Hi all I have succesfully installed a 20 node cluster using OSCAR-1.4b11 and RedHat-7.3. Everything works superficially (builtin tests for PBS, MAUI, etc work), except for something which i can't understand. Ganglia only seems to see nodes as up if I dump traffic onto the network, ie if tcpdump -i eth1 (server cluster NIC) is running. as soon as tcpdump is turned off, nodes start to die. At first, we were using a 3com superstack, which had fancy onboard software, and we thought we were filtering the multicast packets which comprised the ganglia signal, but now we have a surecom switch, which has no onboard software and we see the same problem. Well, one difference is that with the 3Com, we couldn't collect MAC adresses (step 4) while with the surecom we can.
Any ideas as to why ganglia is acting the way she does ? thanks a lot, -- Bruce Becker, PhD student - Department of Physics University of Cape Town Room 405, R.W.
