Hi dear FOAMers,

I want to use two computers in a local network in order to make my calculations in OpenFOAM 2.2 much faster.
I wish to run the calculations from cfd4 on the machines cfd3 and cfd4, which both have 4 processors (cpu), that means I want to use 8 cpus for the calculation. By the way I got the names of the computers by typing hostname in the terminal. The operating system on both computers is Kubuntu 12.04.
In order to run applications in parallel I followed the instructions given by http://www.openfoam.org/docs/user/ru...s-parallel.php .
So I first of all wrote the file "decomposeParDict" in order to break up the geometry and the field of my calculation in 8 subdomains. Afterwards I have written the file machines.
After creating the mesh and decomposing my mesh and field on cfd4 I typed

mpirun -hostfile machines -np 8 sprayFoam -parallel > log &

in order to get the process using the sprayFoam solver started.
Unfortunately I get the following error:

mpirun was unable to launch the specified application as it could not find an executable:
Executable: sprayFoam
while attempting to start process rank 4.

I know that process rank 0 to 3 belong to cfd4 and process rank 4 to 7 belong to cfd3, that means that he cannot find the executable on cfd3.
Can anybody help me through this problem?

I would be very pleased for any hint. Thank you very much in advance.

best regards

Ray
