Hello,
The problem that I have been having is running my application across
multiple nodes. Here are the details of what I have debugged thus far.
I am going to follow the numbered list from the getting help page: (
http://www.open-mpi.org/community/help/)
1 ) I checked for a solution to this problem throughout the FAQ as well as
the mailing list, but was unsuccessful in resolving the issue.
2) Version of openmpi: openmpi v1.4.4
3) I found the config.log, but it is very large, so I was unable to attach
it. If you would like me to I can upload it and provide a link.
4) ompi_info --all output: see attached file 'ompi_info_all.txt'
5)'ompi_info -v ompi full --parsable' (ran using: 'mpirun --bynode *--hostfile
my_hostfile* --tag-output ompi_info -v ompi full --parsable'

6) Detailed description:
I have a fortran90 application that solves a system of linear equations
using LU Decomposition. The application has three components. matrix_fill ,
matrix_decomp, and matrix_solve. The application has a make option for
compiling the application using MPI.
I have successfully compiled the application using openmpi v1.4.4, and can
run the application.
I utilize the '--hostfile' parameter when executing mpirun. For testing
purposes I modified this file to see if I could narrow down the problem.
I am able to run the program locally (on the same node that mpirun is being
executed on) when utilizing 1 or greater than 1 slots (i was able to run
with 12 slots on a single node). I am also able to mpirun on 1 or 2 slots
on a single remote node as well.
The problem occurs when I try to have two nodes work together, such that I
specify two separate nodes in the hostfile and use -np 2 when executing
mpirun).
Here is an example of the my_hostfile (when the problem occurs)
intel15
intel16
and this is an example of the command used:
[intel15] > mpirun --hostfile my_hostfile -np 2 matrix_fill
The problem occurs at a second call to MPI_BARRIER. The first MPI_BARRIER
call is successful, but on the second one it hangs.
Here is a basic outline of the code for up to the point of where the
program hangs:
[code]
CALL MPI_INIT(ierr)
CALL MPI_COMM_RANK(MPI_COMM_WORLD, my_rank, ierr)
CALL MPI_COMM_SIZE(MPI_COMM_WORLD, group_size, ierr)
! creates buffers for each image
!synchronize buffers
CALL MPI_BARRIER(MPI_COMM_WORLD, ierr)
WRITE(6, *) 'Initializing I/O for image #', my_image
CALL flushio
! At this barrier the program hangs and must be killed using CTRL+C
CALL MPI_BARRIER(MPI_COMM_WORLD, ierr)
[/code]
The hang only occurs when trying to use -np 2 (or larger) and on multiple
nodes that are networked together. At first I thought it was a firewall
issue, so i ran 'service iptables stop' as root, but sadly this did not fix
the problem. I am able to ssh between these nodes without a password, and
the nodes are apart of a cluster of approximately 20 nodes at University of
Maryland *B*altimore County.
7) Network info: see attached network_info.txt file:
I have been trying to determine the root of this error for the past week,
but with no success.
Any help would be greatly appreciated.
Thank you,
Tim

value: "0", data source: default value)
Whether to attempt to disable opening dynamic
components or not
MCA mpi: parameter "mpi_paffinity_alone" (current value: "0",
data source: default value, synonym of: opal_paffinity_alone)
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_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)

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.

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

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).

Whether to use the "leave pinned pipeline" protocol or
not.
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)
