HOWTO fix mpirun problem
 

Hi

i am trying to run OF on multi computers [ip's: 10.9.11.3 and 10.9.11.4]
now when i run command

mpirun --hostfile mechine -np 4 simpleFoam -parallel > log

openfoam@10.9.11.4's password:
--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it could not find an executable:

Executable: simpleFoam
Node: 10.9.11.4

while attempting to start process rank 2.
--------------------------------------------------------------------------

So please someone tell me what to do.

I am using Ubuntu 10.10.

try :mpirun -np 4 --hostfile [hostfilename] simpleFoam -parallel > log

also try: foamJob -p simpleFoam with the machines file in the system folder

make sure all nodes have openFoam or can access OF functions. It could be your slave node 10.9.11.4 hasn't OF installed.
