[Pw_forum] Computational Speed for pw.x

[Amar Singh]

Dear Lorenzo Paulatto,​Thanks for the response. I have few questions based upon some literature I found online.​1. I found somewhere that open-mpi may provide parallelization upto few processors, but not for a large number of them. If so, could MPI be a better option.  ​2. I do not have Intel MKL on my system, could this be the reason for slow processing speed with open-mpi.thanks​Amar
