DARPA Awards HPC Contracts To IBM, Cray, Not Sun
snedecor writes "DARPA has awarded a third round of funding for the next-generation petascale computing system. IBM and Cray roughly split the $494M, while Sun, with little track record, received none. This is in spite of Sun's radical proposal for proximity communication."
You can pet a dog, you can pet a cat, but you can't petascale.
You can't talk about Wikipedia's flaws on Wikipedia
This is in spite of Sun's radical proposal for proximity communication."
More likely, that was because Sun's radical proposal for proximity communication.
Now, of the two stated applications, which do you think is more interesting to the military? I suppose one could argue defense against bioterror, but it's still kinda scary.
Google's HPC "innovations" are surely software-based, are they not? Not sure they've done anything in the hardware arena that warrants press releases.
The HPCA program is a "cover" (not so cover) funding to companies. The problem is that it is not so clear that it is even good for them. The reason is that "lots" of additional resources from these companies are also diverted for these projects. Since these machines have a "doubtful" application besides the DARPA contract, I think that it may be better for these companies to invest on research more related to their product or may-be products.
For example, Sun Labs was in charge of the DARPA project at Sun. They have "invested" 3 years on that. My question is "what do they have to show?".
They do not have publications on any top computer architecture conference, they do not seem to have anything that may save Sun ass. (At least from
an architecture point of view)
This is not such a strange comment, I have head it from people at IBM research itself. Some people there is not sure that winning is the best thing either.
I used to work at Cray (SGI vintage) as a contractor. It would be nice to think that some jobs are opening up there.

A win for IBM is a win for Linux. Too bad for Sun, but congrats to Linux.
Google are experts at scaling out, not up. Running applications to serve 10000 users at the same time is different from executing one massive program. The main way in which Google and HPC (High Performance Computing, i.e. Supercomputers) overlap is in enormous file systems.
Google's advances are very far from traditional HPC applications like fluid dynamics, weather forcasting, solid body simulations, waveguides, thermal reactions, particle dispersion, oil discovery, etc. Google does data mining, and transactional processing. The very problem that the darpa HPCS program addresses, is that the bulk of the HPC systems sold in the US are just clusters of off-the-sheld database/web-optimized servers. It turns out that these clusters don't deliver very high levels of efficiency, either computationally, or from a power/cooling perspective. Google rolls their own servers, but they still fit into the database/web-optimized server camp. Their software acheivements are all in the data-mining category.
This is not to say that the defense department doesn't need lots of high-end database servers. They use them by the truckload. However, the need for advances in this area are being met by the hardware and software markets. Market forces were not, however, stimulating truly interesting research at the high end of the HPC marketplace. Thus the DoD needed to put together this competition.
This kind of processor is not suited for the high-performance scientific applications, like simulating a nuclear explosion, that DARPA typically runs.
By contrast, IBM is one of the 3 remaining American companies that still makes general-purpose, complex, and powerful cores for crunching scientific applications. The other two companies are AMD and Intel.
Not surprisingly, IBM is always highly competitive in bidding to be the supplier of computing machines to the military. Right now, an IBM system is coordinating the broad-based anti-missile system defending North America.
Sun does have a competitive complex processor: the SPARC64, designed and built by Japanese engineers. However, DARPA was likely seeking only bids using American technology. SPARC64 would not have met the domestic-content qualifications.
Someone else will probably license Sun's proximity communication technology at some point, but it might be the graphics card makers. The proximity communication stuff lets you hook together multiple chips, almost as if they were part of the same die, using a bunch of capacitor-like plates in the chips. This could be very useful for putting some amount of memory (almost) on the cpu die, and putting a very wide bus between that memory and the processor. Both IBM and Cray currently use very expensive ceramic multichip modules to connect multiple dies together, and they are still somewhat limited in the number of connections that can be attached through the modules.
Apart from that, I don't really know what advances they had. Solaris can scale to 100 processors fairly well, but both IBM and Cray have been working on scalable operating systems for systems with tens of thousands of CPUs. The rock processor would likely be a lot faster than sun's current processors, but it's an incremental advance for microprocessors. Both IBM and Cray are working on more radical technology with FPGAs, vector CPUs, highly treaded designs, and sophisticated coprocessors, and very scalable interconnects.
So, IBM and Cray took the prize... Sun lost. And where is the other major US HPC vendor HP? Did they even enter the competition? Do they have anything new to say?
Once you start searching for US chip design and manufacturing firms, you realize that there are tons of them that produce silicon that is general purpose. You only listed the three biggest.
It is your personal duty to fight for what is right on a daily basis. Ignoring injustice is identical to approving
It's Niagara
Niagara II (T2) has one floating point unit per core...so for a T2 outfit with all cores, eight FPUs.
Fortress, the language being developed by a bunch of people led by Guy Steele, was funded as part of the HPCS effort. This means that DARPA is going with IBM or Cray's language (X10 for IBM, Chapel from Cray). According to a press release quoted at http://www.eweek.com/article2/0,1895,2063043,00.as p (but not available at http://www.sun.com/smi/Press/sunflash/index.xml) the work will continue, but how likely is it to succeed?
l Slides9Jun2006.pdf - I thought it was pretty impressive.
Guy Steele gave an excellent talk at OOPSLA on Fortress - the slides are at http://research.sun.com/projects/plrg/PLDITutoria

IBM has been a large governmental contractor from the dark ages... No suprise it isnt continuing. ( and no, that wasnt a slam... there are advantages to working with the same companies you are used to doing business with )
---- Booth was a patriot ----
Anybody saying "Eurabia" should be forced into the body of a Palestinian in Israel about to get killed by an Israeli tank.
Orally? Or perhaps through the palestinian's belly button?
When information is power, privacy is freedom.
DARPA must be simulating giant enemy crabs (or even more appropriately, real-time weapon changing)!
How about, instead, an israeli about to get killed by a palestinian suicide bomber?
Circumcision is child abuse.
I am not asking for the right to compete for those defense contracts, and I was wondering where did I said that. I am telling that this HPC contracts are a smart way to shove billions of dollar of subside for american computer companies. Basically, the US taxpayer is paying for private companies research under the cover of a very broad and vague "Defense Contract" for HPC computing. So, basically, I am claiming for the right to over-tax those products when I import them, because of that subside. It's just international trade, you don't need to get that upset, fat boy.
Your ad could be here!
Personally I was thinking freaky alien technology.
Please, for the good of Humanity, vote Obama.
How about, instead, an israeli about to get killed by a palestinian suicide bomber?
1) That is reserved for people who say "the united states of israel."
2) How funny it is that your sig is about banning circumcision and yet you are a knee-jerker on the israel-vs-the-palestinians issue. Don't stand to close to the mohell.
