The server nspace created by the slurm pmix plugin is potentially useful to understand, since presumably openmpi works well with it. This list was created by running git grep PMIXP_KVP_CREATE in src/plugins/mpi/pmix.

  • PMIX_TMPDIR
  • PMIX_NSDIR
  • PMIX_TDIR_RMCLEAN
  • PMIX_JOBID pmix.jobid
  • PMIX_NODEID
  • PMIX_APPNUM
  • PMIX_APPLDR pmix.aldr
  • PMIX_GLOBAL_RANK pmix.grank
  • PMIX_APP_RANK pmix.apprank
  • PMIX_LOCAL_RANK
  • PMIX_NODE_RANK
  • PMIX_HOSTNAME
  • PMIX_UNIV_SIZE
  • PMIX_JOB_SIZE
  • PMIX_LOCAL_SIZE
  • PMIX_NODE_SIZE pmix.node.size
  • PMIX_MAX_PROCS pmix.max.size
  • PMIX_NODE_MAP
  • PMIX_PROC_MAP
  • PMIX_LOCAL_PEERS
  • PMIX_LOCALLDR pmix.lldr (appears to be set for one node job but not for > 1)

The following probably do not need to be set by this plugin

  • PMIX_ANL_MAP (probably only needed for pmi-1, pmi-2 shims)
  • PMIX_LOCAL_TOPO (removed in spec v4.0)
  • PMIX_SPAWNED (absent == false, and we don't support PMIx_Spawn())
