  222.                           If nonzero, assume that this job is the only (set of) process(es) running on each node and bind processes to processors, starting with processor ID 0

  224.                           Whether you want MPI API parameters checked at run-time or not.  Possible values are 0 (no checking) and 1 (perform checking at run-time)
  225.                  MCA mpi: parameter "mpi_yield_when_idle" (current value: "-1", data source: default value)
  226.                           Yield the processor when waiting for MPI communication (for MPI processes, will default to 1 when oversubscribing nodes)

  234.                           If >0, MPI_FINALIZE will show up to this many instances of memory allocated by MPI_ALLOC_MEM that was not freed by MPI_FREE_MEM
  235.                  MCA mpi: parameter "mpi_show_mca_params" (current value: <none>, data source: default value)
  236.                           Whether to show all MCA parameter values during MPI_INIT or not (good for reproducability of MPI jobs for debug purposes). Accepted values are all, default, file, api, and enviro - or a comma delimited combination of them
  237.                  MCA mpi: parameter "mpi_show_mca_params_file" (current value: <none>, data source: default value)
  238.                           If mpi_show_mca_params is true, setting this string to a valid filename tells Open MPI to dump all the MCA parameter values into a file suitable for reading via the mca_param_files parameter (good for reproducability of MPI jobs)
  239.                  MCA mpi: parameter "mpi_keep_peer_hostnames" (current value: "1", data source: default value)
  240.                           If nonzero, save the string hostnames of all MPI peer processes (mostly for error / debugging output messages).  This can add quite a bit of memory usage to each MPI process.

  242.                           If nonzero, print out an identifying message when MPI_ABORT is invoked (hostname, PID of the process that called MPI_ABORT) and delay for that many seconds before exiting (a negative delay value means to never abort).  This allows attaching of a debugger before quitting the job.
  243.                  MCA mpi: parameter "mpi_abort_print_stack" (current value: "0", data source: default value)
  244.                           If nonzero, print out a stack trace when MPI_ABORT is invoked
  245.                  MCA mpi: parameter "mpi_preconnect_mpi" (current value: "0", data source: default value, synonyms: mpi_preconnect_all)
  246.                           Whether to force MPI processes to fully wire-up the MPI connections between MPI processes during MPI_INIT (vs. making connections lazily -- upon the first MPI traffic between each process peer pair)
  247.                  MCA mpi: parameter "mpi_preconnect_all" (current value: "0", data source: default value, deprecated, synonym of: mpi_preconnect_mpi)
  248.                           Whether to force MPI processes to fully wire-up the MPI connections between MPI processes during MPI_INIT (vs. making connections lazily -- upon the first MPI traffic between each process peer pair)
  249.                  MCA mpi: parameter "mpi_leave_pinned" (current value: "-1", data source: default value)
