Hi there,

Apologies if this is off topic, but I'm trying to check
what speeds the login nodes to our cluster and BlueGene
can talk at and the only 10Gb/s iperf server I've been
given access to so far (run by AARNET) showed me just
under 1Gb/s.

I've already demonstrated I can talk between 2 boxes
on the same Force10 switch at 9.3Gb/s with iperf but
the ITS network people don't have any test systems
to help me pin down where the bottleneck is.

So if anyone on the list had a system that they could
run an iperf server on at a mutually convenient time
I'd be most grateful!

The code is on SourceForge and is easy to compile (and
is packaged already in Debian and Ubuntu).

cheers,
Chris
