Hi, I am looking for an efficient example of using the Parallel Toolkit. Many other people on this forum seem to have noted what I have also found to be the case, that the ParallelMap and ParallelTable commands aren't terribly efficient. The example code in ParEval.nb, for instance ParallelMap[FactorInteger, (10^Range[20, 40] )/9] only seems to run about 20% faster on a six-node cluster vs my laptop. Does anyone have an example of how to solve this same problem using an efficient parallel technique? I am fairly new to Mathematica, so please be explicit. Thanks, -geoff Geoff Hulette MIT Academic Computing ghulette at mit.edu
