[mpich-discuss] Compiled applications working standalone, but not using mpiexec

[Jayesh Krishna]

Hi,
 I have created a ticket (https://trac.mcs.anl.gov/projects/mpich2/ticket/1580) for the problem.

(PS: I would recommend using Intel fortran compiler OR g77/gfortran from Cygwin for now)
Regards,
Jayesh

No effect, still not producing any output.
