[mpich-discuss] debugging mpi without mpiexec -gdb

[William Pearson]

I have an MPICH2 program that works fine with mpiexec -gdb -np 5 ...., but crashes quite quickly without the -gdb.

Is there some combination of -machinefile and other parameters that I can give directly to my program, so that I can run it under gdb without using mpiexec?
