mmmn036 is on a distinguished road

I am struggling to run jobs in parallel on Red Hat 4.4.7-3 cluster.

I used system ICC (Intel) compiler, system mvapich2-2.0b for $WM_MPI.

Edited the etc/bashrc as-

export WM_COMPILER=Icc

Edited the etc/config/ as-


export FOAM_MPI=mvapich2-system
export MPI_ARCH_PATH="/opt/apps/intel14/mvapich2/2.0b/"
_foamAddPath $MPI_ARCH_PATH/bin
_foamAddLib $MPI_ARCH_PATH/lib

Then compile OpenFOAM.

It works fine with single processor.

But when I run the breakdam case in parallel- it shows me the following 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

Any help or suggestion will be highly appreciated.
