The Daily Bulletin

After several days of intensive work by CISL's Supercomputing Services Group and Consulting Services Group, Cheyenne was released to Accelerated Scientific Discovery (ASD) project users around 9:30 p.m. Wednesday. The teams successfully deployed software to prevent out-of-memory crashes on nodes and a critical update to the PBS Pro scheduler.

CISL will continue to rigorously test the system before it is released to the broader user community. Be sure to watch for updates on Cheyenne's availability in the Daily Bulletin.

NCAR researchers and computational scientists are encouraged to submit requests for NCAR Strategic Capability (NSC) projects to be run on the new 5.34-petaflops Cheyenne system.

The deadline for NSC submissions is March 30. NSC allocations target large-scale projects lasting one year to a few years that align with NCAR’s scientific priorities and strategic plans.

For more information, see the 2017 Call for Proposals from NCAR Researchers for NSC Resources.

Managers, system administrators, user support staff, computational scientists, educators, and students are invited to participate in the 2017 Practice and Experience in Advanced Research Computing conference (PEARC17), which will be held in New Orleans, July 9-13, 2017.

March 6 is the deadline for submitting technical papers and tutorial proposals, and registration is now open. The technical program includes four paper tracks, tutorials, posters, a Visualization Showcase, and Birds of a Feather sessions.

Submissions should emphasize experiences and lessons derived from the use and operation of advanced research computing on campuses or provided for the academic and open science communities. Submissions aligned with the conference theme—Sustainability, Success, and Impact—are particularly encouraged. Details and other deadlines are available in the Call for Participation.

The National Science Foundation (NSF) is requesting input on future science challenges and associated cyberinfrastructure needs. NCAR encourages responses from the community to the Dear Colleague Letter (NSF 17-031, PDF, html) titled “Request for Information (RFI) on Future Needs for Advanced Cyberinfrastructure to Support Science and Engineering Research (NSF CI 2030).”

The NSF announcement said contributions “will be used during the coming year to inform the Foundation's strategy and plans for advanced cyberinfrastructure investments. We invite bold, forward-looking ideas that will provide opportunities to advance the frontiers of science and engineering well into the future.”

The deadline for responding to the RFI is April 5. To provide input into NCAR’s response, please submit suggestions via this form no later than March 22.

The CISL Visitor Program (CVP) is accepting applications until March 3, 2017, for visits occurring between summer 2017 and the following spring. This opportunity seeks to support collaborations between CISL staff and university faculty, practitioners in high-performance computing, new researchers, and students in the atmospheric and related sciences.

Interested candidates should apply only after identifying a CISL staff host and a collaborative activity. The program can provide funding and financially leverage other visitor programs at NCAR for joint collaborative visitors between CISL and other NCAR labs.  Financial support is limited to travel costs and local living expenses. Visits are from two weeks to three months. Longer time periods, such as sabbaticals, are considered on a case-by-case basis.

See for more information.

CISL is now accepting requests from university-based researchers for large-scale allocation requests for the new 5.34-petaflops Cheyenne cluster; submissions are due March 20. The spring opportunity encompasses both university requests for large allocations and Climate Simulation Laboratory (CSL) requests.

The CSL ensures that computing time is available for researchers with extremely demanding, high-profile climate simulations. Typically these require 10 million core-hours or more per year, perhaps for several years, and may produce many terabytes of model output that must be stored for analysis and comparison with other simulations and with observations. See the CSL web page for details.

Large allocations on Cheyenne are those requesting more than 400,000 core-hours. CISL accepts requests from university researchers for these large-scale allocations every six months. For submission instructions and information regarding available resources, see the CISL HPC Allocations Panel (CHAP) page.

Please contact if you have any questions about these two opportunities or need help determining which may be a better fit for your planned computational work.
