[mpich-discuss] Debugging mpi program using mpich

[Mathieu Dutour]

Dear all,

I used mpich-3.0.1 with debugging options and the program ran correctly
but at the end returned some errors indicated later.
I thank mpich for finding those errors that other mpi implementation did
not find but I wonder if there is a way to transform this into more useful
debugging informations.
