Hi there So, what else can I look into ? I did more tests, on the same Opteron 6380 machine, using the same binaries, but now using the "DEISA medium benchmark" and the results were interesting. http://qe-forge.org/gf/project/q-e/frs/?action=FrsReleaseView&release_id=45 ifort 13.2 + mkl 11.0 / 8 cores = 1h8m gfortran 4.6 + openblas 0.2.8 / 8 cores = 46m57.62s This is making me even more suspicious of intel compiler being the problem. TIA, Fabricio
