Open-Coarrays and gfortran-15 with OpenMPI

[amckinstry]

Hi,

I'm maintaining OpenMPI in Debian, and open-coarrays.

As of gfortran >= 14, we get the following error:

OpenMPI uses addresses for windows instead of identical ids on all images for the same token.
    # Therefore we can't use it (yet; and probably never).

Is this ever likely to change, or is there anything we can do about it? As it stands OpenMPI is the default MPI implementation in Debian/Ubuntu and coarrays in Fortran is an important feature for new high-performance libraries like Caffeine.

Thanks Alastair
