[Pw_forum] INSTALL QE ON MAC PRO SIX CORE (INTEL XEON E5)

[reyna mendez camacho]

Thank yo very much. The problem was solved with: enable-parallel and disable-openmp, export MPIF90 = mpif90.
currently already he is running.
I have a doubt:How do I know if you are using all the cores?.
Thanks again.Best regards
M. C.  Reyna Méndez Camacho.
