Replying to [comment:4 hinder]:
I wouldn't have expected that. How much is it reduced? Can you give
examples of your speeds in each of the three cases?
I have data from a simulation that ran approximately 9x slower than baseline--however, I have tried to replicate this result without success, as subsequent runs saw no difference between KMP_AFFINITY being exported in the runscript or not. So for now, I suspect there is some other factor involved, or perhaps some sort of temporary issue with stampede. Either way, the issue seems to be unrelated after all.
