I unearthed an example for something that's relevant here and probably there, assuming the code hasn't changed significantly in the meantime and the calculation is representative: http://www.hpcadvisorycouncil.com/pdf/CP2K_Analysis_and_Profiling_Intel.pdf but I haven't had the opportunity to test it yet, and the test case I had showed a different communication profile. Did I the promised followup from someone with less positive results ever appear?
