Hello,
I'm working on an MPI application for which I recently started using Open MPI
instead of LAM/MPI. Both with Open MPI and LAM/MPI it mostly runs ok, but
there're a number of cases under which the application terminates abnormally
when using LAM/MPI, and hangs when using Open MPI. I haven't been able to
reduce the example reproducing the problem, so every time it takes about an
hour of running time before the application hangs. It hangs right before it's
supposed to end properly. The master and all the slave processes are showing in
"top" consuming 100% CPU. The application just hangs there like that until I
interrupt it.
Here's the command line:
orterun --prefix /path/to/openmpi -mca btl tcp,self -x PATH -x LD_LIBRARY_PATH
--hostfile hostfile1 /path/to/app_executable <app params>
hostfile1:
host1 slots=3
host2 slots=4
host3 slots=4
host4 slots=4
host5 slots=4
host6 slots=4
host7 slots=4
host8 slots=4
host9 slots=4
host10 slots=4
host11 slots=4
host12 slots=4
host13 slots=4
host14 slots=4
Each host is a dual-CPU dual-core Intel box running Red Hat Enterprise Server 4.
I caught the following error messages on app's stderr during the run:
[host1][0,1,0][btl_tcp_frag.c:202:mca_btl_tcp_frag_recv] mca_btl_tcp_frag_recv:
readv failed with errno=110
[host8][0,1,29][btl_tcp_frag.c:202:mca_btl_tcp_frag_recv]
mca_btl_tcp_frag_recv: readv failed with errno=113
<later>
[host1][0,1,0][btl_tcp_frag.c:202:mca_btl_tcp_frag_recv] mca_btl_tcp_frag_recv:
readv failed with errno=110
Excerpts from strace output, and ompi_info are attached below.
Any advice would be greatly appreciated!
Thanks in advance,
Daniel

Path for MCA configuration files containing default
parameter values
MCA mca: parameter "mca_component_path" (current value:
"/path/to/openmpi/lib/openmpi:/home/user1/.openmpi/components")
Path where to look for Open MPI and ORTE components
MCA mca: parameter "mca_verbose" (current value: <none>)
Top-level verbosity parameter
MCA mca: parameter "mca_component_show_load_errors" (current
value: "1")
Whether to show errors for components that failed to
load or not
MCA mca: parameter "mca_component_disable_dlopen" (current
value: "0")
Whether to attempt to disable opening dynamic
components or not
MCA mpi: parameter "mpi_param_check" (current value: "1")
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: "0")
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")
How often to progress TCP communications (0 = never,
otherwise specified in microseconds)
MCA mpi: parameter "mpi_show_handle_leaks" (current value: "0")
Whether MPI_FINALIZE shows all MPI handles that were
not freed or not
MCA mpi: parameter "mpi_no_free_handles" (current value: "0")
Whether to actually free MPI objects when their
handles are freed
MCA mpi: parameter "mpi_show_mca_params" (current value: "0")
Whether to show all MCA parameter value during
MPI_INIT or not (good for reproducability of MPI jobs)
MCA mpi: parameter "mpi_show_mca_params_file" (current value:
<none>)
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_paffinity_alone" (current value: "0")
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_keep_peer_hostnames" (current value:
"1")
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")
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")
If nonzero, print out a stack trace when MPI_ABORT is
invoked
MCA mpi: parameter "mpi_preconnect_all" (current value: "0")
Whether to force MPI processes to create connections
/ warmup with *all* peers during MPI_INIT (vs. making connections lazily --

MCA mpi: parameter "mpi_preconnect_oob" (current value: "0")
Whether to force MPI processes to fully wire-up the
OOB system between MPI processes.
MCA mpi: parameter "mpi_leave_pinned" (current value: "0")
Whether to use the "leave pinned" protocol or not.
Enabling this setting can help bandwidth performance when repeatedly sending

MCA mpi: parameter "mpi_leave_pinned_pipeline" (current value:
"0")
Whether to use the "leave pinned pipeline" protocol
or not.
MCA orte: parameter "orte_debug" (current value: "0")
Top-level ORTE debug switch
MCA orte: parameter "orte_no_daemonize" (current value: "0")
Whether to properly daemonize the ORTE daemons or not
MCA orte: parameter "orte_base_user_debugger" (current value:
"totalview @mpirun@ -a @mpirun_args@ : fxp @mpirun@ -a @mpirun_args@")
Sequence of user-level debuggers to search for in
orterun
MCA orte: parameter "orte_abort_timeout" (current value: "10")
Time to wait [in seconds] before giving up on
aborting an ORTE operation
MCA orte: parameter "orte_timing" (current value: "0")
Request that critical timing loops be measured

If a signal is received, display the stack trace frame
MCA backtrace: parameter "backtrace" (current value: <none>)
Default selection set of components for the backtrace
framework (<none> means "use all components that can be found")
MCA backtrace: parameter "backtrace_base_verbose" (current value:
