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 forthcoming petascale Yellowstone system by September 17, 2012. Revised instructions have been posted for the next round of Large University Allocations, and all requesters are strongly encouraged to review the instructions before preparing their submissions.

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

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

For the much larger Yellowstone resource, the threshold for Small University Allocations has been increased to 200,000 core-hours; researchers with smaller-scale needs should wait until CISL begins accepting small allocation requests in September. However, university researchers with NSF awards can apply for a Small University Allocation on Bluefire or Janus to obtain information on the resource requirements for their research and to test the computational efficiency of their code before applying for a Yellowstone allocation.

 The consulting walk-in service will be closed on June 29 AM in order to allow consulting staff members to attend SEA townhall meeting invited by NCAR director. We will respond to the tickets submitted in our ExtraView system before and after this meeting as usual. We apologize for any inconvenience caused by this closure.

Boulder County lifted the pre-evacuation order for the Table Mesa area yesterday evening, and UCAR planned a delayed opening for this morning, with staff able to return to the Mesa Lab at 10 a.m.
CISL operations staff were granted early access and began bringing up Bluefire, GLADE, Mirage/Storm, and HPSS at around 9 a.m. Most systems are expected to be up by 10 a.m., though Bluefire may take slightly longer to restart. A Notifier message will go out as each system becomes available.
Once restarted, CISL staff and systems will return to normal operations mode.

Video and slide presentations from the CISL Consulting Services Group’s May 2012 HPC workshop are now available online. They include materials from workshop sessions on Fortran, UNIX, and parallel programming with MPI and OpenMP, and introductions to IDL, Matlab, and NCL. The presentations can be found in the Training section of the CISL web site.

Training OpportunitiesWays to build or refresh your HPC skills will be easy to identify with the addition of a new “Training Opportunities” button on CISL end-user documentation web pages.

The orange button appears on the right side of your screen when there are training materials from NCAR, XSEDE, or HPC University that relate to a page’s content. Just click the button to see a list of the courses.

Give it a try by looking at our Yellowstone Software page, for example.

Let us know what you think. We appreciate your feedback.

The Mesa Lab is closed all day today, June 27, to all staff other than critical operations staff due to the Flagstaff Fire west of Boulder. Because even these last few staff will have to leave immediately if a mandatory evacuation is ordered, Bluefire and the other CISL systems will remain down until operations staff are able to safely return. 

The Flagstaff Fire started yesterday afternoon, spreading rapidly and leading UCAR to issue an informal evacuation of NCAR's Mesa Lab. To enable operations staff to leave, CISL shut down all of its major systems, including Bluefire, at 4 p.m. June 26.

UCAR and local fire officials will continue to evaluate the fire situation. CISL will provide further updates about the status of Bluefire and other systems via the Notifier service.

CISL Help Desk and Consulting staff are working remotely today. Users may call 303-497-2400 or email cislhelp@ucar.edu with any questions.
