[OMPI users] Settings oversubscribe as default?

[Florian Lindner]

Hello,

I can use --oversubscribe to enable oversubscribing. What is OpenMPI way to set this as a default, e.g. through a config file option or an environment variable?

Thanks,
Florian

The equivalent MCA param is rmaps_base_oversubscribe=1. You can add OMPI_MCA_rmaps_base_oversubscribe to your environ, or set rmaps_base_oversubscribe in your default MCA param file.
