There are a bunch of projects that let you do this. The cheapest
approach at home is probably to use something like OpenMOSIX, or the project. I used to use the former but never got
the performance I wanted (for obvious reasons).

I believe SGI have their own internal "simulation" stuff (more
"partitioning") but running on real SGI NUMA boxen (this is the
impression I get from lunchtime discussions with SGI types). Simulation
is going to be dog slow in comparison to anything real.

Best stick with one of the suggestions already made. NUMA is designed
for real physical hardware, what you want is a cheap cluster.
