I'm a user on Stampede 2. After successfully running the tutorial 25-km CONUS simulation, I was trying to run a test simulation using a model domain that is not pre-configured (following https://ufs-srweather-app.readthedocs.io/en/ufs-v1.0.0/LAMGrids.html). All the pre-processing steps (make_grid, make_orog, make_sfc, make_ics, make_lbcs) finished successfully, but the forecast was not able to integrate forward. The error messages are:
FATAL from PE 2: set_group_update: mpp_domains_stack overflow, call mpp_domains_set_stack_size( 2033281) from all PEs.
My gut feeling is that this might be associated with the number of processors, but I was not able to find any information regarding how to set the number of processors or the domain decomposition.
