gm_crawl - self ping over myrinet, going hop by hop on a specified route


MODULE

myrinet


SYNOPSIS

gm_crawl [--size bytes] [--count packets] [--host name] | [-- hop [hop] [hop]...]


DESCRIPTION

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.


OPTIONS

-- 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.


NOTES

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.
