MPICH Parallel Run Error on the Windows Server2003
 
Hi,

I run the MPICH Parallel on the Windows Server 2003 Dual CPU machine cluster. I can use the MPICH Local Parallel for Windows mode and got the converge results. When I used the MPICH Distributed Parallel for Windows mode to run parallel cases, it showed the Solver Terminated error as following.

--------------

An error has occurred in cfx5solve:

The ANSYS CFX solver has terminated without writing a results file. Command on host cluster exited with return code 0.

--------------

I have checked the RSH service and the RSH can return value.

How should I resolve this error in ANSYS CFX solver for MPICH parallel?

Thanks a lot.

Are you sure your MPICH Deamon is running with correct user registered?

Hi, Bian

How do I check the correct user registered for my MPICH Deamon?

I registerd the user that same account in RSH service.

Thanks a lot.

If you followed the setting up instruction, you would see MPICH service in running services (right click on "my computer", click "manage", select "services")

One more thing, turn the Windows firewall off. Otherwise, the distributed parallel might not run.
