1. /cat/proc/cpuinfo Some of my sytems will fall back to a slower CPU speed if they crash under certain circumstances. This makes them a lot slower, but the only indication other than speed is that the MHz number in cpuinfo changes. To recover from this on these systems one must go into the BIOS and manually reset the CPU speed. 2. Check CPU power management and verify that if it is on it isn't locked into the lowest power state. 3. ethtool eth0 #or eth1, as appropriate for your system Verify that the NIC parameters are all as expected. 4. ifconfig eth0 Look for errors, dropped, overruns, etc. Regards, David Mathog mat...@caltech.edu Manager, Sequence Analysis Facility, Biology Division, Caltech _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
