[neutron-mc] MPI support for SMP in Windows

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
