NCAR users attending the American Meteorological Society (AMS) meeting in New Orleans, January 24-25, have several opportunities to learn more about NCAR's forthcoming data-centric Yellowstone environment.

CISL will host a Yellowstone Allocations Briefing on Tuesday (Jan. 24) at 4:30 p.m. at the Hilton New Orleans Riverside in Salon D21/24. During this session, David Hart, CISL's User Services manager, will describe Yellowstone, the various allocations opportunities, and tips for writing successful allocation requests. Light hors d'oeuvres will be served.

In addition, Hart will be at the NCAR booth (#316) to showcase the Yellowstone system and be on hand to answer user questions. Presentations are scheduled for Tuesday (Jan. 24) at 11 a.m. and 3 p.m. and again on Wednesday (Jan. 25) at 10:30 a.m. and 1:30 p.m.

The Yellowstone environment at NWSC will greatly expand the opportunities for researchers in the geosciences and related fields. For more details, see https://www2.cisl.ucar.edu/resources/yellowstone

An installation issue was discovered in the previously installed version of netcdf-4.1.3 (only the netcdf-4.1.3_mpi version was affected, the netcdf-4.1.3_seq and netcdf-3 format versions were not affected and were not changed). The issue prevented MPI programs to correctly execute netcdf-4.1.3 distributed code.

We have fixed this issue, deleting and recreating /contrib/netcdf/4.1.3_mpi/

Netcdf-4.1.3_mpi is now linked to hdf5-1.8.6_mpi and not hdf5-1.8.6_seq, fully providing parallel functionalities.

If you had problems running netcdf-4.1.3_mpi previously, please try again.

Please send questions and reports of problems to cislhelp@ucar.edu.

/blhome under Bluefire has been available for you to copy any of your files for a little over a month.  We plan to decommission this old home area on Tuesday, December 13. We ask you to copy any of the files from /blhome before it is decommissioned.

UPDATE: We're reposting this announcement to highlight a clarification to the ASD eligibility requirements posted online. Eligible projects may span all of the geosciences and supporting computational sciences. 

 

CISL is pleased to announce the availability of dedicated, large-scale resources on NCAR's recently announced Yellowstone system from approximately May through July 2012 as part of its Accelerated Scientific Discovery (ASD) initiative for university and NCAR research.

NSF-supported university researchers interested in applying for ASD computational resources can view eligibility and proposal requirements at: https://www2.cisl.ucar.edu/docs/allocations/asd. Applications are due January 13, 2012.

NCAR researchers interested in applying for ASD computational resources may view eligibility and proposal requirements at: https://www2.cisl.ucar.edu/docs/allocations/2012nsc/instructions. NCAR ASD projects will be chosen from submissions for NCAR Strategic Capability (NSC) projects, also due on January 13, 2012.

The Yellowstone system will be a 1.6-petaflops IBM iDataPlex cluster with 74,592 Intel Sandy Bridge EP cores, 149.2 TB of memory, and 11 PB of parallel disk storage. Yellowstone is expected to deliver nearly 30 times the capacity of NCAR's current Bluefire system.

NCAR users attending the American Geophysical Union (AGU) Fall Meeting in San Francisco, Calif., next week, are encouraged to stop by the NCAR booth (#1222) to learn more about our forthcoming data-centric Yellowstone environment.

Davide Del Vento, one of CISL's HPC consultants, will showcase the Yellowstone system and be on hand to answer user questions. Presentations are scheduled for Wednesday (Dec. 7) and Thursday (Dec. 8) at 11 a.m. and 3 p.m. both days.

The Yellowstone environment at NWSC will greatly expand the opportunities for researchers in the geosciences and related fields. The new system will have more than 600 million core-hours available for allocation each year.

Dec. 8, 2011

CISL Help Desk will be unable to assist walk-ins on Wednesday, December 4.
The Help Desk team and HPC Consultants will be on duty, and users may continue to send
email to cislhelp@ucar.edu or call 303-497-2400. Your questions will be addressed as soon as possible.

Yellowstone Briefing
FL2 Large Auditorium (1022) or via Webcast
November 29, 2011 @ 2 p.m. MST

In concert with the Unidata Seminar Series, CISL presented a briefing on the Yellowstone system, NCAR's forthcoming data-intensive petascale environment, November 29, 2011, at 2 p.m. MST in the NCAR Foothills-2 Large Auditorium (1022) or via Webcast at  http://www.fin.ucar.edu/it/mms/fl-live.htm. The briefing discussed the Yellowstone hardware, including the disk resource and data analysis and visualization clusters, the software environment, and the allocations opportunities available to the various user communities.

The event was webcast and recorded for those unable to attend in person.

NCAR will continue to offer several allocations opportunities, the first of which will be for the Accelerated Scientific Discovery (ASD) period. A small number of large-scale, fast-turnaround projects in the geosciences will be selected for early, priority access from May-July 2012. The submission deadline for ASD projects will be January 13, 2012.

Yellowstone will be the inaugural computing resource at the NCAR-Wyoming Supercomputing Center (NWSC) in Cheyenne, Wyoming. Yellowstone will be a 1.6-petaflops IBM iDataPlex cluster with 74,592 processor cores and 149.2 TB of memory. The Yellowstone environment at NWSC will greatly expand the opportunities for researchers in the geosciences, with more than 600 million core-hours available each year.

NCAR has announced that IBM will install a massive central file and data storage system, a petascale high-performance computational cluster, and a system for visualizing the data at the new NCAR-Wyoming Supercomputing Center (NWSC). Equipment delivery will commence in early 2012, with production computing operations planned for summer 2012.

The new system, named Yellowstone, and its data-centric supercomputing environment will be the NWSC's inaugural system. Yellowstone is expected to deliver 1.6 petaflops peak computing performance and provide nearly 30 times the computational performance of Bluefire. Yellowstone will be accompanied by a nearly 11-petabyte disk system.
