distributed mpich problem

Trevor

I am having problems with distributed MPICH between two XP32 and XP64 boxes. This is what I have done. I have the same user with admin rights logged onto both systems as a local user. The rsh and mpich services are configured to use the above mentioned user. I am running CFX10 SP1 on both boxes. On the XP64 box I have installed CFX to c:\1\cfx so that I did not have to worry about spaces in the path, but the XP32 box has it installed in c:\program files\ansys inc\… etc. The correct short path names have been entered into the hosts.ccl files on both machines correctly, the hosts files are identical.

The system works fine when running distributed PVM, although I do get 2 warnings 1. Warning! rsh connection to host X produces the following output before the output of the command: Terminal readThe handle is invalid. This may cause problems spawning parallel slaves, especially on Windows.

2. Warning! rsh connection to host X produces the following output after the output of the command: : It could indicate that an rshd service from a different vendor is running, which may not provide the necessary functionality. This may cause problems spawning parallel slaves.

These are warnings that I happen at the start of the mpich run as well. I would like to fix them up as they may be having an effect on the mpich run.

But when I run distributed MPICH I get the following error

-------------- 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. --------------

That is it, no more explanation that that. The services (rsh and mpich) are running on both machines, the distributed PVM works ok, but with the above described warnings that I would like to clear up. I don't know what the problem is.

Can anyone help with this?

Thanks Trevor P
