mpiexec missing in pacman msmpi

[chandreshiit]

Hi,

I installed MSMPI via pacman (pacman -S mingw-w64-x86_64-msmpi) but mpiexec command is missing and MSYS Mingw64 says that command not found though mpicc/mpic++ are there.

1. mpiexec belongs to the MS-MPI runtime which needs to be installed separately from the msmpi package which is a mere SDK.

2. By default, MSYS2 shell launched by the msys2_shell.cmd does not include system Windows paths hence mpiexec won't be accessible from within. One needs the -full-path command line parameter for that.
