I have two seperate issues but I believe they may be linked:

1. fpi.exe is hanging when run

This is the example fortran available with the MPICH2 download. I compile the program through code::blocks with the GNU Fortran compiler with link library ~MPICH2\lib\fmpich2g and compiler search directory \MPICH2\include

The program appears to compile fine with no errors/flags etc. When I run the program from the code::bloacks IDE it runs fine. But when in the command prompt (logged in as asministrator) the command

mpiexec -n 4 fpi

hangs. Note the same command for the c file (mpiexec -n 4 cpi) runs fine.

2. My Fortran program gives an error when run through mpiexec. Again, the program is compiled with the same settings as above. However, when using the command

mpiexec -n 4 <myexefile>

I receive the following error message

System Details:

Windows 7

64 bit system but code::blocks and MPICH are 32 bit

MPICH version is mpich2 1.4.1p1

Thanks in advance,
