How to transfer files to and from our HPC, analysis, and storage systems is now pulled together for easy reference in a new Transferring files documentation section.

In an ongoing effort to help you find the information you need more quickly, we also recently reorganized the documentation menu you will see on that page and many others.

Want to let us know what you think? Look for the "Feedback" link at the very bottom of that new menu.

We look forward to hearing from you.

We are announcing the following opportunity for graduate students and postdoctoral researchers in the atmospheric sciences, applied mathematics or related fields:

Dynamical Core Model Intercomparison Project (DCMIP):

DCMIP Summer School on Future-Generation Non-hydrostatic Weather and Climate Models

Dates: July 30 - August 10,2012


The application period will run from mid February to the end of March, 2012.


This multidisciplinary two-week summer school and model intercomparison project will be held at the National Center for Atmospheric Research from July 30 to August 10, 2012. This summer school brings together graduate students, postdocs, atmospheric modelers, expert lecturers and computer specialists to create a stimulating, unique and hands-on driven learning environment. It will lead to an unprecedented student-run international model intercomparison project, and thereby train the future generation of scientists engaged in global atmospheric model developments. Special attention is paid to the role of emerging non-hydrostatic global atmospheric models.


In particular we focus on atmospheric dynamical cores, which describe the fluid flow component of general circulation models. The summer school and model intercomparison project will `promote active learning, innovation, discovery, mentorship and the integration of science and education. We anticipate testing about 10-12 dynamical cores that represent a broad spectrum of the modeling approaches in the international weather and climate modeling community.

Hosted by: Computational & Information Systems Laboratory National Center for Atmospheric Research (NCAR), Boulder, CO

HPSS archival jobs initially submitted to the archive and share queues, then diverted to the HOLD queue because of project overrun, have been failing due to incorrect queue redirection. The expected net effect of  this change on Monday, February 13, is that HPSS archive jobs will run on the share or archive queue to which they were initially submitted, and users should see expedition of these jobs.

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.

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.

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.
