SGI & NASA Plan 10240-Processor Altix Cluster 202
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!"

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.

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.

A stock whose price continues to climb can allow the company to essentially print money by issuing new stock (if the price climbs fast enough existing shareholders don't generally notice or care that you're diluting the pool), but beyond that, how does share price influence the company's actual operations?
Going further OT, I think Apple should have bought SGI. They could have gained credibility in the scientific visualation and industrial sectors and had a tidy little OS and GUI that could have spanned from the receptionist desk to the research machine room, in addition to gaining some high-end server solutions far beyond their XServes.
Somehow it seems that something like this could have develped into a really cool desktop solution that would allow users to run applications locally and remotely on big iron (yes, X-windows style) but with the ease of use and friendliness Apple's known for.
10240-Processor Altix Cluster vs IBM Blue Gene? (Score:3, Informative)
In SGIs press release they state that they hope to get the top spot on the 500 list. As all know IBM is expecting Blue Gene http://www.research.ibm.com/bluegene/ to take the top spot in 2005.
It looks like SGIs architecture for the Altix is better than the Blue Gene, but 10,240 intel CPUs is just going to be outpowered by the 65,536 PowerPC CPUs in Blue Gene.
Now the ultimate machine would have SGIs architecute (memory) and #CPUs per node using the PowerPC CPU. We know that IBM and SGI would never colaborate on something like this, but can't a geek dream!

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.

The MIPS/IRIX systems have VPro graphics, yes. But those are not from NVIDIA. VPro for MIPS/IRIX is the last chipset to be developed inhouse.
The confusion comes from the fact that Sgi marketing thought it would be a good idea to give both the PC and Irix graphics cards the same brand: VPro.
They currently don't have anything newer for their workstations, but their newest Onyx (visualization system) computers use a couple of Ati cards for their graphics. It's called the UltimateVision [sgi.com].

No, SGI bought part of Cray a few years back and Sun bought another part (that's where the Sun E10k came from). SGI sold it's part of Cray to a company called Tera which then changed its name to Cray.

Yes, The Vpro series only resembles Nvidia chipes because after it was completed, most of the team went to work for Nvidia and created the geforce with lots of the same ideas behind it. So the original GeForce chips were more like cut down Vpro's than the VPro's were soupped up GeForces if that makes any sense.

BlueGene/L:
From http://www.research.ibm.com/bluegene/BG_External_
Each node will contain 8 CPUs. There are 128 Nodes per rack and 64 racks. This yields the 65536 total CPUs.
10,240 Processor SGI Altix: 512 CPUs per node X 20 nodes = 10,240 total CPUs.
Now that the groundwork has been layed. You can see that the Blue Gene/L only uses 8 CPUs/node while Altix uses 512/node. As you know there is a huge advantage of having more CPUs that share a common bus and have direct access to the memory. Also SGI is well known for having some of the top numbers for memory throughput.
Therefore one can see that the ultimate HPC Monster would have SGIs architecture as far as bus, memory and #CPUs per node using IBMs PowerPC. Of course this would require a joint effore and wouldn't happen. The only way I could see something like this happen is if IBM bought SGI.
I didn't go much into details about why the number of CPUs sharing a common bus is such an advantage. But one shouldn't have to. Anybody with any architecture knowledge should get the argument.

You can only print stock if your stock value is fast rising, and that's not that many companies. Otherwise it has the same effect as printing money -- devaluing the existing shareholder's shares.
Regardless, heavy trade in a corporation's stock actually does very little to raise capital for the company.

What few people seem to know (and appreciate) is that SGI has been one of the major contributors to Linux over the last few years. Not only XFS, but lots of commands, utilities and system functions have been enhanced, based on IRIX code. This has been a significant boost to Linux, and it's only fair that SGI reaps some benefits.
I wish SGI and its employees the best of luck!
