Goodmorning everyone,
I'm trying to run a simulation in parallel using openFoam 8 with Windows subsystem for linux (WSL). When I launch mpirun, it gives me the following warning: WARNING: Linux kernel CMA support was requested via the btl_vader_single_copy_mechanism MCA variable, but CMA support is not available due to restrictive ptrace settings. The vader shared memory BTL will fall back on another single-copy mechanism if one is available. This may result in lower performance. Then the simulation proceeds, but the results that it gives are as if the simulation was runned only on a single core and not in parallel. Can anyone help me? Thank you in advance! |
