a “bottom's up” page of tasks performed while inching towards deployment.

greentail's home directories are now served up on petaltail/swallowtail cluster … this means your home directory is the same across the Dell and HP clusters (minus one host, will work on that tomorrow as well as cluster sharptail).
Weekly refresh of your old home dirs to your new home dirs will continue for another week from now to catch any files created. If you manually need to retrieve files from your old home dir you can do so on host greentail at /oldhomes.
Backup to TSM/Tivoli has been stopped. All backup and restores now rely on the snapshot repository on host greentail at /snapshots/repository …
Matlab and Stata (and queues) have been moved to new greentail cluster. My last “todo”, buying new Intel compilers for cluster greentail, is within sight. The usage of the new HP cluster has been, well, rather low. Not sure why. I am thus proposing a meeting for Q&As about our entire HPC environment detailed at https://dokuwiki.wesleyan.edu/doku.php?id=cluster:95
The following next steps we can also discuss at the meeting:
- virtual tape backups of the old home dirs on petaltail will be halted at some time - hence we will rely on disk2disk backups on greentail (new home dirs with weekly refresh from petaltail) - nodes may disappear on petaltail/sharptail as I experiment with ingestion into greentail
If you can all email me directly with potentially good meeting times, i'll try to maximize attendance.
