Running in parallel
 
Hello Foamers,
i am trying to run the simulation in parallel with two processor, after decomposition,
when i run mpirun, i am getting the following error,

--------------------------------------------------------------------------
Failed to find the following executable:

Host: localhost.localdomain
Executable: computerlist

Cannot continue.
--------------------------------------------------------------------------


can any one help me to overcome this problem?

Hi,

it is probably a missing machine file necessary for the mpirun. Have a look how it has to to be defined.

Regards, Markus

hi
 
Hello foamers,
i have run simulation with 2 processor, i think it is ok.
now the problem is, after finishing the calculation, I am trying to execute reconstructPar command, when i am executing reconstructPar i am getting the following error,
can any one help me overcome this problem.
