You didn't say how much RAM your sims use. I have problems with our sims
hitting 32-bit memory limits. (doing ASIC verification simulations). The
Sun U-80s use all 4GB RAM and start swapping,the Linux x86 machines seg
fault the sim at 3GB memory usage.

So, another possibility for your consideration.
