I'm having a lot of trouble getting mpirun to work in parallel with OpenFOAM 2.1.0. I compiled it from Thirdparty-2.1.0 with Allwmake and it compiled without errors. I then managed to run decomposePar on my case nicely but when i try to invoke mpirun according to user guide it gives me the following error:

$mpirun -np 2 buoyantBoussinesqSimpleFoam -parallel


--> 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

--------------------------------------------------------------------------
mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.

It also gives the same error message with Test-parallel. mpirun seems to be working otherwise, just not with the -parallel option. For example i can run following without any problems:

$mpirun -np 2 Test-parallel

I'm totally stuck with this problem, which seems to be somehow related to Pstream library. I haven't made modifications to files in Thirdparty-2.1.0 or in OpenFOAM installation. There seems to be others with the same errors, but no solutions that i could find.

Any help is very much appreciated, as my case could really use more than one core.
