[Beowulf] cluster links checker

[Kozin, I (Igor)]

Hello,
we would like to have a simple tool which tests that all the 
nodes are properly connected in the cluster. Something akin 
to Microway's MPI link checker but free and not necessarily
MPI based. Fancy graphics is optional too.
A report pointing to a suspicious node based on
average latency and bandwidth between all the nodes
would probably be sufficient to begin with.
Although this is straightforward to code I'm wondering
if there is already something available.

Any comments on Microway's MPI link checker are also welcome!

Many thanks in advance
