SGI & NASA Plan 10240-Processor Altix Cluster 202

Posted by timothy from the like-a-cluster-of-grapes dept.
green pizza writes "NASA has announced plans to cluster twenty 512-processor Silicon Graphics Inc Altix supercomputers connected to a 500-terabyte SGI InfiniteStorage SAN. The Altix uses Itanium2 CPUs running Linux atop an Origin 3000-derrived architecture. NASA and SGI scaled Linux to 512 CPUs late last year. There are also strong hints that SGI plans to bring its clustered ATI graphics to Altix in the near future. Lots of neat big iron project on the horizon!"

        For the conspiracy theorists who believe the moon landings were faked a collaboration between NASA and SGI on simulated exploration will just provide a basis to think that the Mars missions will not only be faked, they wont even use real actors next and the whole mission will be CGI.

        So when we do 'land' on Mars, if the astonauts burst into a song and dance extravaganza during the planting the flag ceremony then the job was probably outsourced to India. If the ceremony involves a 10 hour trek up a mountain and is interrupted by hordes of attacking Martians that must be defeated by the 6 astronauts then they probably got Peter Jackson to do it. If the whole mission is really lame and not quite what you were hoping for, look no futher than George Lucas.

      By boosting its computing capacity ten-fold through Project Columbia, the NASA Advanced Supercomputing Facility (NAS) will be able to more effectively handle such critical projects as simulating future space missions, projecting the impact of human activity on weather patterns, and designing safe and efficient space exploration vehicles and aircraft. The present collaboration builds upon the highly successful 8-year partnership that last year developed the world's first 512-processor Linux server - based on standard, "off-the-shelf" microprocessor and open source technology - the SGI Altix at NASA Ames Research Center named 'Kalpana' after Columbia astronaut and Ames alumna Kalpana Chawla.

      I don't know what NASA would do with this, but I know what our group would do with it.

      We always need machines. You could give me 1024 machines and I'd still need more.

      For example, I study fluids currently. I may simulate 4,000,000 particles and it may take 3 weeks for my simulation to finish. If I had 10240 nodes, it may only take a day. Or perhaps I could simulate MORE particles for longer. There are all sorts of advantages to having this many machines hooked up.

      One thing I can tell you for sure is that there most likely will not be *1* job that uses all of these at once. There are probably several researchers that are using it simultaneously and have a slice of the machines. Press releases like this are often time misleading because usually the CPUs are split between several jobs and researchers and research groups and what not.

      Not to steal NASA's thunder -- a cluster this big is impressive.

          Not yet, but Cray is working on it in something called Red Storm.

          Itanium's "better" floating point performance than Opteron is confined to some pretty specialised benchmarks. Over all, Opteron is a more efficient design, runs cooler than itanium, has better compilers, better software support, is cheaper and had more room to scale to much higher clock speeds.

        Well, until the final numbers come out, we aren't speculating on performance. Needless to say we hope to claim the top slot in computing power. Also, keep in mind that parts availability is a major concern. We are assembling the system to be fully up and running by SuperComputing '05 in November. Intel has fully committed to delivering all 10K CPU's with no problems. Also, perhaps the biggest reason for Intel, is SGI was chosen as the vendor and they use Intel.

        Agent Green:

        Cheaper? Not likely, you'd have to buy the high-speed interconnect to make it worthwhile. And the Opterons perform fairly poorly in larger clusters, since they have the NUMA latency penalties locally on each node. Checking the Top500 list, a cluster of 256 Opteron 246 using Infiniband will perform worse than a cluster of 256 Xeon 2.8GHz using Infiniband. The scariest example is that a cluster of 256 P4's@3GHz using Gigabit Ethernet outperforms the Opteron cluster.....

        Important to note is that the Linpack test doesn't stress the interconnect that much. The more a task stresses the interconnect, the more the Opteron cluster will be penalized. There's one exception though, and that's the Cray Octiga Bay systems.... And if you go that route, it costs _at_ _least_ as much as an Altix system
      • SGI and Cray have been working on I2 systems for at least a year or two before Opteron was released. People dismiss Itanium2 but it does perform pretty well, much better than the original Itanium.

        I think Itanium has some features not available in Opteron. One I know for sure is available lock-stepping for extra fault tolerance, according to an AMD engineer I asked, AMD has no plans for it.

      Windows, on the other hand, has (with a few exceptions, now gone) been tied to the x86 architecture - meaning there's never even been a need to support more than a relatively small number of processers, and not even the possibility (until recently) of 64-bitness. (Yes, there was NT for the Alpha. It's gone.)
