Default Re: I need a serious workhorse computer for complex simulations

You're absolutely right, in that i don't know what i need. The more i think about it, the more i realize that i'm lost and need more guidance before purchasing the right computer.

I'll try to answer your questions.

The simulation is mimicking 200,000 typical statistical "experiments" (well, each permutation is). To be specific, i believe that the statistic P-replication (P-rep) underestimates the true probability of replication. Thus, i've created 200,000 "experiments" using various population parameters (permutations of effect sizes) to determine what the actual probability of replication is, and then compare the mean/median of those to what P-rep predicts. The experiments are basically t-tests with an n = 10, 20, 40, and 100. They are all running simultaneously in the program. The program is written in C++. I didn't write (my programmer did), but i do have access to the source code if necessary.

Sorry, i don't know what "parallelization (eg. MPI, OpenMP)" means.

Thanks for your help in this. I do appreciate it.
