Thank you in advance for putting up with this "newbie" question.

I am running an OPL MIP optimization program and would like to use it to evaluate a few heuristics. Specifically I'd like to compare how fast each heuristic is. One approach is to record the clock time to see how long each solution takes, but, for fair comparison, I would need to run the program on the same computer with the same environemnt (how many other programs are running, memory situation, etc.). Is there another method that's more robust and would allow me to compare different heuristcs on different computers and in different environments? Any suggestion would be highly appreciated.

I can think only of setting

cplex.threads = 1;

to reduce the dimension of processors differences. If the problem is memory intensive you can also limit the memory to that of the slowest computer. Of course, these suggestions give only very partial answer.
