Intel MPI : Fortran 2008 Error

[aruhela]

Hi Intel Support Team,

One of our staff is trying to compile a Fortran 2008 program with GNU Fortran compilers.  He has observed, "f951: Fatal Error: Reading module 'mpi_f08' at line 1 column 2: Unexpected EOF" for the line "use mpi_f08" in his program.

Program count.F90
  use mpi_f08
end Program GetCount

[staff f08:467] module load intel
Lmod is automatically replacing "gcc/9.1.0" with "intel/19.1.1".
Due to MODULEPATH changes, the following have been reloaded:
  1) impi/19.0.9     2) petsc/3.16     3) python3/3.9.2


[staff f08:468] mpif90   -c count.F90
[staff f08:469] module load gcc
Lmod is automatically replacing "intel/19.1.1" with "gcc/9.1.0".
Due to MODULEPATH changes, the following have been reloaded:

[staff f08:470] mpif90   -c count.F90
f951: Fatal Error: Reading module 'mpi_f08' at line 1 column 2: Unexpected EOF
compilation terminated.

As the documentation on the Intel webpage https://www.intel.com/content/www/us/en/developer/articles/release-notes/mpi-library-release-notes-linux.html show Fortran 2008 bindings are supported in intel MPI,  could you please suggest us a solution to the issue?

Thanks,

Hi,

Thank you for posting in Intel Communities.

We are able to reproduce your issue on Ubuntu 18.04. we will get back to you soon regarding this issue.

However, we tried compiling the below-attached sample code(hello.f90) using mpiifort which worked fine.

Thanks & Regards,

Hemanth

Hi,

>>"We are able to reproduce your issue on Ubuntu 18.04. we will get back to you soon regarding this issue."

Intel MPI doesn't support f08 bindings with gfortran (mpif90 wrapper)in Linux. You can only build it with ifort (mpiifort).

Thanks & Regards,

Thanks Hemanth,

Do you plan to add support in further releases?

Thanks Hemanth,

We wish to see the f08 binding in the next software release. You may close the ticket.
