C – Troubleshooting InfiniPath MPI Troubleshooting

Q

If this file is not present or the node has not been rebooted after the infinipath RPM has been installed, a failure message similar to this will be generated:

$ mpirun -m ~/tmp/sm -np 2 -mpi_latency 1000 1000000

node-00:1.ipath_update_tid_err: failed: Cannot allocate memory mpi_latency: /fs2/scratch/infinipath-build-2.0/mpi-2.0/mpich/psm/src

mq_ips.c:691:

mq_ipath_sendcts: Assertion ‘rc == 0’ failed. MPIRUN: Node program unexpectedly quit. Exiting.

You can check the ulimit warning will be given if

-lon all the nodes by running ipath_checkout. A is less that 4096.

There are two possible solutions to this. If InfiniPath is not installed on the node where you start the job, set this value in the following way (as root).

#ulimit -l 65536

Or, if you have installed InfiniPath on the node, reboot it to insure that /etc/initscript is run.

Error Messages Generated by mpirun

In the sections below, types of mpirun error messages are described. They fall into these categories:

Messages from the InfiniPath Library

MPI messages

Messages relating to the InfiniPath driver and InfiniBand links

Messages generated by mpirun follow a general format:

program_name: message

function_name: message

Messages may also have different prefixes, such and ipath_ or psm_, which will indicate in which part of the software the errors are occurring.

C.8.12.1

Messages from the InfiniPath Library

These messages may appear in the mpirun output.

The first set are error messages, which indicate internal problems and should be reported to Support.

Trying to cancel invalid timer (EOC)

sender rank rank is out of range (notification) sender rank rank is out of range (ack)

Reached TIMER_TYPE_EOC while processing timers
