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

[Hugh Cassidy]

Hello,
I have MPICH2 32 installed on Windows 7. The cpi.exe example works fine 
when I run, for example, the command:
mpiexec -n 4 cpi.exe

I have been able to compile, using gfortran, the fpi.f example. 
Furthermore, I can run the generate application in a standalone fashion:
fpi.exe

However, when I attempt to use mpiexec, it doesn't work:
mpiexec -n 4 fpi.exe
Doesn't seem to do anything - I'm just returned immediately to the 
command prompt with no output displayed. Does anyone know why this may 
be happening? I'm experiencing the same problem trying to run another 
application that makes use of mpi - it runs standalone, but not using 
the mpiexec command. I'm guessing this means there is some problem with 
the compilation step?

Thanks!
