aujamal20 is an unknown quantity at this point
Hi,
I am running openfoam simulation in parallel on a machine using 4 out of 12 processors and thats working nice. Now I just get an other server without any openfoam installation on it.
Now I want to run the same simulation on two machines (servers) one with openfoam installation and the other one without openfoam installation using 4 processors from each machine.... can i do this or not and if i can, then please let me know....

thanks.

Greetings Jamal,

Technically a parallel application can only run if the respective software is somehow provided to all of the machines that will be using it. In addition, you better make sure that both machines are running the same architecture, or at least in the lower common architecture, namely both should run in 64 bit or 32 bit.

So, there are two possible solutions:
  1. You install OpenFOAM on the other machine as well, in the same way and/or path. This way you don't loose much performance on the start-up, since all binaries are already present in both machines.
  2. Or you share the installation folder on the first machine to the other machine, such as using NFS.
Best regards,
Bruno
