But AFIK, you can run Modelsim multiple times and each would run on a different core. This way, you'll be able to run multiple simulations at the same time.
Questa has traditionally been the top level simulator that is the most expensive - but Im sure Ive seen things recently that they are trying to rebrand all modelsim under the questa name - so maybe?
I think that the key aspect to consider in HDL simulation is the parallelism of the application or more exactly lack thereof - parallelism.
A machine that runs at speed X (assuming speed X is possible and peripheral resources such as memory are abundant) will ALWAYS have higher performance then N machines running together at speed X / N.
The less parallelism the problem exhibits - the bigger will be the performance edge to the faster machine.

I do not know can i ask here but today i get a problem with Modelsim. I use "student version" Modelsim 10.3d for Altera Quartus II, and today (after a half of year!) i get error 211.
