[Mesa-users] Run MESA on the supercomputer

[Pablo Marchant]

Hi Wenyu,

mesa is not setup to work with multiple nodes at a time, the
parallelization that MESA uses is based on openMP which allows you to use
multiple cores in a single node. I recommend you setup your runs in a
single node with OMP_NUM_THREADS equal to the number of physical cores.

Cheers
