[bug#39588] gnu: Add mpich, scalapack-mpich, mumps-mpich, pt-scotch-mpich, python-mpi4py-mpich

[Maurice Brémond]

Hi,

I made an strace on scalapack tests (blacs tests)

XL.gz
Description: strace -f

I cannot see where it goes wrong, but it should be in the trace.

I also compiled another package I use with mpich, adjoinable-mpi, and it
is ok (as there is no checks inside it...). I can use it to run an ocean
model and everything works. So it is the same thing as your example I
think, the end user can use mpich, but the guix daemon cannot.
