mpiifort and preprocessing flags

Kevin_McGrattan — Fri, 01 Dec 2023 14:55:38 GMT

I have a short Fortran/MPI test code on my Windows 10 computer that simply writes out a text string that includes a preprocessing variable string called GITHASH_PP:

program test_mpiifort
use mpi_f08
implicit none

integer size, rank, namelen, ierr
character (len=MPI_MAX_PROCESSOR_NAME) :: name
type(mpi_status) :: stat

call MPI_INIT (ierr)
call MPI_COMM_SIZE (MPI_COMM_WORLD, size, ierr)
call MPI_COMM_RANK (MPI_COMM_WORLD, rank, ierr)
call MPI_GET_PROCESSOR_NAME (name, namelen, ierr)

write(0,'(A,I0,A)') 'Rank ',rank,' writes the string:'//TRIM(GITHASH_PP)

call MPI_FINALIZE (ierr)

end

I compile at the Intel 64 command prompt

C:\Users\mcgratta\Documents\firemodels_forked\fds\Utilities\test_mpi>mpiifort -fc=ifx -o test_mpiifort -fpp -DGITHASH_PP="'Nov7'" test_mpiifort.f90
mpifc.bat for the Intel(R) MPI Library 2021.11 for Windows*

-out:test_mpiifort.exe
-subsystem:console
"/LIBPATH:C:\Program Files (x86)\Intel\oneAPI\mpi\latest\env\\..\lib"
"/LIBPATH:C:\Program Files (x86)\Intel\oneAPI\mpi\latest\env\\..\lib"
impi.lib
test_mpiifort.obj

I then run the job:

C:\Users\mcgratta\Documents\firemodels_forked\fds\Utilities\test_mpi>mpiexec -n 4 test_mpiifort
Rank 0 writes the string: Nov7
Rank 3 writes the string: Nov7
Rank 2 writes the string: Nov7
Rank 1 writes the string: Nov7

Everything works. However, if I add a space to the text string 'Nov 7', the compilation fails:

C:\Users\mcgratta\Documents\firemodels_forked\fds\Utilities\test_mpi>mpiifort -fc=ifx -o test_mpiifort -fpp -DGITHASH_PP="'Nov 7'" test_mpiifort.f90

compilation aborted for test_mpiifort.f90 (code 1)
ERROR in the compiling/linking [1]

I have tried every possible combination of single quotes, double quotes, escape characters like backslashes, but nothing works. These do work with ifort, and I know that mpiifort is just a script. But how do we pass PP directives with mpiifort?

Moving this over to the HPC Toolkit Forum. The folks there know about MPI.

@Kevin_McGrattan

thanks for reporting this, it seems to be a shortcoming of the mpiifort script.

@Kevin_McGrattan

please try to use this

mpiifort -fc=ifx -o test_mpiifort "-fpp -DGITHASH_PP='Nov 7'" test_mpiifort.f90

Best
