CISL has scheduled an “Advanced Usage of Allinea Tools” class on Wednesday, Sept. 24, from 9 a.m. to 4 p.m. in the VisLab at the NCAR Mesa Lab in Boulder. The class will provide a quick review of Allinea DDT and MAP core features and then provide hands-on exercises using advanced and additional features and concepts that were not covered in the introductory course in August.  

A significant portion of the day will be dedicated to using DDT and MAP to review or find issues in participants’ own codes. Participants who have specific bug or performance issues will have an opportunity to share their display via overhead projector and work as a class to find resolutions.

If you have not worked with Allinea tools or did not attend the basic class in August, log in to Yellowstone and work through the self-guided tutorial materials in /glade/u/home/paisley/demo_package/ before attending the advanced class. Also see Running Allinea DDT, MAP and PR jobs to begin using the Allinea tools on Yellowstone.

Space is limited. Please register here to attend.

CISL is offering a one-hour class and webcast at 10 a.m. Wednesday, Sept. 17, to help users get the most from their High Performance Storage System (HPSS) allocations. The class will be in the VisLab at the NCAR Mesa Lab in Boulder.

Erich Thanhardt of CISL’s Mass Storage Systems Group will give participants a look “under the hood” of HPSS and review best practices and procedures for using the system, where allocations are made and charged in terms of terabyte-years. Topics will include deciding when data should (and should not) be archived to HPSS; how to archive large data sets most efficiently; and how best to retrieve files from the system.

Deadline September 15, 2014, for large university requests for NCAR computing resources

NCAR's Computational and Information Systems Laboratory (CISL) invites NSF-supported university researchers in the atmospheric, oceanic, and related sciences to submit large allocation requests for the Yellowstone system by September 15, 2014. All requesters are strongly encouraged to review the instructions at https://www2.cisl.ucar.edu/chap before preparing their submissions.

For the Yellowstone system, computational requests greater than 200,000 core-hours are considered "large." Smaller requests for up to 200,000 core-hours are accepted any time and are typically reviewed within two business days; visit the allocations web page for details.

The large requests will be reviewed by the CISL High-performance computing Allocations Panel (CHAP), and there must be a direct linkage between the researcher's NSF award and the computational research being proposed. Visit http://www2.cisl.ucar.edu/docs/allocations/university for more university allocation instructions and opportunities.

Allocations will be made on Yellowstone, NCAR's 1.5-petaflops IBM iDataPlex system, the data analysis and visualization clusters (Geyser and Caldera), the 11-PB GLADE disk resource, and the HPSS archive. See https://www2.cisl.ucar.edu/resources/yellowstone for more system details.

Questions may be addressed to: David Hart, User Services Manager, 303-497-1234 alloc@ucar.edu
