[petsc-users] misleading "mpich" messages

[Kong, Fande]

Thanks, Satish,

One more question: will petsc complain different versions of other
implementations such as intel MPI and IBM MPI? For example, configure with
a version of intel MPI, and compile with another version of intel MPI. Do
we have error messages on this?

Fande,
