A–mpirun Options Summary

Stats Options

A-4 IB6054601-00 H

-k, -kill-timeout seconds

This option indicates the time to wait for other ranks after the first rank exits.

Default: 60

-listen-addr <hostname>|<IPv4>

This option specifies which hostname (or IPv4 address) to listen on for incoming

socket connections. It is useful for an mpirun front-end multihomed host. By

default, mpirun assumes that ranks can independently resolve the hostname

obtained on the head node with gethostname(2). To change the default, put

this option in the global mpirun.defaults file or a user-local file.

-runscript

This is the script with which to run the node program.

-t, -timeout seconds

This option waits for specified time (in seconds) for each node to establish

connection back to mpirun. If seconds is -1 (negative one), mpirun will wait

indefinitely.

Default: 60

Stats Options

-M [=stats_types], -print-stats [=stats_types]

Statistics include minimum, maximum, and median values for message

transmission protocols as well as more detailed information for expected and

unexpected message reception. If the option is provided without an argument,

stats_types is assumed to be mpi.

The following stats_types can be specified:

One or more statistics types can be specified by separating them with a comma.

For example, -print-stats=ipath,counters displays InfiniPath

communication protocol as well as low-level device counter statistics. For details,

see “MPI Stats” on page D-31.
