Hello!

I need make a fair comparisons between different formulations using MIP solvers (mainly Gurobi).  For example, I need to plot the average gap versus time, or plot the fraction of replications where the optimal solution was found versus time. Because the abscissa of the graphs is time I need to use the same hardware/software platform for all comparisons. 

Is the NEOS Server a valid (hardware) platform to realize this comparisons? 

I looked in internet, but I don't find information if the memory RAM and the processor capacity is the same in each submidted job.

Thanks for any help or advice!

The NEOS machines all have the same processors, Xeon X5660s, with
hyperthreading disabled on neos-3 and neos-4 (not that it really
matters, since jobs are generally not allowed to use more than 1
core). neos-1 and neos-2 also have more RAM, 64GB instead of 24GB,
though jobs themselves are restricted to 3GB.
