What Ralph said is generally true. If your application completed, this is nothing to worry about. It means that an error occurred on the socket between mpirun ad some other process. However, combind with the travor0 errors in the log files, it could mean that your IPoIB network is acting flaky. That would have me slightly concerned. Enough that I'd consider running some TCP stress tests on the network to make sure it's acting normally.

Hope this helps,

Brian

Hi,

I'd be grateful if someone could explain the meaning of this error
message to me and whether it indicates a hardware problem or
application software issue:

[node2:11881] OOB: Connection to HNP lost
[node1:09876] OOB: Connection to HNP lost

This message is nothing to be concerned about - all it indicates is that mpirun exited before our daemon on your backend nodes did. It's relatively harmless and probably should be eliminated in some future version (except
when developers are running in debug mode).

The message can appear when the timing changes between front and backend
nodes. What happens is:

1. mpirun detects that your processes have all completed. It then orders the
shutdown of the daemons on your backend nodes.

2. each daemon does an orderly shutdown. Just before it terminates, it tells
mpirun that it is done cleaning up and is about to exit

3. when mpirun hears that all daemons are done cleaning up, it exits itself. This is where the timing issue comes into play - if mpirun exits before the
daemon, then you get that error message as the daemon is terminating.

So it's all a question of whether mpirun completes the last few steps to exit before the daemons do. In most cases, the daemons complete first as they have less to do. Sometimes, mpirun manages to get out first, and you
get the message.

I doubt it has anything to do with your hardware issues. Personally, I would just ignore the message - I'll see it gets removed in later releases to
avoid unnecessary confusion.

Hope that helps
Ralph



I have a small cluster which until last week was just fine.
Unfortunately we were hit by a sudden power dip which brought the
cluster down and did significant damage to other servers (blew power
supplies and disk).  Although the cluster machines and the Infiniband
link is up and running jobs I am now getting these errors in user
applications which we've never had before.

The system messages file reports (for node2):
Jul  5 12:08:28 node1 genunix: [ID 408789 kern.notice] NOTICE:

I wonder if this messages are indicative of a hardware problem,
possibly on the Infiniband switch or the host adapters on the cluster
machines.  The cluster software has not been altered but there have
been small changes to the application codes. But I want to rule out
hardware issues because of the power dip first.

Anyone seen this message before and know whether to investigate
hardware first?  I did check the archives but it didn't help. More
info provided below.

Any help appreciate, thanks.

                           with *all* peers during MPI_INIT (vs.
making connections lazily
                           -- upon the first MPI traffic between each

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

MCA pls: parameter "pls_rsh_priority" (current value: "10")
                           Priority of the rsh pls component
MCA pls: parameter "pls_rsh_delay" (current value: "1")
                           Delay (in seconds) between invocations of
the remote agent, but
only used when the "debug" MCA parameter is
true, or the
                           top-level MCA debugging is enabled
(otherwise this value is
                           ignored)
MCA pls: parameter "pls_rsh_reap" (current value: "1")
                           If set to 1, wait for all the processes to
complete before
                           exiting.  Otherwise, quit immediately --
without waiting for
confirmation that all other processes in the job
have
                           completed.
                  MCA pls: parameter "pls_rsh_assume_same_shell"
(current value: "1")
                           If set to 1, assume that the shell on the
remote node is the
                           same as the shell on the local node.
Otherwise, probe for what
                           the remote shell.
                  MCA pls: parameter "pls_rsh_agent" (current value:
"ssh : rsh")
                           The command used to launch executables on
remote nodes
                           (typically either "ssh" or "rsh")
MCA pls: parameter "pls_tm_debug" (current value: "0")
                           Enable debugging of the TM pls
MCA pls: parameter "pls_tm_verbose" (current value: "0")
                           Enable verbose output of the TM pls
MCA pls: parameter "pls_tm_priority" (current value: "75")
                           Default selection priority
MCA pls: parameter "pls_tm_orted" (current value: "orted")
                           Command to use to start proxy orted
MCA pls: parameter "pls_tm_want_path_check" (current
value: "1")
                           Whether the launching process should check
for the pls_tm_orted
                           executable in the PATH before launching
(the TM API does not
                           give an idication of failure; this is a
somewhat-lame
workaround; non-zero values enable this check)
                  MCA sds: parameter "sds" (current value: <none>)
Default selection set of components for the
sds framework
(<none> means "use all components that can be
found")
MCA sds: parameter "sds_base_verbose" (current value: "0")
                           Verbosity level for the sds framework (0 =
no verbosity)
MCA sds: parameter "sds_env_priority" (current value: "0") MCA sds: parameter "sds_pipe_priority" (current value: "0") MCA sds: parameter "sds_seed_priority" (current value: "0") MCA sds: parameter "sds_singleton_priority" (current
value: "0")
