I think you either use Open MPI or MPICH. Can you try setting the environment variable
when invoking MPI by adding the -x or -env (-envlist, ...) option like in:

Open MPI
    mpirun -x GFORTRAN_UNFORMATTED_BUFFER_SIZE=1024000 ...

cf. https://www.open-mpi.org/doc/v1.8/man1/mpirun.1.php

or

MPICH:
    mpiexec -env GFORTRAN_UNFORMATTED_BUFFER_SIZE 1024000 ...

cf. https://www.mpich.org/static/docs/v3.1/www1/mpiexec.html

See linked man pages for details and additional environment-related options.

Tobias
