Tony KynastonHOST
17:15
yeah, right.
Cameron ReillyHOST

One of the founders of CDC was Seymour Cray, developed some of the fastest mainframes in the world.
Cameron ReillyHOST
17:23
During the 1970s, he left and founded Cray Research and pretty much is the father of supercomputers.
Cameron ReillyHOST
17:32
So, you know, pretty much all of the AI stuff that's going on today, you can trace back to Seymour Cray one way or another.
Cameron ReillyHOST
17:39
I remember my...
Tony KynastonHOST
17:40
Jensen Huang of his day.
Cameron ReillyHOST
18:43
I'll come down and we'll build a tunnel under your new home when you move in.
Cameron ReillyHOST
18:48
See if the elves come to us.
John GustafsonGUEST
17:47
So one of the rules of the HPL benchmark based on LINPACK is that it has to use 64-bit representation of floating point.
John GustafsonGUEST
17:55
It does not have to be a standard floating point because that benchmark has been around since the days of things like the Cray-1.
John GustafsonGUEST
18:02
I've actually written a paper about this that's being refereed right now.
John GustafsonGUEST
18:07
But the original benchmark was to solve a 100 by 100 set of equations with 64-bit floats and see how fast you could do that using just standard Gaussian elimination with pivoting.
John GustafsonGUEST
22:31
And then the, because they really struggled to build a 48 times 48 integer multiplier for the significance.
John GustafsonGUEST
22:38
And in fact, they did a sloppy job of it and left off the least significant bits.
John GustafsonGUEST
22:42
As a result, on a Cray-1, you could take A times B and get a different answer from B times A.
John GustafsonGUEST
22:47
Interesting.
ToddAUDIENCE
91:59
Maybe the servers, because as far as I understood it, there were some special chips that had to be really cool.
ToddAUDIENCE
92:06
Like, you know, I remember the Cray supercomputer and all that.
ToddAUDIENCE
92:09
Apparently, these quantum computers need to be cool, but things keep getting miniaturized.
ToddAUDIENCE
92:18
And she isn't supposed to be making me think about it.
Bill DallyGUEST
9:07
... that they have is they have, they have a, they have a pretty neat interconnection network with the, uh, with the training TPUs of the 3D torus.
Bill DallyGUEST
9:13
I built a lot of supercomputers, you know, both at MIT and with Cray in, in the '90s, with 3D torus networks-
Dave PattersonMODERATOR
9:19
Yeah
Bill DallyGUEST
9:19
... and so I'm, I'm very fond of that, and I can see the hand of the co-author of my book, Brian James-
Glenn LockwoodGUEST
16:32
Cori, like Gordon, was a super cool, very innovative system.
Glenn LockwoodGUEST
16:38
Cori was a Cray XC30, I want to say.
Glenn LockwoodGUEST
16:42
But it was the first large-scale deployment of Intel's Knights Landing processor.
Glenn LockwoodGUEST
16:47
I'm sure you remember that and how exotic it was.
NicoleHOST
19:00
blast from the past there.
Glenn LockwoodGUEST
19:03
Yeah, we've talked about this plenty in its heyday in the mid-2010s.
Glenn LockwoodGUEST
19:11
But Cori was, it shipped with this burst buffer technology called DataWarp that was co-developed between NERSC, Los Alamos National Lab, and Cray.
Glenn LockwoodGUEST
19:22
And DataWarp was designed to solve this problem that Flash was too expensive to put everywhere.
Michael KennedyHOST
30:44
What a different time it is for universities, and I think w- they're going through a, a similar upheaval, I guess, is the word.
Michael KennedyHOST
30:51
When I was in university, and we're talking, like, '90s, there was a giant Cray supercomputer or maybe a, a, a couple of supercomputers at the heart of the university in some basement, and you could get access to that if you needed mega computing resources.
Michael KennedyHOST
31:06
And now it's just, you know, scaled into some ginormous cloud infrastructure, and the limit is really just how much are they gonna give you, not what, what does the university have in its basement or something like that, which is really interesting.
Shaun ChuahGUEST
31:19
Well, uh, I mean, there are still some universities that are trying to build their own clusters.
Artificial IntelligenceNARRATOR
0:40
The machine that knows everything.
Artificial IntelligenceNARRATOR

T.T.M.O. unveils the Crayon Telecluster.
Artificial IntelligenceNARRATOR

A room-sized oracle that files away every encyclopedia ever printed and answers back in plain English.
Artificial IntelligenceNARRATOR
0:51
The hardware, TT, M, O's Cray Intelli cluster is a complete state-of-the-art solution that allows you to discover everything known to man.
David LeitchHOST
11:04
And when I was reading about the weather forecasting system, it seems that it's making quite a difference in weather forecasting.
David LeitchHOST
11:11
The-- I believe the Bureau used to run its system, or used to run s- has a supercomputer, a Cray supercomputer, which as it turns out is quite energy intensive [chuckles].
David LeitchHOST
11:22
And that, uh, the Europeans and Google and everyone have, have tried to apply AI machine learning to weather forecasting.
David LeitchHOST
11:31
And since May, uh, our weather forecasts also make use of such a system.
