source: default
value)
Whether to attempt to disable opening dynamic components or
not
MCA mpi: parameter "mpi_param_check" (current value: "1", data source: default
value)
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)

default
value)
Yield the processor when waiting for MPI communication (for MPI processes, will
default to 1 when o
versubscribing
nodes)

default
value)
How often to progress TCP communications (0 = never, otherwise specified in

environment)
Whether to actually free MPI objects when their handles are
freed

source:
environment)

by MPI_ALLOC_MEM that w
as not freed by
MPI_FREE_MEM
MCA mpi: parameter "mpi_show_mca_params" (current value: <none>, data
source: default
value)
Whether to show all MCA parameter values during MPI_INIT or not (good for
reproducability of MPI jo
bs for debug purposes). Accepted values are all,
default, file, api, and enviro - or a comma delimited combination of
them
MCA mpi: parameter "mpi_show_mca_params_file" (current value: <none>, data
source: default
value)
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)
MCA mpi: parameter "mpi_keep_peer_hostnames" (current value: "1", data source:
default
value)
If nonzero, save the string hostnames of all MPI peer processes (mostly for
error / debugging outpu
t messages). This can add quite a bit of memory
usage to each MPI
process.
MCA mpi: parameter "mpi_abort_delay" (current value: "0", data source: default
value)
If nonzero, print out an identifying message when MPI_ABORT is invoked
(hostname, PID of the proces
s 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.

default
value)
If nonzero, print out a stack trace when MPI_ABORT is
invoked
MCA mpi: parameter "mpi_preconnect_mpi" (current value: "0", data source:
default value, synonyms:

pair)
MCA mpi: parameter "mpi_preconnect_all" (current value: "0", data source:
default value, deprecated, synonym
of:
mpi_preconnect_mpi)
Whether to force MPI processes to fully wire-up the MPI connections between MPI
processes during MP
I_INIT (vs. making connections lazily -- upon the first
MPI traffic between each process peer
pair)
MCA mpi: parameter "mpi_leave_pinned" (current value: "0", data source:
environment)
Whether to use the "leave pinned" protocol or not. Enabling this setting
can help bandwidth perfor
mance when repeatedly sending and receiving large
messages with the same buffers over RDMA-based networks (0 = do not use
"le
ave pinned" protocol, 1 = use "leave pinned" protocol, -1 = allow network
to choose at
runtime).
MCA mpi: parameter "mpi_leave_pinned_pipeline" (current value: "0", data source:
default
value)
Whether to use the "leave pinned pipeline" protocol or
not.
MCA mpi: parameter "mpi_paffinity_alone" (current value: "0", data source:
default
value)
If nonzero, assume that this job is the only (set of) process(es) running on
each node and bind pro
cesses to processors, starting with processor ID
0
MCA mpi: parameter "mpi_warn_on_fork" (current value: "1", data source: default
value)
If nonzero, issue a warning if program forks under conditions that could cause
system
errors
MCA mpi: information "mpi_have_sparse_group_storage" (value: "0", data source:
default
value)
Whether this Open MPI installation supports storing of data in MPI groups in
"sparse" formats (good
for extremely large process count MPI jobs that
create many
communicators/groups)
MCA mpi: parameter "mpi_use_sparse_group_storage" (current value: "0", data
source: default
value)
Whether to use "sparse" storage formats for MPI groups (only relevant if
mpi_have_sparse_group_storage is
1)
MCA orte: parameter "orte_base_help_aggregate" (current value: "1", data source:
default
value)
If orte_base_help_aggregate is true, duplicate help messages will be aggregated
rather than display
ed individually. This can be helpful for parallel
jobs that experience multiple identical failures; rather than print out th
e
same help/failure message N times, display it once with a count of how many
processes sent the same
message.
MCA orte: parameter "orte_tmpdir_base" (current value: <none>, data
source: default
value)
Base of the session directory
tree
MCA orte: parameter "orte_no_session_dirs" (current value: <none>, data
source: default
value)
Prohibited locations for session directories (multiple locations separated by
',',
default=NULL)
MCA orte: parameter "orte_debug" (current value: "0", data source: default
value)
Top-level ORTE debug switch (default verbosity:
1)
MCA orte: parameter "orte_debug_verbose" (current value: "-1", data source:
default
value)
Verbosity level for ORTE debug messages (default:
1)
MCA orte: parameter "orte_debug_daemons" (current value: "0", data source:
default
value)
Whether to debug the ORTE daemons or
not
MCA orte: parameter "orte_debug_daemons_file" (current value: "0", data source:
default
value)
Whether want stdout/stderr of daemons to go to a file or
not
MCA orte: parameter "orte_leave_session_attached" (current value: "0", data
source: default
value)
Whether applications and/or daemons should leave their sessions attached so that
any output can be
received - this allows X forwarding without all the
attendant debugging
output
MCA orte: parameter "orte_do_not_launch" (current value: "0", data source:
default
value)
Perform all necessary operations to prepare to launch the application, but do
not actually launch
it
MCA orte: parameter "orte_daemon_spin" (current value: "0", data source: default
value)
Have any orteds spin until we can connect a debugger to
them
MCA orte: parameter "orte_daemon_fail" (current value: "-1", data source:
default
value)
Have the specified orted fail after init for debugging
purposes
MCA orte: parameter "orte_daemon_fail_delay" (current value: "0", data source:
default
value)
Have the specified orted fail after specified number of seconds (default: 0
=> no
delay)
MCA orte: parameter "orte_heartbeat_rate" (current value: "0", data source:
default
value)
Seconds between checks for daemon state-of-health (default: 0 => do not
check)
MCA orte: parameter "orte_startup_timeout" (current value: "0", data source:

Request that critical timing loops be
measured

np@ -start @executable@
@executable_argv@ @single_app@ : fxp @mpirun@ -a @mpirun_args@", data source:
default
value)
Sequence of user-level debuggers to search for in
orterun

default
value)

value)
Time to wait [in usecs/proc] before aborting an ORTE operation (default: 1000
usec/proc)

source: default
value)

path)
