Hi Folks, I'm trying to figure out something about the kind of info pmi's are suppose to be feeding back up in to orte/ompi, partly because native launch doesn't seem to work too well in trunk.
One of the things I'm puzzling about is the purpose of the my_node_rank field in orte_proc_info_t. I'm particularly puzzled, because with the new pmix s2 and cray components, we are returning the NODE RANK (i.e. which NODE in a virtual sense, the proc is on) via a pmix_X_parse_pmap function. See find_my_node in both the pmix_cray_parse_pmap and pmix_s2_parse_pmap functions. This value is subsequently returned when the pmix component is queried with the PMIX_NODE_RANK attribute. But, with s1, we seem to just be assigning the same value to my_node_rank as to my_local_rank, based on the contents of the array returned from PMI_Get_clique_ranks. It appears that in the 1.7/1.8 branch, the behavior is to do the s1 route, irrespective of whether pmi2 from slurm or the pmi.fuzzy from cray is used. Thanks for any help, Howard ------------------------------------------------- Howard Pritchard HPC-5 Los Alamos National Laboratory
