Hi guys,
I'm trying to run an example program, mpi-ring, on a rocks cluster.
When launched via sge with 8 processors (we have 8 procs per node),
the program works fine, but with any more processors and the program
fails.
I'm using open-mpi 1.3.2, included below, at end of post, is output of
ompi_info -all
Any help with this vexing problem is appreciated.
thanks,
Eli

--------------------------------------------------------------------------
A daemon (pid 31176) died unexpectedly with status 1 while attempting
to launch so we are aborting.
There may be more information reported by the environment (see above).
This may be because the daemon was unable to find all the needed shared
libraries on the remote node. You may set your LD_LIBRARY_PATH to have
the
location of the shared libraries on the remote nodes and this will
automatically be forwarded to the remote nodes.

default value)
Whether to show errors for components that
failed to load or not
MCA mca: parameter
"mca_component_disable_dlopen" (current value: "0", data 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)
MCA mpi: parameter "mpi_yield_when_idle" (current
value: "-1", data source: default value)
Yield the processor when waiting for MPI
communication (for MPI processes, will default to 1
when oversubscribing nodes)
MCA mpi: parameter "mpi_event_tick_rate" (current
value: "-1", data source: default value)
How often to progress TCP communications (0
= never, otherwise specified in microseconds)
MCA mpi: parameter "mpi_show_handle_leaks" (current
value: "0", data source: default value)
Whether MPI_FINALIZE shows all MPI handles
that were not freed or not
MCA mpi: parameter "mpi_no_free_handles" (current
value: "0", data source: default value)
Whether to actually free MPI objects when
their handles are freed
MCA mpi: parameter
"mpi_show_mpi_alloc_mem_leaks" (current value: "0", data source:
default value)
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
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 jobs 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 output 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
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.
MCA mpi: parameter "mpi_abort_print_stack" (current
value: "0", data source: 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:
mpi_preconnect_all)
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)
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 MPI_INIT (vs. making connections
lazily -- upon the first MPI traffic between each
process peer pair)
MCA mpi: parameter "mpi_leave_pinned" (current
value: "-1", data source: default value)
Whether to use the "leave pinned" protocol
or not. Enabling this setting can help bandwidth
performance when repeatedly sending and
receiving large messages with the same buffers over
RDMA-based networks (0 = do not use "leave
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 processes 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
displayed individually. This can be
helpful for parallel jobs that experience multiple
identical failures; rather than print out
the 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: default value)
Milliseconds/daemon to wait for startup
before declaring failed_to_start (default: 0 => do
not check)
MCA orte: parameter "orte_timing" (current value:
"0", data source: default value)
Request that critical timing loops be
measured
MCA orte: parameter
"orte_base_user_debugger" (current value: "totalview @mpirun@ -a
@mpirun_args@ :
ddt -n @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
MCA orte: parameter "orte_abort_timeout" (current
value: "1", data source: default value)
Max time to wait [in secs] before aborting
an ORTE operation (default: 1sec)
MCA orte: parameter "orte_timeout_step" (current
value: "1000", data source: default value)
Time to wait [in usecs/proc] before
aborting an ORTE operation (default: 1000 usec/proc)
MCA orte: parameter "orte_default_hostfile" (current
value: <none>, data source: default value)
Name of the default hostfile (relative or
absolute path)
MCA orte: parameter
"orte_keep_fqdn_hostnames" (current value: "0", data source: default
value)
