According to the guide, the MPI settings for running without the workflow manager on Linux platforms require to put RUN_CMD_UTILS/FCST/POST option in config.sh.
However, I am wondering how to set up the nodes number on my case. I know that I can set the number of nodes and MPI processors with NODES_RUN_FCST and PPN_RUN_FCST. But are these options for Workflow tasks only? Can I set these on my case (i.e. Linux platform without workflow manager)?
