that's what you do |
|
| 22:50 | So is no copying involved. It's saying that like when you have a |
|
| 22:59 | computer you have a single other space start from. As you always keep |
|
| 23:05 | of the memory space for itself. it doesn't look too everything. And |
|
| 23:09 | the usable address space start from some and it goes on to history and |
|
| 23:13 | the um and then where where are misallocated that that's just what where the |
|
| 23:22 | ends up is the function of what decided. Uh map things into the |
|
| 23:31 | objects based on their members and that's what then the addresses gets computed. |
|
| 23:40 | when you do a clothing store from components of this generation, it's known |
|
| 23:47 | ? That very relief san Francisco. the second round process process of product |
|
| 24:00 | if he wants us the entire Yeah. So it's you know, |
|
| 24:05 | code is symbolic. So it gets brocade from this process. And then |
|
| 24:16 | compound in combination with the runtime system out word does they lived in this |
|
| 24:25 | ? That's fine. Yeah, but have to make sure them that it |
|
| 24:33 | . Mhm. That it is but in the window that you want |
|
| 24:40 | Sure. So if who processes are than the fact is a fact, |
|
| 24:50 | know, access. It is. , it's a difficult fighting. |
|
| 24:59 | Uh the network is the transport but worst on the runtime system uh tells |
|
| 25:08 | network what to do. Yeah. the members are located on and they |
|
| 25:20 | sometimes also about enforcement. So if have a process to wants to send |
|
| 25:26 | data, I should put some data this one. Yes we are on |
|
| 25:32 | division. We tell me network Okay. And then the NPR interview |
|
| 25:39 | think I just want to figure out at that point that exactly lives at |
|
| 25:43 | physical determine health. This is the not always processes on the that's why |
|
| 25:55 | tastes of the local process manager checks guarantees. Oh they're always on the |
|
| 26:05 | else that communicate with each other and to think that our side. Uh |
|
| 26:13 | . Then depending on loss the extra the call analysis target and this is |
|
| 26:22 | for example levels the internet directing. was um for brian protocol Attackers today |
|
| 26:31 | into that but somehow or other Uh hold on. The accident's hit |
|
| 26:48 | under in Vegas staring. That's so know. And just a little bit |
|
| 27:10 | concept of differences in open empty was designed for share members. It's just |
|
| 27:17 | physical memory. one who always tell about all of the memory and there's |
|
| 27:24 | always my college print edition too. store instructions that comes go we figure |
|
| 27:30 | what to Richard. You can got possessory coffee and a private store have |
|
| 27:35 | private results and everything. You can't it to see there was an additional |
|
| 27:42 | because now there's two different sample spaces to get data from one to the |
|
| 27:50 | and then no one needs to go the special express bus that has his |
|
| 27:53 | protocol how to move there between the spaces and that needs, it needs |
|
| 28:00 | be retrieved. Problems of the memory you put into the are you in |
|
| 28:07 | face moved over this? It's an line following the United Express Protocol and |
|
| 28:15 | receiving and put back so put into on the receiving Sonam. It's additional |
|
| 28:23 | is not just those stories and it gets more complicated because in addition |
|
| 28:32 | the express your protocol then the network card gets passed into the and that's |
|
| 28:40 | the Cinnabon isn't It provides a protocol goes over a bunch of wires into |
|
| 28:48 | it's complicated network it tends to have structure when it comes to faster not |
|
| 28:55 | you know the infant's adopter or as of the water is connected. Who |
|
| 29:01 | ? Well how but it tends to regular structures so that's another layer of |
|
| 29:07 | that is involved in moving data from a M month number two can process |
|
| 29:15 | another. So that all of that put into this. Uh huh. |
|
| 29:22 | terms of M. P I to FBI communications like there and hides all |
|
| 29:27 | that from the user. Uh So I think it was yeah like |
|
| 29:51 | so I'm a little bit more on of this putting yet. Yes. |
|
| 30:00 | there is this put is kind of equivalent of the scent but doesn't require |
|
| 30:08 | receive. So it's just have enough to write in the process memory even |
|
| 30:15 | it's not from the same, Know this one happened. They are in |
|
| 30:19 | same windows on the same process Thank God it's just re for a |
|
| 30:25 | dream and then there are other versions it for advancement. That's the way |
|
| 30:31 | get for the accumulates or camera put accumulate so you can sort of add |
|
| 30:37 | the destination. Um and uh and a couple of other prepared swap |
|
| 30:44 | Hope comment on. So this is picture I guess in terms of the |
|
| 30:51 | operation works well you don't have So it's not sick how much they |
|
| 30:58 | where kind of degree in terms of know the process, I want to |
|
| 31:05 | something town that laws are wow. police process, they want to write |
|
| 31:11 | and we're supposed to go. So the degree of technology, |
|
| 31:22 | Yes. This will not generate that because mhm. Just write things. |
|
| 31:31 | I feel so if we are improving , you won't have to because it's |
|
| 31:42 | right. But to get the same . So in that case the developed |
|
| 31:48 | because The two processes effectively want to data. So I wanted to put |
|
| 31:56 | else. You wanted to get something um I put in gets are the |
|
| 32:07 | independent. Uh the results are very and with all the things actually but |
|
| 32:16 | . So the senator, she's done correct order without deadlock and these and |
|
| 32:24 | . So you don't want to But if you put them both and |
|
| 32:29 | them both. Mm hmm. The in which they are executed is |
|
| 32:37 | Oh, so they have come after things has happened. They love to |
|
| 32:43 | same as the property. Hold it . So that comes back to my |
|
| 32:50 | . It puts a barn bird and the program. And to make sure |
|
| 32:58 | the outcome you want in the Mm hmm. Are they not sensitive |
|
| 33:05 | the order Or if it is sensitive mechanism in there to make sure at |
|
| 33:13 | point when you need the results, know what order the top. |
|
| 33:28 | so many things. So this is to get the operation what it |
|
| 33:32 | And the statement that's, you this is a sometimes and I have |
|
| 33:39 | example. It's on fire. So sometimes you may want to combine the |
|
| 33:52 | of the ad. Set to values then you wanted to store it in |
|
| 33:56 | of the locations Of the two Three added up. You can do |
|
| 34:02 | PSB and separated and see. And may be what you want but maybe |
|
| 34:06 | perfect defined to update days. have everyone pay for speech. |
|
| 34:15 | So sometimes you don't necessarily need it a separate thing. You just want |
|
| 34:18 | add added by some numbers and it's fine to use one of the radio |
|
| 34:26 | as the final results. We don't to override. Put that against what |
|
| 34:34 | you next. Yeah I think so are thank you. Uh So there |
|
| 34:45 | are depending upon what they want to is call the gamma rays um reduces |
|
| 34:51 | number of communication actions or it's more cot conservative in terms of memory use |
|
| 34:59 | it uses uh yet to put with that option so if it's enough and |
|
| 35:09 | this is sometimes in the parents walked is another thing here to processes involved |
|
| 35:15 | depending on the outcome here on this for now. Yeah and except for |
|
| 35:22 | and coming back to the ordering we discussed any questions on those comments have |
|
| 35:30 | comment like doing puts and gets so can the assembly process can for the |
|
| 35:38 | there will be a memory of our quality and profitability right? Not necessarily |
|
| 35:45 | . Yeah but while doing that yet has to be from telephone. Can |
|
| 35:52 | get from focus on wheels? And even if you put some dope |
|
| 35:57 | them I have to write it into global memory on the process cannot put |
|
| 36:02 | the price. Good point. So when it comes to put destination |
|
| 36:11 | to be global or share I can't you have to receive it because it's |
|
| 36:17 | else and you can it can also right into your local memory. That's |
|
| 36:21 | that's something the requesting process control. this is kind of water some already |
|
| 36:32 | responding to these questions. Uh This Children's picture instead of size again |
|
| 36:40 | shows that these two quotes on which succeeds first. Uh huh. Oh |
|
| 36:47 | it's a union. It's a cold sending process. No what is your |
|
| 36:59 | B But they may not be received the same order as the fact. |
|
| 37:09 | for sending more like possible. Yeah there are many things or even yeah |
|
| 37:17 | first is no guarantee that the operating and an effort phase potentially in one |
|
| 37:26 | . And then there's the question of work because the member of committee members |
|
| 37:32 | source and destination and they made a of different student effort. So when |
|
| 37:39 | arrive at the destination something that defending so exciting. Okay quarters. And |
|
| 37:52 | other thing is of interest also said they could get and uh I have |
|
| 38:00 | it either but when it comes to there um accumulation sickness to the same |
|
| 38:19 | farms that are order. So. And then questions on that. So |
|
| 38:42 | yeah they for this now on side not the most fantastic the organization part |
|
| 38:56 | are different ways of that's a fine or start and stuff of even events |
|
| 39:11 | which things are simple and I think easy to the gun show some pictures |
|
| 39:17 | how that happened. So that's going this basis. Defense command start this |
|
| 39:25 | in which things. Uh huh. Act in terms of the one side |
|
| 39:31 | complication. Oh yeah this property stand to the other France command within those |
|
| 39:40 | things uh have the push to get of the process participated in this point |
|
| 39:53 | this. Um So the fence and is that kind of global within the |
|
| 40:07 | of processes for which this window Obama. Huh. Another sort flexible |
|
| 40:18 | only targets focus on the windows for processes. Problem our artisans process that |
|
| 40:31 | see feminist circles so the students the on the target suppose statements that |
|
| 40:43 | Mhm. Starting weight. Yeah. hand cars look after it starts at |
|
| 40:55 | on the origins of the next and guess they can happen if they find |
|
| 41:05 | and then there's way of uh banking of preparing on the post starts |
|
| 41:13 | Mhm second forever and then there is one more that is and totally in |
|
| 41:23 | spirit of it's a memory where only process somewhat. Yes. Uh huh |
|
| 41:38 | need the participation of the process someone the other process target processes passing this |
|
| 41:49 | . Process of originally requested the active but the animal is not constipated and |
|
| 41:55 | it does fill out and unload something in central Square so there is a |
|
| 42:02 | lot of flexibility to manage uh this one size in communication actions. Thanks |
|
| 42:13 | . This is yes you get an of the flexibility in NPR uh and |
|
| 42:22 | I want to do it for a and it's not going to be in |
|
| 42:24 | assignments for FBI. Uh huh. this so that further discussion about this |
|
| 42:37 | under it quickly since it's kind of of more than anything else expected to |
|
| 42:45 | in this. So what next I to talk about? Yes so um |
|
| 42:57 | of these things or something. Data I was produced two years ago. |
|
| 43:05 | not but there's still climbing stand on of these past few years credit company |
|
| 43:13 | do this and religion different persons Yeah. Hold on anyone. Uh |
|
| 43:25 | Stop once like the FBI working under such a movement seeing on the political |
|
| 43:37 | to escape. Uh huh. Uh celebrate. Oh starting the access |
|
| 43:50 | llama for example access that is the science work in the right on the |
|
| 43:59 | so it steps onto the time Uh huh. Once I did. |
|
| 44:06 | right. Yeah. Oh for protecting prayer is is this item it's the |
|
| 44:18 | place. Ah two sided. Still significant factors of small my |
|
| 44:30 | The launch and massive science the science part sending the pain also you shouldn't |
|
| 44:38 | that takes it over In about two . Uh huh wow, stable and |
|
| 44:48 | other marks. Okay. Yes. moment. Oh it's it's different and |
|
| 45:02 | they need different kinds of experiments in of groups and for certainly messages. |
|
| 45:11 | I said so these networks again is honest talked about the format of an |
|
| 45:20 | message, right? They call an but this was a header that had |
|
| 45:25 | the information about source and destination and it comes to empty. I also |
|
| 45:32 | that allows the receiving process difficult if receives many messages from the same |
|
| 45:38 | Which messages system, what I'm supposed do with this. Uh and then |
|
| 45:43 | about the size of the table in to allocate memory. Oh so there |
|
| 45:51 | packet overhead and then there's a communication that then you take the empty the |
|
| 46:00 | in the center and stick to IT message that has its overhead. How |
|
| 46:07 | write and email messages and depending upon the protocol is. Um that those |
|
| 46:20 | from their behavior. Mhm. Uh different amounts of overhead and different uh |
|
| 46:31 | protocols and for these machines that was . I'm sure it was not provided |
|
| 46:40 | dance only colonization. Um So this just more of these sets of slides |
|
| 46:50 | you can look at it as the and other things. Yeah. So |
|
| 46:57 | going to talk to that's coming back Kobe example but before that the women |
|
| 47:05 | share move. It's more about I'm trying to do Uh one sided |
|
| 47:13 | that Uh huh Oh the other side for themselves basically doing these uh sense |
|
| 47:23 | computation. Yeah. Call it was with it. Is that president? |
|
| 47:32 | , let's just single there pick up down just how you obligations on both |
|
| 47:42 | friends in that case we he was framework called open marriages very similar to |
|
| 47:53 | but it only gets confused one side communications and allows you to have distributed |
|
| 48:00 | across proposed processes and the complexities where trying to deal with one was in |
|
| 48:09 | of program abilities of even though as as you've seen there's quite a few |
|
| 48:15 | calls that you need to performance. believe these one sided communication of designing |
|
| 48:22 | more than five for companies. So show program ability was to have as |
|
| 48:28 | amount of uh, as on the motorcycle And the massive obligations part basically |
|
| 48:37 | them a distributed their respective project. gonna go back to tackle all these |
|
| 48:43 | of details about it. And in of the rendering system that we were |
|
| 48:49 | to make sure that however we distribute matrices, our brains are different process |
|
| 48:57 | we should use the one sided computations the ascendant received, they have a |
|
| 49:05 | amount of relays in terms of synchronization . You think about having millions of |
|
| 49:13 | on a constant and those small delays not big ridiculous seriously market in that |
|
| 49:21 | we used is one side of communications women that are running already. I'll |
|
| 49:25 | into beetles in such a, such way that you have to implement us |
|
| 49:30 | amount of super visitation policy in the and still get the characters. So |
|
| 49:38 | was more portrayal that thing out. . That nature systems of that programmer |
|
| 49:44 | have to worry about any interest you understand can access the matrix just like |
|
| 49:49 | models. Hi jay Dixon. But run down what happens these data movement |
|
| 49:57 | and we know that pitch matrix um blog decides on which process and then |
|
| 50:04 | having complications process the first performance. you did a big difference in terms |
|
| 50:18 | . Right. Yes. Right. how they uh I didn't get tested |
|
| 50:30 | I only worked with general burgers. bubble machines of them promise to |
|
| 50:40 | Residents are still believe people alive. a random favor. Oh But in |
|
| 50:47 | Madou Observer was more than 10 Yes . Speaking. Right come back. |
|
| 51:00 | . Oh okay. And probably one No but the difference different ways of |
|
| 51:09 | it. Oh Oh it was almost something Background 65 600 Yes we do |
|
| 51:20 | . It was about how you perform so one bottleneck that I found out |
|
| 51:27 | was similar to what you guys have . Are there uh Iran memory within |
|
| 51:32 | experiments when people demonstrated Uh data transfers the memory of the old one is |
|
| 51:40 | that was superb performance by this and transport that's it was one of the |
|
| 51:45 | next that I am sorry I just communications not realizing that under the hood |
|
| 51:52 | communications are so the solution I was simple that agreement. It was the |
|
| 51:59 | copies. That's right. That they're to convenience but and then send it |
|
| 52:04 | across the I. O channels back concert. Uh so there is about |
|
| 52:10 | times ask me that there was All right, uh huh. So |
|
| 52:19 | point is it's not just 100% many . It's it's best that making it |
|
| 52:25 | or impossible. So right. That's just to get the scale. What's |
|
| 52:34 | impact on me that it's not small that's one of the reasons that we |
|
| 52:40 | talking about. It's about cardio the data sets that the signs of |
|
| 52:47 | that is quite a matter is growing that you're doing FBI. So you're |
|
| 52:54 | of scaling the multiple loans and you have that much work otherwise. The |
|
| 53:00 | of the ramifications questions for you. that philosophy, get the real working |
|
| 53:16 | example of this case is over understandable for the record should be potentially support |
|
| 53:31 | of these boats are generally anyway, coming back to jacoby that it is |
|
| 53:38 | some point in the past now in context of noon. So I mean |
|
| 53:44 | problem this takes to the, to examples of stuff that's the regular mess |
|
| 53:54 | that they want to solve this equation uh thinking on temperature or pressure or |
|
| 54:01 | like that in the square. So order to do then eh cluster setting |
|
| 54:11 | you do a core of uh the and something something that each one of |
|
| 54:18 | processes that the source. That's all processes can be a little bit something |
|
| 54:30 | and then it was still supposed treated a one problem. So one thing |
|
| 54:37 | high potential. That's all right. , that's a nice it's just uh |
|
| 54:47 | on that. Right? But apart in the notes here on the boundary |
|
| 54:54 | don't have a body. Uh The boss's saw that happens in |
|
| 55:02 | The data from the north. Mhm. It's not on here uh |
|
| 55:18 | to go the boundary data. So that to do something this song. |
|
| 55:27 | about that already been bothered remarks and uh you know just this is Oklahoma |
|
| 55:38 | up in the government from human dating fellow and just you know this process |
|
| 55:47 | order to get the exchange of So that's again my exchange data and |
|
| 55:52 | can do it by send receive so can do foods that gets So this |
|
| 55:59 | is using put and gaps. So is best to showing that what the |
|
| 56:05 | principles you need to advocate. This something mean but often out of the |
|
| 56:13 | you need to receive a call the is and the simple where you're that |
|
| 56:20 | be remembered for. So so I that I'm putting on my sword officers |
|
| 56:30 | last member of parliament about please. simplistic. It's just allocation of memory |
|
| 56:35 | what you want to do. And have regular access stuff You don't put |
|
| 56:42 | society separate the rain expected. It be easy. And his reference in |
|
| 56:51 | of record somewhere else. Younger Yes. And it's sort of the |
|
| 57:00 | data and that computation phase is Mhm So uh so this just shows |
|
| 57:12 | what? Mhm. The green part that old? Oh yeah, so |
|
| 57:26 | goodbye and more than making the That's fine. It's all we'll be |
|
| 57:35 | as the global accessible for us and end up doing this frank saw |
|
| 57:48 | these buckets are orange and buckets for , processes. Uh the other ones |
|
| 57:56 | agreement that's uh the local owner of uh Yeah. Mhm Take another |
|
| 58:12 | So then they end up doing something this. Oh, this process. |
|
| 58:21 | is often a fun thing to write the girl. Yeah, I'm |
|
| 58:27 | opposite. So this is uh to use the get or in this case |
|
| 58:35 | the foot part and everyone can be and in fact we get the sanctions |
|
| 58:43 | in this case uh whenever the puts completed that you have the data and |
|
| 58:48 | you can do the fight consensual computation locally in each one of the |
|
| 58:54 | And so here is kind of Uh This FBI come together and uh something |
|
| 59:05 | . What 2nd phone for them but about dinner type of sausage. Not |
|
| 59:16 | this. Hopefully computation on a regular . That's a good way defining |
|
| 59:24 | NPR graphics. That regime so There is a our thoughts can do |
|
| 59:31 | and up and down vulgar. It's the next life and just to keep |
|
| 59:42 | Uh huh. Where we follow the and another department. And you have |
|
| 59:51 | basically for the computation part allocation In nice two D array where the loggers |
|
| 59:57 | included. But when it comes to communication, another complication with to figure |
|
| 60:04 | how to retrieve the border, the out of his hand, difficult through |
|
| 60:11 | race. So, so both administration use supporting and how to identify uh |
|
| 60:23 | summaries that defines the boundaries and as we talked about they got back. |
|
| 60:30 | , So it's free, yes, direction. So female, even in |
|
| 60:44 | directions, someone you want to start whole lot of straight up thoughts who |
|
| 60:53 | this element of this uh this part some doctors. So that's why actually |
|
| 61:03 | it is even for the left on other defense people die. And that's |
|
| 61:11 | happened with the idea to attack Yeah, I'm not just a better |
|
| 61:17 | and collecting these items before standing at x 1 instead of this. You |
|
| 61:26 | . This family to practice the absolute . You know, the number of |
|
| 61:32 | . But recent confrontation part will be himself Front of one element. This |
|
| 61:40 | so Oh, yes. At some . I will not a week. |
|
| 61:52 | calls. Yeah. So maybe next . So any questions on this or |
|
| 62:00 | to put fingers and also the right to do in this case some nights |
|
| 62:06 | regular access but in terms of Mhm. So this this that well |
|
| 62:24 | like the broadcast no broadcast would be um Oh and please go on sunday |
|
| 62:37 | all the other this is all get to build upon This. one says |
|
| 62:45 | process, one source, one business there's a hold up mm hmm. |
|
| 62:54 | they don't have to have them So the extent to which they after |
|
| 63:03 | humble and receive the effort. Business , get some data wow follows. |
|
| 63:17 | each transaction what what uh many all of this process. That sounds |
|
| 63:28 | 1001 time they are trying to set time in the all yes in principle |
|
| 63:38 | this statement and then it's up to the capability of the system to resolve |
|
| 63:47 | can try to get as much happened quickly as possible. But all of |
|
| 63:52 | is point to point this process. . Uh huh. So that's not |
|
| 64:14 | or uh huh uh huh. You to uh uh some biscuits do the |
|
| 64:30 | um Yes, we're in a state the product for instance the first rule |
|
| 64:43 | time column. And so I do is on the one of the scientific |
|
| 64:53 | the first gold first phone that keeps insults after the transformer. Um So |
|
| 65:03 | so in this case you modify this . This word that is going to |
|
| 65:12 | park a minute product on the first back the first column. Uh So |
|
| 65:21 | , it's eventually gone and up and opportunity for enforcement a good at |
|
| 65:29 | Next time around there was interaction The second box in the first |
|
| 65:35 | Among devise this value and other states attendance. Oh, but that's why |
|
| 65:45 | need the front and back. Big , you sort of what accumulates accumulates |
|
| 65:51 | your product in the number of of . And at the same time as |
|
| 65:57 | process embarked on the first roll And 2nd part. So this is the |
|
| 66:05 | element in the first row occupied the element, events and the part of |
|
| 66:12 | product or is it? Oh, is to do the product and my |
|
| 66:22 | and accumulate in the rock face. you said, and this takes the |
|
| 66:26 | plots, baseball and also they're fishing biking. So it's just showing |
|
| 66:37 | As I mentioned, sometimes you the , you know, forget that accumulated |
|
| 66:43 | such uh, what the result Yeah, so okay, so this |
|
| 66:52 | potentially then, well, maybe next when trump's bombing this makes responsible I |
|
| 66:59 | they're called the example and there's this bit of advice and want to use |
|
| 67:08 | simply thing as I said, one more burden on the programmer to make |
|
| 67:12 | that, um, since there is implied ordering will get some puts general |
|
| 67:20 | , but it avoids a lot of and that process is kind of operate |
|
| 67:26 | a synchronously and make the progress that make put out uh communicated now. |
|
| 67:35 | the next. I don't think And NPR used a lot of |
|
| 67:43 | Right? Uh for two reasons. is for convenience of a programmer and |
|
| 67:53 | second is for automatic processes off too process ORs so NP has this concept |
|
| 68:04 | virtue, anthropologist and you can two 2 structures basically one is uh huh |
|
| 68:14 | of whatever number of dimensions you want then they live on is what they |
|
| 68:18 | graphs. So yes. Um and was just this example infrastructures from engineering |
|
| 68:32 | amputations were um in order to be airport was driving time. That's all |
|
| 68:45 | car locks the space and are I think the supplement. Uh huh |
|
| 68:59 | of the members are used for college problem economies. Welcome to approximate. |
|
| 69:08 | huh differential equations uh continues differential operated . The tax system. Oh, |
|
| 69:20 | the truth the neighborhood commented. We yes. And all of a sudden |
|
| 69:30 | think that we just princess ha It's the accent uh respected and efforts |
|
| 69:41 | to be looking for performance and the innovative resistance. So that's why a |
|
| 69:51 | of uh all the applications, you regular demands that two and three D |
|
| 70:00 | . So that's what's very convenient. Comey example is what we do also |
|
| 70:07 | to the left neighboring east to west , north and south neighbor. So |
|
| 70:12 | you basically think of these processes like was on the side. It's a |
|
| 70:19 | dimensional grid of processes. And if have been a network that effectively coastal |
|
| 70:28 | to the emotions very well, then don't want to have an arbitrary mapping |
|
| 70:33 | these processes but they want to have mapping such that it happened to me |
|
| 70:37 | exactly the physical thing and land. that's just neighbor communication in the actual |
|
| 70:42 | as well as civil service. So that's one of the purposes of having |
|
| 70:49 | apologists. Oh that's there is. what is this petition? I think |
|
| 71:03 | you can define and uh huh This great. That's the but there's not |
|
| 71:14 | , one of the arguments that tells how many dimensions of what uh |
|
| 71:20 | I didn't create. I want to it the beans. Man FBI tried |
|
| 71:27 | figure out how the fact that the of notes that you have in the |
|
| 71:33 | processes. Thanks processes and two something is usually what you want in terms |
|
| 71:46 | . To the Bassett sees topics will in the square. You know what |
|
| 71:55 | and you want something to this so can specify, you know the length |
|
| 72:02 | the axis that you want to come the processes. That's the past. |
|
| 72:08 | him and the other figures about their there's a corresponding things. Yeah. |
|
| 72:17 | the ranch and petition grip uh report back to the plantation grid. They're |
|
| 72:29 | against them because sometimes um one wants best to do the ship left and |
|
| 72:39 | or something. Right. So the in terms of the petition and decide |
|
| 72:46 | along with dimension you want to do shift that you want to shift. |
|
| 72:54 | I'll see you for help. So the other thing you can define |
|
| 73:00 | . So here is an example of china. Yes. Um Yeah one |
|
| 73:11 | that is the original process. 100 12 fire your face. So oh |
|
| 73:22 | it's part of the sport and they a cuba B great. Uh Right |
|
| 73:32 | strap of course what you say. single single and get on. So |
|
| 73:40 | it. Each instructor and then so here. Two dimensions. This is |
|
| 73:52 | three instances instance 33 along the Uh Well now the second dimension. |
|
| 74:09 | so here the wrap around what happened stick there's a restaurant, right? |
|
| 74:21 | so it's uh and specify these things terms of, oh are you playing |
|
| 74:30 | grits? Yeah. So I guess example as I said it and then |
|
| 74:42 | I do before. So I understand big part of it. I want |
|
| 74:47 | dimensions and that's the thing or The prosecution. Uh My number is |
|
| 74:58 | with us. We'll put the dimensions the prime numbers stand back for |
|
| 75:04 | So but the deficit activities on right Advance that half of the three |
|
| 75:13 | imax dr So these are all Well we're looking for this. |
|
| 75:28 | The contract is about to practice one other factors up right smiles so it |
|
| 75:37 | going to work. So I understand it's just an example when you try |
|
| 75:42 | get NPR two, did you All right. And there is some |
|
| 75:52 | examples here. Some examples to do to one of an example then Oh |
|
| 76:03 | Graph one Someone has to tell So the facts of this providence independent |
|
| 76:11 | of the policy that so if you have a regular kind of underlying best |
|
| 76:17 | have a problem for a graph like . So you have a relationship |
|
| 76:24 | Maybe I'm doing it many times to the aircraft. And so NPR that |
|
| 76:31 | of this way for them. Uh . Doctors say. So we get |
|
| 76:41 | know them to God to specify in a half degrees and then you specify |
|
| 76:48 | target for the outcome. So in case uh zero. And this |
|
| 76:55 | Uh Huh. I don't get it land on no. Up with the |
|
| 77:06 | process one and 3 edges coming That's it. He's waiting for you |
|
| 77:15 | but eventually built the structure. So mechanism this time the only thing you |
|
| 77:23 | to that's it sacrificing animals and you hurt yourself where you coming from several |
|
| 77:32 | yesterday. Yes and then S. . I contracted this best job once |
|
| 77:40 | knows the structure the map it onto actual physical network that connects in order |
|
| 77:47 | order to try to also they make communication as efficient as possible. And |
|
| 77:54 | the program americans use. No, is after station the right moment, |
|
| 78:04 | like with relationships and report in the and residents of so. So it |
|
| 78:13 | sometimes it was sort of conceptual basis the cold, but it also gives |
|
| 78:19 | to NPR in their ransom system for to map things onto the physical. |
|
| 78:27 | , no part. And we have take my time. Well, |
|
| 78:36 | maybe the more human comments. Thank you. Yes. Mm |
|
| 79:00 | Um. |
|
