this is a problem of your MPI configuration, or rather your firewall blocking MPI message passing to remote machines. this needs to be properly configured and you need to follow the MPI installation and configuration instructions specific to the MPI package that you installed. have you followed the instructions given here? http://rpm.lammps.org/qe4win.html since you are running on your local machine only, try: mpiexec -localonly 2 pw.x -in si.inp > si.out also, it is *very* unlikely that you'll get any speedup from hyperthreading, more likely the added processes will cause congestion on the memory bus and slow you down. axel. > > > I was running QE using the following command: > > mpiexec -np 4 pw.x <PATH/si.inp> <si.out> > > Please help. > > Regards, > > On Fri, Jan 15, 2016 at 1:23 PM, siddheshwar chopra <[email protected]> > wrote: >> >> Dear Users, >> I want to use the Windows version of Quantum Espresso.
