gm_crawl - self ping over myrinet, going hop by hop on a specified route
myrinet
gm_crawl [--size bytes] [--count packets] [--host name] | [-- hop [hop] [hop]...]
Perform a self ping over a specified route, going one hop further each time until we get to the destination
Calls gm_troute to trace along each route.
-- hop [hop] [hop]... Route bytes to traverse. The return path is automaticly generated.
--size <bytes> Packet size to send. Default is set in gm_troute.
--count <packets> Number of packets to send. Default is set in gm_troute.
--host <name> Look up the route to a specific host and crawl it hop by hop
--help Print manpage.
The route bytes (hops) are in decimal form.
The ``--'' is important! Needed to prevent negative route bytes from being interpreted as command line options.
When crawling to a host, the last hop will fail. This is because a host cannot route any packets, only recieve them.
Paths and other defaults are recorded in CConf.pm.
