Linux actually scales very well in this area. My friends in the
supercomputer business tell me that people are successfully using
linux on 1024-way SSI boxes. It doesn't scale quite as well as IRIX,
but a lot of people opt for linux anyways.
For instance, NASA Columbia, which is a cluster of 20 512-way SSI
Altix's is successfully running linux, and comes in #8 on
top500.org's supercomputer list.
yea, i'm pretty familiar with those systems and i would have to say
that the Altix is indeed quite impressive. but, i would not equate
the ability for SGI to implement a large SSI cluster like this to a
"normal" user being able to implement a similar setup with a stock
linus kernel or stock distro for that matter....
