Greetings NERSC PVP User, Last weeks, /tmp on Killeen was successfully expanded to over 330GB. I would like to extend our sincere gratitude to those users who reduced their usage of /tmp prior to the change; it really helped us minimize the cluster-wide downtime. As a result of this change, we have increased the per-process and per-request disk space limits for the st_80 and st_256 batch queues on Killeen to 40GB. This is double the previous limit, but is still only half the limit on the batch-only machines. Because interactive work tends to use significant amounts of /tmp, we will closely monitor the impact of this batch system change. Users can help us maintain a flexible, usable I/O environment on Killeen by actively managing their file usage in /tmp. Files that will not be accessed for a couple days should be stored in HPSS and then removed from /tmp. As always, our goal is to provide a lifetime of at least 14 days for files in /tmp. Best regards, David Turner User Services Group email: dpturner@nersc.gov NERSC Division phone: (510) 486-4027 Lawrence Berkeley Lab fax: (510) 486-7520
