I’ve just installed PGI Fortran 19.4 Community Edition for Windows. However, no MPI-related files seems to have been installed. I’ve copied one of the examples to a working directory, but when I try
pgfortran -o test.exe mpihello.f90 -Mmpi=msmpi
I get the error message:
PGF90-F-0004-Unable to open MODULE file mpi.mod (mpihello.f90: 2)
I’ve manually checked C:\Program Files\PGI\win64\19.4\include and couldn’t find any MSMPI-looking .mod file there (omp and openacc so show up, though).
I’ve tried searching for this error message, but all I could find was this older forum post:
However, there was no choice about MSMPI in the 19.4 installer (in fact, there was no component choice at all, other than a prompt to install Cygwin), and I have not manually installed MSMPI or any Microsoft HPC software before installing PGI Fortran (I did install Visual Studio as per the PGI installation guide).
How do I get PGI Fortran to install with support for MPI? Or how can I add it after the fact and have it work with -Mmpi=msmpi (as opposed to -L, -I, etc.)?
