We have been using 10g CX4 for the past 7yrs for our cluster core network and are just going fully into 10gT. But our focus is more on bandwidth/HTC instead of HPC, i.e. we do not care so much about latencies.
I'm sorry if I was unclear: I'm interested specifically in whether recent developments change the basic 10G picture. we have cx4 as well, and lots of IB, but all our 10g is oldish stuff. I guess I'm kind of hoping to hear that switch, nic, driver improvements have changed the picture from years ago, when the best you could do with 10g was ~7 us
latency.
Do you have any particular tests in mind, we can certainly look into it and report back on our findings.
min packet ping-pong latency is the standard metric, though packets/sec rate might be interesting as well. thanks, mark hahn. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
