gm_troute - Perform a self ping over a specified route
myrinet
gm_troute [--help] [--debug] [--quiet] [--full] [--timeout msec] [--size bytes] -- hop [hop] [hop]...
This script performs a self ping over a specified route. This is useful for tracking down bad myrinet cables. The route bytes should be in decimal form, but ``0x81'' form should get converted correctly as well.
--debug, --d Print debugging information.
--full, --f Route specified is complete and the path back will not be created.
--quiet, --q Only print output if there are problems.
--timeout, --time, --t <msec> Timeout (in mili-seconds?) to wait for a reply
--size, --s <bytes> Packet size (in bytes) to send
--count, --c <count> Number of packets to send
--help, --h Print manpage.
You only need to specify the route going out. A turnaround hop (0) and the path back will be created UNLESS you specify the --full (full route) flag.
Paths and other defaults are recorded in CConf.pm.
