More Processors versus Run Times


A recent blog post by Marc-André Carle suggests that "using more processors does not necessarily lead to reduced run times on CPLEX."

Running 90 models with CPLEX 12.4, he concluded (not very strongly though) that "while increasing the number of processor cores results in quicker runs on average, but the effect on individual instances is quite difficult to predict."
