[mpich-discuss] I need help

[Jayesh Krishna]

Hi,
 If your application (executable) works with MSMPI it should have been compiled using MSMPI. You should recompile your application (or ask for a build from the application developers) with MPICH2 for it to work with MPICH2.

Regards,
Jayesh

Hi, 
Please note my findings: 


# Did you re-compile the application with MPICH2 (the correct include/lib paths etc)? 

Answer: No becase I have no source code. 

# Can you run the application without mpiexec (freefem++-mpi.exe)? 

Answer: Yes it works. 

# Can you run the application using mpiexec with one process (mpiexec -n 1 freefem++-mpi.exe)? 

Answer: No, Still it hanges the application. 

# Did you try providing the complete path to mpiexec to launch the application (C:\Progra~1\MPICH2\bin\mpiexec -n 1 freefem++-mpi.exe)? 

Answer: Same problem 


Waiting for your kind response 

Tahir Mushtaq.

> freefem++ is a free software for fluid dynamics which is built under C++. It has freefem++-mpi.exe (64 bit) as a utality to run its code for parallel processing by using MPI. I tried its examples and gets error as mentioned earlier. Howerver, it works well with MS-MPI (Microsoft MPI) while it hange with MPICH2 (64 bit).
