Recent Changes
- Modules will be required to select MPI and other software environments on the Opteron systems.
- Job priorities are now calculated by factoring a user's project allocation, the job's size, the time it has been in the queue, how large it is, and where it is to run. The relative priorities of pending jobs may be viewed with the sprio command.
- Please do not build codes with the -qipa, -O4, or -O5 flags in GPFS space. This triggers a known deadlock in GPFS.
Availability CCNI will have down time scheduled every two weeks on Tuesday starting May 20, 2008. These outages will begin at 0800 hours Eastern time and end by the end of business the same day. These outages will be at the discretion of the CCNI support staff and will generally not require the entire alloted time. These events will also facilitate any extremely large benchmark type runs that may have accumulated for any of the systems. For example, if you have a job queued for the entire Blue Gene and the job has not been run due to scheduling difficulty the job will be run either just before or just after the maintenance window.
