I work on cluster (x86_64) with more than 3000 processors.
OS - Linux 2.6.18.
The compiler - Intel 10.1.
MPI - HP-MPI.
OpenFOAM 1.4.1.

I started icoFoam with the task "cavity". At sequent. run has received result of calculations. At parallel run the problem does not give out errors, but does not give out also result. (Decomposition of area of calculations on 8 processors, since on one node - 8 processors). If at parallel run not to specify in a command of start an option "-parallel" the task leaves on a node, it is carried out on one processor, calculates results and message, that MPI_Init () it was not caused.

In what there can be a problem?
