Deadline September 15, 2014, for large university requests for NCAR computing resources

NCAR's Computational and Information Systems Laboratory (CISL) invites NSF-supported university researchers in the atmospheric, oceanic, and related sciences to submit large allocation requests for the Yellowstone system by September 15, 2014. All requesters are strongly encouraged to review the instructions at https://www2.cisl.ucar.edu/chap before preparing their submissions.

For the Yellowstone system, computational requests greater than 200,000 core-hours are considered "large." Smaller requests for up to 200,000 core-hours are accepted any time and are typically reviewed within two business days; visit the allocations web page for details.

The large requests will be reviewed by the CISL High-performance computing Allocations Panel (CHAP), and there must be a direct linkage between the researcher's NSF award and the computational research being proposed. Visit http://www2.cisl.ucar.edu/docs/allocations/university for more university allocation instructions and opportunities.

Allocations will be made on Yellowstone, NCAR's 1.5-petaflops IBM iDataPlex system, the data analysis and visualization clusters (Geyser and Caldera), the 11-PB GLADE disk resource, and the HPSS archive. See https://www2.cisl.ucar.edu/resources/yellowstone for more system details.

Questions may be addressed to: David Hart, User Services Manager, 303-497-1234 alloc@ucar.edu

HPSS: Downtime Tuesday, July 29, 7:00am - 11:00am

No Scheduled Downtime:  Yellowstone, Geyser_Caldera, GLADE

Tue, 07/15/2014

Users of CISL’s High Performance Storage System (HPSS) can expect improved system response soon, as the installation of new “D” drives nears completion and the migration of data from B-tapes winds down in the next few weeks. System bandwidth will increase significantly.

The system presently is being pushed continuously at near capacity and some users have encountered unexpected errors and delays as a result of tape library problems that have since been addressed.

Please review our Use and storage policies and other HPSS documentation to learn about how to use the system most efficiently.

About the CISL Daily Bulletin

The Daily Bulletin is published by the Computational and Informational Systems Laboratory of the National Center for Atmospheric Research. The Daily Bulletin (or “Daily B”) is a newsletter of system news, changes to the CISL environment, and reminders of the regularly scheduled maintenance periods for major CISL resources. You can read the Daily Bulletin in your email, or on the web.

All new CISL user accounts (i.e., [your UCAR username]@ucar.edu) are subscribed automatically to the Daily B mailing list. You can change your Daily B preferences, subscribe, or unsubscribe online.
