Contents for pacman
Start Time: 06/20/2013 -- 09:00 End Time: 06/20/2013 -- 14:00 Reason: The Pacman system vendor, Penguin Computing, has issued a kernel update needing to be deployed on the Pacman system as soon as possible to correct instability issues affecting the pacman 4 core nodes. A reservation has been made on the system to keep jobs queued with walltimes extending beyond Thursday at 9am. User jobs running past Thursday at 9am will be killed at that time.
Start Time: 05/18/2013 -- 12:00 End Time: 05/30/2013 -- 12:00 Reason: University FAST power outage and OS upgrade to RHEL 6.4. Default modules will be updated. *** Recompiling of user code required. *** If users wish to recompile your pacman code in the RHEL 6.4 environment prior to the May 18th scheduled downtime, please log onto pacman14.arsc.edu and recompile using the software available via modules and /usr/local/pkg. If users would like to submit batch jobs in the RHEL 6.4 environment prior to the scheduled downtime, please contact the ARSC Help Desk. *** Update on May 24, 2013 *** The OS upgrade is taking longer than first anticipated. Therefore, the pacman.arsc.edu scheduled downtime has been extended through May 30th. Files on $CENTER and $ARCHIVE are accessible via logins to fish.arsc.edu. Files on $HOME are available via the linux workstations on /pachome/$HOME. The names of the linux workstations are available on http://www.arsc.edu/arsc/resources/linuxws/index.xml
