Cray T3E Operating System Upgrade
The operating system on the NSC T3E will be upgraded during
the regular maintenance slot Monday May 3, 07:00-09:00.
Please note that jobs that are running will be left running when the
queues are closed. This schedule only concerns NEW jobs. On
Monday morning 07:00 all jobs still running will be killed.
- The system will be unavailable during this time.
- We will not be able to checkpoint jobs before the upgrade and restart
them under the new operating system. The queue system will therefore
not accept new jobs according to the following schedule:
Queue name Closing time Reopen time
All long queues Friday April 30, 17.00 Monday May 3, 9.00
All short queues Sunday May 2, 17.00 Monday May 3, 9.00
Test queues will remain open
The OS upgrade is from Unicos/mk 2.0.3 to 2.0.4 which will fix
some bugs and enable some new features, among them the ability
to run single PE jobs on an application PE. More information on
this and other new features in 2.0.4 will be supplied
at a later date.
