With recent refinements to the Yellowstone delivery and installation schedule and based on feedback from users, CISL has extended the deadline for University and NCAR Accelerated Scientific Discovery (ASD) submissions to March 5, 2012.

CISL will make dedicated, large-scale resources available on NCAR's forthcoming Yellowstone system from approximately August through October 2012 as part of its ASD initiative for university and NCAR research. Eligible projects may span all of the geosciences and supporting computational sciences.

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 now due March 5, 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 now due on March 5, 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.

Questions on the Yellowstone system, ASD allocations, and the user transition process may be directed to cislhelp@ucar.edu.

NCAR's Computational and Information Systems Laboratory (CISL) invites NSF-supported university researchers in the atmospheric, oceanic, and closely related sciences to submit large allocation requests for the forthcoming petascale Yellowstone system by March 26, 2012.

Revised instructions have been posted for the next round of Large University Allocations, and all requesters are strongly encouraged to review the information on the web site 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 https://www2.cisl.ucar.edu/docs/allocations for more University Community allocation instructions and other allocation opportunities.

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

For the much larger Yellowstone resource, the threshold for Small University Allocations will be 200,000 core-hours, so researchers with such needs can wait until small allocations on Yellowstone become available.

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.

Questions may be addressed to David Hart, User Services Manager, at 303-497-1234 or dhart@ucar.edu.

The Yellowstone system, a 1.5-Pflops HPC system is scheduled to enter production in late summer 2012, and the deadlines to apply for allocations are fast approaching. This session is an opportunity for potential requesters to ask questions about the system, eligibility requirements and writing allocation requests.

Five different opportunities are now or will soon be accepting requests. Details on all of the following opportunities and deadlines are available at https://www2.cisl.ucar.edu/docs/allocations.

* February 20 -- Climate Simulation Laboratory
* March 5 -- Accelerated Scientific Discovery (University and NCAR)
* March 5 -- NCAR Strategic Capability projects
* March 26 -- University (Large requests)
* March 26 -- Wyoming-NCAR Alliance

Starting Thursday, February 2, Mirage nodes 3 and 4 will no longer be available for interactive use. The nodes will be placed under control of the LSF scheduler, to test and configure data analysis and visualization workflows in preparation for the forthcoming Yellowstone environment at NWSC.

The remaining Mirage nodes (0, 1, 2, and 5) will continue to be available for interactive use. These four interactive nodes all have 128 GB to maximize the memory available to Mirage users. CISL is using the Mirage nodes with smaller memory (64 GB) for LSF testing. Please arrange your workflow accordingly.

Contact the Consulting Services Group via cislhelp@ucar.edu if you have comments or questions about this change, or if you are interested in access to the Mirage batch nodes.

The U.S. Global Change Research Program is soliciting proposals for the use of the Climate Simulation Laboratory (CSL) computing facilities, beginning August 1, 2012, and continuing through January 31, 2014. The DEADLINE for submitting proposals is February 20, 2012. If you are currently using the CSL and wish to continue using the facility after June 2012, please submit your renewal proposal and a progress report by the February 20, 2012, deadline.

The multi-agency CSL computing facility was established in 1995 and is dedicated to climate modeling in support of the U.S. Global Change Research Program. The CSL provides high-performance computing and data storage systems to support large-scale, long-running simulations of the Earth’s climate system.

This round of CSL allocations will have access to NCAR’s forthcoming petascale Yellowstone system, a 1.55-PFLOPs IBM iDataPlex cluster, as well as its associated storage, data analysis, and visualization resources. For more information about Yellowstone, see the CISL web site (http://www2.cisl.ucar.edu/). Additional information about use of the CSL and updated submission instructions can be found at the CSL web site, http://www2.cisl.ucar.edu/csl/.

If you have questions about this opportunity, please contact David Hart, User Services Manager, 303-497-1234, or email alloc@ucar.edu.  Please share this information with any other colleagues who might be interested. We look forward to hearing from you.

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.
