[intrepid-notify] ALCF Weekly Updates | September 27, 2013

[ALCF User Services]

*** Server Maintenance Brings Possible Outages 9/28 ***
Maintenance occurring on servers Saturday, September 28, may result in outages between 8 a.m. – 8 p.m. for the ALCF website. Support tickets and mailing list communications may also be delayed.

*** Get Faster Throughput with prod-short, prod-capability Job Queues ***
Mira and Intrepid users, if you have a small job (4096 nodes or fewer) that is long, consider breaking it up into a series of two or more shorter jobs each depending on the prior job. Small jobs that are short (six hours or less) are eligible to run in more areas of the machine than small jobs that are long, (more than six hours), and will get through the queue faster. Mira users, see http://www.alcf.anl.gov/user-guides/job-scheduling-policy-bgq-systems for job information. Intrepid users, visit: http://www.alcf.anl.gov/user-guides/job-scheduling-policy-bgp-systems for details. Please contact support at alcf.anl.gov with any questions.
