00:00 Mhm. Mhm Okay. Yeah, know so Okay. Today I'll talk
00:12 open sec uh same thing and make progress hopefully on that. So that's
00:28 , wow. And it's similar to , open empty as I talked
00:36 I guess two lectures ago. What also a bit different in terms of
00:44 to use it and what it can and talked about the difference in philosophy
00:53 targets behind compared to open and But its director based on a talk
01:00 a couple of directives uh And it two directives quite similar and sometimes confusing
01:12 of differences trying to make it somewhat . And that's the parallel or colonel
01:20 that you There's like two different parents I'll talk a bit specific about video
01:30 D J. Open sec compiler. is the compartment is useful. I
01:37 do anything called for the median So um this is just quick reminder
01:48 that the difference is that that said few times already that see um memory
01:59 for Gpus tend to be few times five times higher than what's typical for
02:09 processor. On the other hand, memory is more than five times
02:15 So Maximum memory attempt to be about . And the need to use the
02:21 that could be terabytes on a So, so that's memory size and
02:32 are different which is one of the parts interest pointed out I guess to
02:40 years ago. Focus on Yeah. us are the touch devices so they
02:46 connected to processor. Yeah, give pc express bus. Yeah. And
02:56 next couple of slides and I've got kind of things to try to make
03:00 really concrete things move. So just a reminder, a bit of what
03:07 talked about, talks about processors stuff processor cheers you like posing for the
03:16 . Yeah. Memory busses are distinct different from the Ohio busses and that's
03:22 we've seen this in here. That's versus C. Pictured and public education
03:32 something I think the different steps from . All right. Doctor processes
03:39 Yeah. Yeah. The difficulty of for sustaining. Huh? Uh what
03:47 that? And horses the point of that there's kind of a deep sauce
03:54 has ever And it communicates with one the wire on the surf report this
04:03 stuff and then the other expressed sockets distinct together. And it's different for
04:12 certain reports between the process of software cent starts. So they weren't when
04:21 attacks uh, you know, difficult the competition that starts in and my
04:32 processor in order sometimes all the entire . Sometimes you need perhaps things on
04:41 and there are different directors. This you need to say something from this
04:48 memory. Yeah. And uh and eventually announced that starts here and it
04:56 to be brought into the process of and the process of ability to express
05:05 . The uh the thais processor is a different circuit board on time
05:16 The first report um is expressed, with you? The third report processor
05:27 then on the circuit court of they have a few of its vision
05:32 sports. And then it just I know about this for the conversation at
05:37 point uh goes on between you. just illustrates again to take one of
05:48 relationships separate memory of course. Down fortune devices so things needs to move
06:01 uh I didn't bring a our whole you thought. But so here's one
06:11 pass it around on the suit sort connectors to the board for the processor
06:18 this case. That's tumor margins here under this cooling fan parents. Egyptian
06:24 , that is the chip, you ? Mm hmm. Right.
06:35 Yeah. Uh huh. Mhm. mom, It's kind of a Service
06:43 Circuit 4th. Haven't seen it before lot. So this is uh
06:51 Processor socket to socket here are some . And my model Margaret, that's
07:00 number of trips here for making I'm going to and then hearing.
07:06 the peace of christ So that kind reporting good finances. So this is
07:13 of memory of this processor sockets. then while it's in the circuit
07:21 hold on to these collectors. And answer that for so that they look
07:27 the data. Okay. Yeah. it's the same with a time but
07:37 a single day in chapel. Is the same as the one on stuff
07:43 No. Well yeah, yeah. principle is set up but this is
07:52 it's not the circuit board that is same as is in Skopje. So
07:58 don't so when you do this, you inform some feed it probably says
08:09 circuit for is used and then you google and find the circuit board on
08:15 web and then we will find out many memory starts they have and how
08:21 inflows from memory. How many pieces expressed thoughts. So what we have
08:27 go home? So it's money shared something. So sort here is white
08:46 provocative before. So and I think , I think there are six.
09:01 huh. Memory battles on the So good to see you. We
09:12 hear they can produce three members 300 six always most recent. Think of
09:24 put and memory channels octobers in this . So uh the circuit border Don't
09:43 to pass it down with two Oh my all right. You have
09:51 two seconds and there are differently to . So this is you um And
10:03 a connector that is being used. other songs. Oh, so the
10:09 instances of this connected, you know types of ports between the sockets um
10:14 you know the actual physical time is wires on the circuit. Who?
10:20 it's not in the package at So that goes between sort of the
10:26 squares on the board. That would a bunch of wires that carries this
10:33 for the bomb. Okay. In office. So this is how what
10:42 . Um, All of these other sockets, pirate tattoo, things like
10:50 things. Oh, the address space found to both. So, so
11:03 uh, wow, that's why open . It works because it's such an
11:12 and certainly right. So part of question. Uh, let's see what
11:20 is and reasonable anyone of the anyone in this office, any one
11:27 the memory modules that goes into any of these thoughts comfortable, but the
11:35 sign is different. That's what they the humor. So this is one
11:39 the force one that used normally connected one of the memories I was on
11:45 socket. It takes all the time associated with channels, directing, touched
11:56 . So our test european sort of the dashes off the other song.
12:06 , that's just I'm not saying because , that's the only thing that when
12:14 comes to detail and then send them some courts. It's the love of
12:21 that is shared among the board. understand it's of silica no cross
12:32 And number one and number two for yes writer. It's cool. So
12:45 fact the way that the implement that's good. I have received that that's
12:53 cash in a free pass. And just, I mean of parts that
12:57 close to 100 and then in this is it's part the network that the
13:06 communication. Of course already as a of these for you reference system instead
13:16 trying to the other. Okay, talk about the view park foot.
13:22 they did to you not further hope it goes on. He said
13:29 I see. Yeah, well things architects and around we have to go
13:39 the back of the car related. then it's a question of how they
13:46 it. They don't sometimes part of at the base part is the United
13:52 , do you so hard And I we'll talk more about that. So
14:06 while we're at it and thought I run something that Yeah, it's not
14:16 me. Trouble. Yeah. So Uh huh. And what?
14:30 these first like different type of pc ? Do not see them.
14:35 this is comfortable. Four socket We have 1, 2,
14:39 4 sockets. And in this case kind of most obvious on this,
14:45 all things up here are memory slot, memory card slot team starts
14:51 you have four. And then before with this and then there's also 44
14:58 on one side of each one of , the way it happens to be
15:02 are. And the connections that went the certitude the memories out there in
15:09 circuit force. You don't see that circuit boards tend to have quite a
15:15 layers of wiring even though they're things not just one wife so you don't
15:21 to, this was actually came out a project of a few years
15:29 So business what? Okay, so know these things looks of opportunity,
15:36 you some more intuition of how things . Oh sure. So in this
15:46 of the FBI is common for the . Yes, so that's it.
15:53 this gets the wiring on the board such that any one of these camps
15:59 doctors can reach, you know, of the this is our if you
16:04 it. Um so these are you need to and the D.
16:10 . That's a standard protocol B. . I. And the way these
16:14 look these are probably something that are , it's fine And this may be
16:20 only eight. It's fun. So comes to they want to go back
16:26 the first round and you look at specs for and the interesting elections since
16:32 has A few times 16, 2 eight and some of the four so
16:39 . So catalysts for number of this has on the human cycle. And
16:46 usually for this express particularly sorry, you need a is pretending to have
16:53 is 165 data path But for some devices that may be OK Susan eight
17:00 like the video video card, It be a difference of the data rate
17:06 which ones you use because again the of wires that comes out of this
17:12 is for the limitation with superior and there is one of them that part
17:17 water but I want some other ones that. Mm hmm uh huh That's
17:24 1, 1 big block here is of all the sites. So it's
17:31 mixture depending on the device. So you don't need so as I
17:37 you have a limited number of wires can put and this little footprints and
17:43 a question then if you want parallel many, I wouldn't want many different
17:48 . They don't want to have things up more various than it's actually
17:53 So that's what you get more channels a few words Pittsburgh channel and that's
18:00 trade off. So if you look the conservative boards we will find out
18:03 some of them have The only time starts And some of them have a
18:09 and many more times eight times 4 it depends what the board is supposed
18:14 be good. The only 16 and like is higher back, wow.
18:26 see I don't remember, I have so the pcr expressed but is a
18:37 even that 16 gets right. It's lot slower than the number it's about
18:44 or that the clock rates uh huh new convert I think it is the
19:02 stuff um then I started to talk it. So yes, no class
19:09 reason. Um so and the higher corporate, the more power and energy
19:23 takes to drive in particular when you things on the circuit board I suppose
19:30 a single piece of silicon. So that's why it's kind of an issue
19:34 drive up top grades when they're Mm hmm. So yeah, sometimes
19:58 it's correct. Okay. It's a bit sore but not much older than
20:04 about compromise on taxes. It's not . But remember the channels up to
20:12 it's going to take one word at time. Whereas that that's all I
20:20 China don't take this 10 30 There is one began because limitation is
20:26 working Instead of having four different channels 16 1. They would only get
20:32 at 64. So that's okay. could potentially use that difficulty. Industry
20:37 decided more channels as president one. . That's the train because um again
20:50 whole times about this one. So , that's the case at all.
20:59 C used to that a statement for fellowship support despite. So that's 504
21:08 just for the data Send them in and clock a lot of the 17
21:15 whole concept remember and then we need get the only answer. Oh and
21:23 it's probably good improvements of the topic only gets the 2000. That's the
21:32 , the hardest part for you. in some ways the facility because I
21:44 he's a silicon and induction process early do this. Standard processor you're basically
21:54 that have that sense of in collectors the end. And so we can
22:03 in software raised from the dead inside to be specific on that where Only
22:16 on in front of 500,000. So have about 100 millimeter centimeter and a
22:25 . That is the fact that the of what and the ring is it
22:31 because from the gasoline this package that is in and this activity you need
22:40 you know, and chemical strength early buyers, uh, events are too
22:50 . And so that doesn't work for long time and a human error or
22:56 and the bumps it looks of course that's so you don't need to have
23:01 that sticks up because then you will the level then you're probably so that's
23:11 . It's very hard because you yeah, it's where to work with
23:16 terms of putting catheters and stuff you to have the edge to work with
23:22 is best foot square room. What of in terms of, you can
23:28 that from the socket they can use do things for them. So,
23:34 it's not so easy to be Talk about funny. I think I
23:39 how to connect concession some of the that you want to face. And
23:48 why communication data, motion is the because you got the bottom that's essentially
23:57 dimensionality. Both of thanks. What it was tracked and a bit it's
24:02 carrot kart and that's sometimes forgotten. we talked a little bit our chips
24:11 ? So So some of them are like 400 lots or something more and
24:22 not operates based around one ball. that means it's time £400. Anyone
24:35 about the household currents and difficult. you. four wires down on the
24:44 . So they were you know very them to the single water.
24:50 And the virus inside too. The way to get married. But still
24:59 it has been told The virus on two x 2 cm square. You
25:06 there is about a 100 there's something think about challenges in terms of designing
25:16 because it turns out nowadays a lot the china is again I thought about
25:22 energy efficiency you know for all kinds cost trees and environmental reasons. But
25:27 the silicon designer is the question of for the level of power and it
25:33 the drive of transistors and models. the juices before chip design.
25:51 normal of course. Okay. Yeah. Uh huh. Okay.
26:09 some perspective on what will it or under that put themselves what's important?
26:20 necessarily wants things of fabrication and you use it the silence of the comes
26:34 from there. All right. All . So again this what's the program
26:41 and talked about. Uh huh We off shots. The versions of Yes
26:51 talk about is in the context of test devices that is typical intense data
26:58 servers. One is not the model mobile devices where you have to use
27:04 on the same piece of silicon. , but I think we are talking
27:10 this community to go over this you and they are not standard devices that
27:18 actually need conventional processor as the host so program and data that sort and
27:27 was uh Yes and the first interesting they are programmed at both on the
27:36 before you can do in advance and use of conservation and when it's all
27:43 and done the next time. So kind of the paradigm things start with
27:53 holes cold and dead animals to the . This is cool. And and
28:01 device is done with what has to Then data gets return one way or
28:06 to the hopes. Uh and I this was just recall from earlier in
28:13 process of actually has kept some numbers I already mentioned that yes this is
28:18 night a couple of things stand for open it to see standard couple of
28:27 for that. I'm fearful can be fighter. That's terrible. And uh
28:41 then being their father jesus scene Answing and use principle two choices for working
28:53 , I think that it used um also to introduce uh the use of
29:00 two choices but the choices now media that case it used to be that
29:06 can't find out of this C. Was one was the compiler company together
29:13 another company company and in the tournament started development open it to be um
29:24 also beginning, they also supported their but constant video purchased this combined company
29:32 the support for the computing keep use it in these so in a
29:41 so it's also mentioned a bit of mess in terms of things not being
29:48 universal and affordable in that works with and Media Gpus that intensity forced to
29:57 with the tools of together, you , the industry sometimes they're struggling to
30:05 to figure out how to make it with open MPI That is one framework
30:11 is supported by or the compiler So, standard apron ec is also
30:16 standard um yeah, historically ended up ah attractions that somewhere but certainly abuse
30:31 . It's not universal. Okay, these directives of someone is first directed
30:40 about is that they have to what's are seeing and Uh huh. And
30:50 so here's the first one a bit and that's the A C.
30:55 That is based or accelerated, modify but in fact they stand out when
31:03 want something for a the touch one of the draft uses AC.
31:10 . That's called for the device. can actually have different options for that
31:20 . Uh That defines rhetorical absolutely wanted but by the thought that you don't
31:29 anything the HTC Minister please generally called the attached device and its device attached
31:40 the processor on which the combination I think that's so and similar to
31:54 and please And uh parallel. This some of the same way. Uh
32:04 . That's the garbage here, gangs instead of friends. Um So that's
32:11 Mhm. The difference has been unclear this level of gang traveler. This
32:20 . All of that moment probably replicate same thing as opposed to the current
32:26 and finance fee. It didn't do the future and distract against school ever
32:31 . And in that case went to same this is every guy executed.
32:38 problems are supposed to want that they to no right to take composition,
32:44 some work for it. The final that could open in 2000-4. Check
32:52 . Um And this is just So the same thing that I do
33:03 based on the cult so watch and the work sharing and it is too
33:13 open empty. There was therefore I told the comparator I want this
33:18 the document beds in that case from basic dr respect us at all.
33:29 . Song has uh huh and it the region 15 and then you don't
33:40 huh. Yes. Works. And so it's important it's kind of analogous
33:49 what you're familiar with. Broken Yeah. And within the government that
33:58 forget to mention jumping. Um so , so the one partner is um
34:20 are more almost as we did The construction opening tee an implicit barrier.
34:33 all the different threats, synchronize at end of the four little before moving
34:37 unless you have no weight in the threats completely. But points for thursday
34:44 kind of the opposite and help me . The 4th is still sinking down
34:50 little on that. You have a to sacrifice. The report is just
35:00 . And that's that is for the construct the parallel region is different.
35:05 close the same, but not. in this case if you do
35:13 you know, construct 1st Caroline's but at least no. And or
35:24 gets divided up optimal. Thanks. , generous workers as they call
35:32 Yeah, he's back. Yeah. and what? Yes. So this
35:47 the one where well uh huh in . Strong man. So uh so
36:02 is kind of a safe programming because what it is set up.
36:15 that's again uh different from other You actually we thought news in the
36:25 parallel region, there's no guarantee that let it right, executing the first
36:33 of. uh huh finishes before anything the second. They're not necessarily so
36:41 . What happens the first to start second ST a brilliant because,
36:50 good point in the roof constant and think I have examples to contact.
37:03 this is what I said just without uh, it seems that there is
37:10 long story bosses school. Okay. is the highest level of earliest um
37:28 the structure of the DP new whether it's a, B or C
37:36 somebody else's start at the bottom. are these Better units are the units
37:44 as one instruction and multiple constant unions just the same, execute the same
37:52 . Those are replicated a bunch of into group of units you're standing multi
38:03 terms of, I mean, I know what their work was not to
38:09 . And then these training multi process with a bunch of activities inside them
38:15 again replicated on the shift in order get these thousands of Functional some special
38:21 levels of grouping. That sort of is the highest level. Amanda house
38:29 uh mm hmm streaming multi process the that fits basically have the functions.
38:40 , uh, so the workers come the workers for example, otherwise who
38:50 stopping the same. Oh, they notice but sculpted process that was an
39:06 . Oh yes. Uh huh. . Well as well, but I
39:16 it's not a lot. I think , he's like, oh, it's
39:33 thanks fine. The next item That's one of the kind of stuff
39:40 he has the same kind of reduction that you have an mp in most
39:45 language support some form of reduction So now I'm talking about this carnivore
39:56 then questions so far for comments. , Oh, okay. Uh
40:09 So why is the first a All right. Similar cardinals girl,
40:21 sure how happened in history that I'm sure that the openness to see me
40:32 fact only had kernels directors at the because the target of the group that
40:39 first Informations of open is the ceo secondary code for use big star
40:46 It's used, you know, So, and in that case the
40:53 is Cornell is I think piece of that was supposed to work on the
41:02 at that time. The new memory very small or a cold results come
41:13 the colonel other piece of cold and Children. And because another his work
41:19 the work. So the cardinal thank the, the science believe more than
41:28 that was kind of the concept that sense for generating course of youth with
41:35 notion of the horse. Is there things over is for me to do
41:40 for me. Uh, now the constant positive, the people that
41:49 Oh, the development was The four and media afraid to companies. So
42:00 they were kind of expert at So the has the notion of giving
42:09 confront this freedom as possible to generate cold and not come to use to
42:16 too much. So the concept I was the the of the position transformations
42:26 the composer justice will figure it We're not producers prescribe the problem section
42:34 be But just tell this one a . Uh You'll figure it out.
42:41 there's a bit different. So that's reasons description of open C versus
42:49 one of the underlying design principles laws the computer will generated code. Don't
42:57 specify. Yes. Welcome to the . I used to think that.
43:05 huh. A real citizen to use if you simply Mhm. Do you
43:16 uh uh And they go and look up and what a lot of degrees
43:26 . Sorry. Uh But the principle when it comes to No, it's
43:36 doctor's coming up. Sure but not on his phone. But to illustrate
43:44 difference for you examples what happens in cardinals versus user just setting this
43:55 So I have you seen that? an empty happened more or less at
44:00 same time and it had open and is quite divided adoption in the
44:06 Open a C laws provided all of four companies and access students and one
44:12 machines for them. Yes. But that have other computers didn't get to
44:17 from that. So they got the somewhere open and he's not quite sure
44:23 part of the reason to try to some of the same directive construct.
44:30 piece. I guess it's an open types of companies. Open the C
44:37 because of open and feet. Um . So it's like one of the
44:50 in this thing that just the combine is work sharing is not necessary to
44:58 . That becomes the fathers both to it out. Something divide up the
45:02 for the world among others supposed to out the actual things to assist a
45:10 change. So now here's my So this is uh um uh,
45:24 information so people look at this example through is sometime by a long service
45:35 , combined to develop for about six . So, so this is kind
45:43 a simple of stature do And in case there isn't much of a difference
45:50 $500 when he wakes up like the thing and you get so uh
46:00 There are so these in both cases the people what to do with it
46:12 me. But it's the same thing compensated and there's no way history because
46:20 just in the rules and the fact that's something at the end of the
46:26 construct doesn't matter because the new bands also under the parallel region. So
46:32 gets fixed mm now. So and in the car space the compare learning
46:50 do whatever it wants to do. 1? The law Caroline is a
46:56 school. That's the electrical as The director code. Is that the
47:03 idea? And then the corporate state whatever. Uh uh huh.
47:15 okay. Does the article that gets ? This follows the will of the
47:21 . Yeah. First too. And gets paralyzed. The Avalon and expertise
47:29 this fantasies. Certainly no. yeah, the other things to activate
47:45 was one of the early excitement and to be aware of the strike or
47:55 various Nubian disease and the defense political . So I have a right.
48:02 the four time is on the top this. Yeah, confirmation order.
48:09 means the most intense. Uh, . That's a Great one. Uh
48:18 huh. Whereas the 16 that This for I equals in the 9th.
48:29 , the first thing that decides the police and yeah, when you go
48:34 my wife, Yes, investment. this there's an interview room. Uh
48:45 hours and I, so it's fine see Or four day indeed. Have
48:50 dog stuff. two of the Three Science. Well, what's up?
48:58 work table four. Sure. All . Mhm. This one,
49:14 wow, introducing to the other it's time remarked. Uh, you
49:24 , and our region for have been off, but it's all thanks.
49:33 , jesus. It's just a different to do that. Perel director.
49:45 uh just what obviously, uh, , this is a sensible thing that
49:55 straight up the hardest part for have my access better man then a
50:06 improve the performance of the goal potential seem to be and right step the
50:13 school. Uh huh And this is of the example of uh huh.
50:23 . Okay. Oh, they got here, I forgot uh, 64
50:32 on the personal side. But in state, one region of losses off
50:42 mark. But there's no like all these situations before anyone talks before we
50:50 hard. Same for me. Mm , that's kind generous, essentially raised
50:57 south Korea depending upon what they're If there's any dependency between the how
51:06 yourself? God us congress concept. right. Five directors. I bet
51:15 life that they don't want to the things not being the direct result.
51:28 , and these are the things to uh, production claws and set,
51:36 they don't have to do it. , thanks. Makes a much
51:41 Uh, these guys plus governments. a problem. But Oh, guarantee
51:50 the reduction of the subject happens probably of the best their own results.
52:01 trying to use reduction. So that's . Put it on. Found
52:12 It's a paralytic agent testified like the generation. Okay. So that was
52:25 try to compare and the communist forces directors and to some examples show some
52:35 the things he needs to pay particular to. But it's different from being
52:40 terms of use the work during the versus the for construct There's 1 1
52:54 that should be mentioned is Canada lou down from what you want. They
53:02 that's something about effort. The cardinals defining the final section and you make
53:07 violent groups. Yes, I think . In any case it could also
53:11 that the combined that they cannot identify about may not not realizing something that
53:19 actually be. Yeah, that is , disability. Okay. So combining
53:28 that. Right? And I say there are like something being wrong.
53:34 that means if the compiler and result dependence is properly, it's a very
53:41 evenly. That's super cheap. So the other thing or being some prescriptive
53:50 the programmer is convinced the camera para instructor give the compartment. Don't worry
53:59 that. I have worried about So because we are there program is
54:05 then. Yes, there's some clothes . Yeah. So now a little
54:15 more specific about things PG or India is seeking partners the change name.
54:25 to change it on on the So now it's called the NVIDIA Openness
54:33 see compound and I think it happened this past a few months or
54:40 I'll fix it as far as I . So I stole my still the
54:50 conventions or use and typing what you to do. Pg compiler acronym city
55:01 . The commands are still the same of this package video provides rather than
55:07 to visualize friends. So the commands that's the right for something. So
55:15 it turns out it's fine. So you can see Now it's becoming very
55:24 centric club the media for one sec . So leah is essentially building all
55:36 the environment. So it's we use they also know they don't operate on
55:43 own so they need a host and this case the whole space support is
55:53 a general or X- 86-64 that any construction sector to be okay about the
56:04 is called Both into an empty the major processor vendors. No, so
56:12 they support. So they opened the compiler different codes. It has to
56:19 for the host processor, some of will execute on the host the other
56:26 uh they support inside the end, . Process designed as a difference instruction
56:35 . The from instruction sets. some in the basement department of energy
56:44 , big computers and good customer. . So they also that code for
56:51 am uh south come to open some chores arms All right. Yeah.
57:06 or design or servers as well. used to be dominating or mobile platforms
57:15 phones and you're an apple arm processors this which set for life announcer.
57:26 because you know of it. But more then send thunder from the our
57:32 . Oh right processor cops into the oh down. And then they get
57:44 use the public focus on and all things that not saying do not
57:54 It's all about on support for the of being with you. Sure.
58:02 example on the so that's what that now totally. Let's see. So
58:13 next time. So yeah. So are general support enough to get there
58:24 be many minutes that's today. So was december then we'll talk about so
58:33 one thing like you doing corresponding things get in for about the platform that
58:40 for the dispute and it needs to you both about youtube as well as
58:48 whole process both because again, uh back to and question to you.
58:56 program needs to go uh huh little to Okay. They're not documents.
59:07 huh Right. All right. A bit their comparative process. Some extras
59:18 all right. Yeah. For Uh huh. For all kinds of
59:25 , wow. Surrounding very hard And the higher the congress for parts
59:31 be dissipated. So responder was who to what are hundreds. Oh
59:47 Mhm No time. So I'm really is now a very large. So
59:59 , these outcomes hard up. But is really director work. Yeah,
60:10 back there always aggregated of these and on the process system. Yeah.
60:21 plus transcripts. Yeah. Uh that's mom bust it. Well, uh
60:31 name and these are just a very long time or tasks processes when they're
60:43 go on the competition what they So that's not, you know that
60:50 can tell them cards. Mhm electromagnetism means the kind of process from the
61:00 and then what's on the process of is sort of the problem decoration three
61:07 still the current centers. Thanks for time. Uh huh. Have
61:14 you may end up using something that please 40 g which are absolutely I
61:25 it two or 3 generations back so they have I think trying to also
61:34 determined. So there is a The names have used this pascal for
61:40 and the board. Thanks. Oh , so, but I'm trying to
61:52 it out. We have access to have access now too. The 100
62:02 the bridges you no uh that's a to to find it very long.
62:12 in order to get something that doesn't it. So these are uh lost
62:20 Tuesday. Yeah. You want to with good times on the older temporary
62:28 have, they don't have to hear for data science institute. Yes.
62:34 should he. Uh huh. 100 some seriously the member of the
62:49 Okay. I want to stay here . So this is also something from
62:58 ground and that's the capability of tax capability of this issue 31. So
63:10 something I'm going to be used for generation. What it's because it's
63:28 one of the memories were certainly well window or the over the name of
63:38 generation. It has 500 so but it turns it on a little
63:46 faction in this country. Oh It's a factor of eight. It's
63:52 you can run this place and upgrades language is not faithful important 17
64:06 It's nothing. Yeah. Yes. C. C. Oh ah All
64:13 . He said yes. So that's I think. Remember that this sounds
64:19 aircraft so it's sex acronym for I'm really uh single minutes era
64:31 Developed this error detection stand these It's cute And that has eight acceptance
64:42 it takes so that you can do perhaps. Yeah. And that's sort
64:47 the standard industry for trying to analyze corruption. So typically in scientific confusing
64:58 not sure exactly. Mhm. So In that case reduce the 16
65:10 memories. Uh huh. Someone they use eight kids. Yeah citizens.
65:19 haven't been supportive the first eight years provided me. Yes. But then
65:27 circuit for their nine and that is Excite doing 1 1. See some
65:37 number or something. Do you know that's most likely because it's an aircraft
65:51 . Uh huh. Okay. So , so one thing is it's not
65:58 compound so there's a few different ways specify uh for which term you want
66:06 partners in general and code and so I've talked about is to see that
66:12 generated principal to use it because they something for for the past device.
66:20 . And the commander in chief and that is used but that's not the
66:26 thing from the state department and and generate because not everything is cool use
66:32 if it's cold or support the whole so this party that's five actually don't
66:40 to use or on the trying to the postmarks on the process reverses some
66:48 of you. You can specify on in this space does not generate close
66:56 a generous parallel code for the whole is it should tell it to be
67:03 not the same thing happened in that with just a very sequential and the
67:12 on the inside of the A. . C. Other attributes there that
67:18 to test used to be used you can specify the ones.
67:31 And then you under uh ways of targets. Uh huh. A tough
67:43 . The union is contacts and when comes to the post, um these
67:51 you do what you want to do kind of well known as cross
67:57 So I confided so much processor. you want the code generates the
68:06 different process. So now there's an of what you can do, they
68:14 use. So these are is the from a legal platforms and I don't
68:23 to work with the family. You use one of them and generate
68:27 Find out a lot. But that is platform and generate code for certainly
68:38 you're in the process of family that enough commonality in terms of construction said
68:44 can use one or the other, government, the police and they want
68:50 , you don't definitely but your fault spoken normally. Right. Uh
68:59 That's what that's saying. Um, then it wants to have way of
69:08 afternoon or what do you want the to do for the properties of the
69:18 and it's tentative. So, so in this case, you
69:28 the youth, uh, Arnold afterwards violence try to figure out what the
69:37 things and I don't want that to . And they said no other car
69:44 uh, directors and playing off Currently five years in sort of way their
69:54 to be attributes today culture different Yes. Uh, mm.
70:07 All right. And whether it's a light too. Yes, contender confined
70:13 choose, do whatever it wants here his best judgment in getting fast code
70:22 then when it comes to the, views are a million different now to
70:28 in terms of properties of the code constraints on the computer about trajectory.
70:36 . Uh huh. What type of to use a few. I always
70:45 , but fast I'll tell you. it is necessary. Didn't take a
70:50 of depart from that 70 on the so form my dance moves.
70:58 one of the get out of Yeah. Find us. Well uh
71:04 target capability on. Mhm. I'm going to talk about all of them
71:09 just a long list. I put up so you get some sense for
71:15 in the restaurant. Mhm. Lots a lot more than fine. That
71:25 both. Yeah. Find your buddy for first time for the time.
71:33 know, all of them. But some of them will be something you
71:37 to explore. Let's see my And then there's a few quick examples
71:47 this problem but they use this command the party complete freedom uh can be
71:59 to paralyze cold. I think the . Yes. So the one thing
72:04 you will see this also they can have a compartment. Oh yeah.
72:12 it has done to the color so the different uh levels of implications.
72:23 from the next time since it's almost time and we'll show example sorts of
72:34 . Um So I think that's wow. Keep it so on this
72:41 where all specifying the target. That's know what after the IT department the
72:49 . Uh There's one that is harder pursue that there's been a short
72:57 but don't start but there are extensive anyway. That's a start. But
73:05 think that or target protests of but why means keep you so and up
73:24 car is that I'm into something I'll more about that has to be a
73:36 clean the host there. Mhm. you. And whether a lot of
73:50 sponsor to conclude our hand system and even a lot of things through that
74:00 to figure out something more data For . Mhm. They combined the release
74:11 generate mm hmm instructions, move the that fighter a part time time to
74:20 that the best fight to move data one to the other and then they
74:25 consistent has to do. Uh So it's a different stable. And
74:33 you don't have been managed after refused offer from the south explosive. Is
74:39 I know what's going to happen here I'm gonna tell exactly what today.
74:44 also some of your tactics are no far this year. Move this out
74:50 . I will talk about that next . Mhm. And this is the
74:56 of his facts. Okay. I , this is the last time once
75:01 at that. So uh like the of other informational complied applies in terms
75:09 levels of optimization and I find it to do in response to the child
75:16 bank. Yeah. America. So I was like so next time
75:32 talk about the complete examples that I get to today and then we'll do
75:39 demo. Um so this kind of and not see maybe consultation of a
75:49 factor. What triggers before uh to this? Hold it technical solving the
76:01 . Anyone knows about the coldest that . Uh huh. I heard about
76:10 . It's an interesting method as opposed attract business. It's basically relaxation on
76:18 brilliant. Do they have who for on the ground your soul? Uh
76:28 . Number what happened? Because you're your values the money, it's all
76:41 how to do that. See consequences using compiler to do things or using
76:51 a system to do things or start do it yourself and clever. We'll
76:56 about next time and we'll sit down hit this state. So I don't
77:03 that. Look at how it Yeah. Okay. Thank you so
77:11 today then. Uh huh. The media as things and that's the
77:19 color. So what is your Um open it to see as kind
77:30 a higher layer. So you don't to work as a fetus. So
77:35 the openness to see compartment does it to them if you can work with
77:45 programming. So you have put up the difference. Yeah. Yes.
77:53 open as the sea takes your C FORTRAN code compile it's and then called
78:01 for the Gpu is killed a So it's C or four lb input
78:12 and produces Yeah. Who called for GPU and produces assembly code or big
78:21 for the process. So you can for, you have to use lines
78:31 , you can yes, if you to do you prefer to do no
78:34 programming instead of using uh, and thank you can also Lincoln calls with
78:43 seat folds. They should be able do so if there's something that,
78:48 it's more effort to manage a lot details in between are called compared
78:53 Uh huh. So the notion is try to lift the level of programming
78:58 to me cooler is something of a , a simple program we're bringing sexy
79:11 like that perhaps uh, it should the case that it takes less program
79:20 time. So right there. See four triangle that open sec directors and
79:29 and writing articles. Now it's the managed to the volume may actually sometimes
79:38 at least not experienced programmer generate better than somebody that through the cuticle
79:47 So the performance you may get from completely could be better than you produce
79:53 the 2nd level to the level. , it may also be the case
79:59 indicated the comparative famously to do a job and you're called me actually run
80:07 but it should definitely the sort of programmer productivity in terms less time define
80:14 describe what you want to do then for simple as possible. That's the
80:23 as the open and be at the moment of post cold, open,
80:28 and just have open, empty compartment . The details.
