Hi Alastair,
There are in fact three related MPI transitions, as mpich-4.2.0 is
essentially a mini-transition ;
openmpi 4 -> 5 drops 32-bit support, and has a Fortran API change too
in close inspection: it moves MPI_Integer type from 4 to 8 bytes.
Apologies , I need to correct this; default MPI_Integer does not change
from 4 bytes on openmpi5.
I have yet to upload an mpich transition bug to request transition.
I'm not sure how to do this; the API has changed, but not the ABI? the
SO interface hasn't changed, so how do I write the appropriate BEN code?
Regards
Alastair
