It might be too obvious, and it depends on your actual use case, but you 
could also just have the iperf daemon, or `iperf -s`, running on each of 
these cluster system with a restrictive iptable firewall in place so that 
only other hosts in your cluster can use it.

With that you can do whatever iperf measurements you want to do to and from 
any other host of your cluster.  But this won't archive nor plot anything.

Maybe a pscheduler to iperf only measurement, with proper archiving from the 
pscheduler host, would help making this a more viable solution.  And probably 
that's what Mark was thinking about.
