GLADE home directories backed up, but not other file spaces

February 24, 2012

CISL daily backs up the files in your personal /glade/home file space, but that is not the case in other GLADE directories you might be using.

For details on our backup and purge policies, please review our newly revised GLADE File System documentation. Be sure to take a look at our new Transferring files documentation, too.

Let us know what you think. We look forward to hearing from you.

New web page consolidates file transfer procedures

February 21, 2012

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.

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

February 21, 2012


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.

Deadline: March 26, Large university requests for computing resources at NCAR

February 16, 2012

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 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 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

Bluefire netcdf-4.1.3_mpi Correction

January 10, 2012

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

Help Desk / Consulting Services will close early Monday, December 31 at 1:30pm

January 2, 2013

The help-desk/consulting office will close early today at 1:30pm in order for staff to begin the holiday.

Computing users may still submit tickets to and we will respond by Wednesday, January 2.
