Hi dear foamers,

I installed OpenFOAM 2.2.0 on a cluster. There is no problem running serial...on the head node. But when I ran it in parallel, the following errors popped out:

--> FOAM FATAL ERROR:
Trying to use the dummy Pstream library.
This dummy library cannot be used in parallel mode

From function UPstream::init(int& argc, char**& argv)
in file UPstream.C at line 37.

FOAM exiting


I don't have the same problem when I installed and run OpenFOAM on a local machine.

I checked some related threads on this forum....but can't really get it working by using the advice found...

I checked the bashrc file in /etc and the mpi environment is set correctly:
export WM_MPLIB=OPENMPI

I don't understand why OpenFOAM still tried to use the dummy Pstream.... this is really doing my head in....

Can anyone help me out on this? Thank you very much.

Regards
Callum
