[mpich-discuss] How many ports for MPIEXEC_PORT_RANGE?

[Huiwei Lu]

Hi Josef,

I am not familiar with MPICH_PORT_RANGE but I think you can experiment how
many ports does each process need. For starters, you can probably estimate
a minimum of 6 ports per process.

There was an old post about MPICH_PORT_RANGE but I think the suggestion is
still valid today.
