The following projects have documentation on this wiki:

• Power Aware Cluster
• OPT Cluster (includes Otto, a more modern 8-core 32GB compute node.)
• Symmetric Multi-Threading Cluster
• NetApp Storage Array

Forgot to mention this earlier. SMT nodes are now being reserved on a long-term per-node basis, and they're tracked on the SMT Reservations wiki page.

The backup system has been documented. If you have large and/or unimportant files that don't need to be backed up, please read up how to exclude them…it's really quite simple. Let me know if you have any questions or comments.

I rebuilt the wiki's keyword index, so the search function should work properly now. Also, you can add the wiki to your Firefox search bar. — Tyler Bletsch

All PAC nodes are available now. The hard disks on PAC00, 03, 06, and 08 have been replaced. All the nodes have new kernel with 2.6.17. Note that the PAC09 consumes identical power as others because the video card was eliminated.

Our power meter deployment was rearranged as planned. 10 meters are distributed into both PAC and OPT clusters. For detailed information, please follow this link
