[mpich-discuss] [MPICH users] Problems using MPICH instead of OpenMPI

[Kenneth Raffenetti]

One thing to be careful of is that you are not mixing an mpiexec from 
openmpi with an application linked with mpich. This can cause issues 
with processes being able to connect to each other, which is likely what 
is happening in your runs.

Please double check that you are using the mpiexec from mpich.
