Processor Affinity - additional processors

[Guest]

I see that there are up to 32 CPU options available to set the Processor
Affinity, but only the first two are not grayed-out. What hardware would
need to be installed in order to have more CPUs listed?

I have a dual-CPU machine that I use for analysis of scientific data (mostly
number-crunching, not much disk access). Even with two CPUs, it is
considerably slower than what I would like. I really don't want to re-write
the software to explicitly distribute processes among a large set of
processors. I would like to incorporate more CPUs and have the threads be
automatically balanced between all the available processors (like what I have
now with a dual-CPU machine).

Also, which OS would be better for distributing threads? Windows 2000, XP,
or Server?

Thanks for your help,

Chris

For more than two processors, you'll want server.
