mpirun during simulation under Docker (start with ./startOpenFOAM)

spalartallmaras · February 10, 2020, 09:29

Hello,

I think I have to solve this problem cuz I can not start parallel running if I start my OpenFOAM with Docker (./startOpenFOAM).

If I want to start mpirun, then I can see always this message, even I am logged in as non-root-user,

Code:

mpirun has detected an attempt to run as root.
Running at root is *strongly* discouraged as any mistake (e.g., in
defining TMPDIR) or bug can result in catastrophic damage to the OS
file system, leaving your system in an unusable state.

You can override this protection by adding the --allow-run-as-root
option to your cmd line. However, we reiterate our strong advice
against doing so - please do so at your own risk.

1. Is there any way to run mpirun under docker?
2. Or is there any way to install openfoam-v1912 without docker in RHEL7?

It is really easy to install openfoam without docker in Ubuntu, aber I have to use RHEL7 cuz it is not my personal computer...
