Hello all,
I'm having trouble using MPI support on my Window's based PC. I have MPICH
installed and am able to successfully get the example programs provided to
use both processors in my PC, however, I am unsuccessful at getting McStas
to do the same.
The problem is I cannot compile the file to generate an executable with MPI
support. Mpicc is a unix based program, and I cannot use it. Also when
using mcrun with the --mpi=2 argument, I get the following message in the
command prompt:
mcrun: No MPI/grid machine list.
Grid disabled, MPI will run locally...
Define /.mcstas-hosts
or C:\McStas\lib/tools/perl/mcstas-host
or use option --machines=<file>!
mcrun: You have no mpicc/mpirun available, --mpi disabled...
Any suggestions?
Thanks,
Aaron
