MPI error on Ubuntu 9.04

Hey OpenFOAM professionals,

a colleague of me runs OpenFOAM on a Ubuntu 9.04 VirtualMachine. If he likes to run his case parallel on local CPUs he get the following error message:

[0]
[0]
[0] Wrong number of arguments, expected 0 found 2
[0]
[0]
FOAM parallel run exiting
[0]
[VMUbuntu:04166] MPI_ABORT invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 1
mpirun noticed that job rank 1 with PID 4167 on node VMUbuntu exited on signal 15 (Terminated).

Does anybody know what's wrong?

Kind regards,
Fabian

Problem solved!
It has been a user error

Cheers, Fabian

Which virtual machine have you been using?

I tried VirtualBox from Sun, but this software is not able to address multiple CPUs from the host system so far.

Hey sega,

you are right. He can't run in parallel.
Well no error occurs during decompose or when the solver is called. But he simply "distributes" the parts to the same CPU.

Cheers, Fabian
