Repeating this claim does not make it true:
  http://www.nas.nasa.gov/Resources/Systems/columbia.html
  - Smallest node have "only" 512 (Itanium) cores
  - Biggest system have 2048 (Itanium) cores
  - These systems are from ~2006 (5 years ago)
  - They are SSI (single system image), not clusters.

If Solaris was so much better in multicore handling, I'll bet you would
be able to point to similar Solaris systems, now can you?
