[mvapich-discuss] Readme mpiexec example is not working

[bright.yang at vaisala.com]

The syntax might be the same, it worked at 217 but it gave an error in Mvapich216
# mpiexec -machinefile 2_12hosts -n 24 ./wrf.exe
/share/apps/mvapich216/bin/mpdroot: open failed for root's mpd conf filempiexec_kratos.vaisala.com (__init__ 1208): forked process failed; status=255

Where should I put .mpd.conf file for root account?

Thanks.

Bright Yang

It uses the same syntax.  Please refer to the corresponding userguides
available at http://mvapich.cse.ohio-state.edu/support/ for more
information regarding how to use mvapich2.
