i didn't specifically time it, so my "few seconds" might be inline with your .5 second > Either way, with 60s time scales and ibacm so broken it fails instantly > I suspect you have some hostname/dns/tcp-ip-on-eth or other fundamental > problem somewhere. it's certainly possible. unfortunately the documentation is lacking and no one on the ofa list wants to help and i don't have time to trounce through source code to figure out what's going on. at some point i'll figure it. but clearly something is wonky, at least i can set aside the hardware aspect for now. thanks _______________________________________________ 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
