Is there an environment variable option, as well as the openmpi-mca-params.conf to set the equivalent of "--bind-to none"? Similar to how I can specify the environment variable "OMPI_MCA_btl=^openib" instead of the cli param "--mca btl ^openib"?
We're running into a situation where users have a combination of OpenMPI and OpenMP threads, and the threads get constrained to the same processor where the OpenMPI process was launched. As far as we can tell, this started with v1.8.x.
