SYNOPSIS
ompi-top [ options ]
Options
ompi-top collects and displays process information in a manner similar to that of the popular "top"
program.
-h | --help
Display help for this command
-pid | --pid <value>
The pid of the mpirun whose processes you want information about, or the name of the file
(specified as file:filename) that contains that info. Note that the ompi-top command must be
executed on the same node as mpirun to use this option.
-uri | --uri <value>
Specify the URI of the mpirun whose processes you want information about, or the name of the
file (specified as file:filename) that contains that info. Note that the ompi-top command does
not have to be executed on the same node as mpirun to use this option.
-rank | --rank <value>
The rank of the processes to be monitored. This can consist of a single rank, or a comma-
separated list of ranks. These can include rank ranges separated by a '-'. If this option is
not provided, or a value of -1 is given, ompi-top will default to displaying information on all
ranks.
-bynode | --bynode
Display the results grouped by node, with each node's processes reported in rank order. If this
option is not provided, ompi-top will default to displaying all results in rank order.
-update-rate | --update-rate <value>
The time (in seconds) between updates of the displayed information. If this option is not
provided, ompi-top will default to executing only once.
-timestamp | --timestamp
Provide an approximate time when each sample was taken. This time is approximate as it only
shows the time when the sample command was issued.
-log-file | --log-file <value>
Log the results to the specified file instead of displaying them to stdout.
DESCRIPTION
ompi-top collects and displays process information in a manner similar to that of the popular "top"
program. It doesn't do the fancy screen display, but does allow you to monitor available process
information (to the limits of the underlying operating system) of processes irrespective of their
location.
