For me it shows: Linux version 2.6.18-128.el5 (mockbu...@builder10.centos.org) I am a bit confused with the numbering scheme, now. Is this older or newer than Craigs? You are right Craig, I haven't noticed any random slowdowns but my data is statistically sparse. I only have a single Nehalem+CentOS test node right now. -- Rahul _______________________________________________ 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
