[Beowulf] cluster links checker

[Bill Broadley]

Apparently someone at OSU wrote a similar code that used to be
available at the now dead url:
	http://nowlab.cis.ohio-state.edu/projects/mpi-iba/

The pathscale folks made some changes, and their license says:

Redistribution and use in source and binary forms, with or without

I was pondering writing a few lines of perl to output the result
into a PPM/PGM image to look for patterns (spatial or time based).

In any case here it is (unmodified):
  http://cse.ucdavis.edu/~bill/mpi_nxnlatbw.c

It's only 50 or so lines of c.
