Or if your not locked into your OS, download their Caos NSA Linux that comes with Perceus, Warewulf, ofed, openmpi, etc and you have a cluster up in a few minutes. We were running HPL runs in 15 minutes on 512 nodes. The power of open source. :) If you want HPC, go to Infiscale.com and get Perceus.

I will be very interested in the performance of this (and the other solutions) that are coming to market right now around software-enabled shared memory. Please tell us the “other solutions” Thanks.

HPC Centers turn on cpusets anyhow and limit the full use of the SMP capabilities. ScaleMP and other software only solutions like RNA Networks may be good for use as a ramdisk since that would likely still be faster than disk I/O. Hardware/software combo's like 3Leaf will be better in cache coherency but will not address the underlying latency advantage that SGI has.
