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

CISL has scheduled an extended downtime for the High Performance Storage System (HPSS) — from 7 a.m. to 11 a.m. Tuesday, Sept. 16 — to prepare for the fall Mesa Lab shutdown on Saturday, Oct. 11. Information on the potential impact of the October shutdown on HPSS and other systems that CISL manages will be published as details become available.

This class is now full, but due to demand we expect to offer it again.

The CISL Consulting Services Group (CSG) will present the training course “Python for Scientists” from 9 a.m. to 4 p.m. Thursday, August 21. Participants in this hands-on class will learn about the Python programming language and the tools and modules that are most useful to scientists, including IPython, IPython Notebook, NumPy, matplotlib, mpi4py, and others.

Participants can attend in person at the VisLab in NCAR’S Mesa Lab in Boulder, or remotely via webcast. See the Python for Scientists course page for more information.

Brent Leback, PGI Applications & Service Manager for NVIDIA (which recently acquired PGI), will present “deep-dive” PGI compiler classes on OpenACC and CUDA Fortran on Aug. 19 and 20, at the NCAR Mesa Lab in Boulder. Both classes will be in the Main Seminar Room.

The OpenACC class is scheduled for 9 a.m. to 4 p.m. Tuesday, Aug. 19. Topics will include an introduction to accelerated computing, parallel and loop directives, kernels constructs, data directives and lifetimes, optimization strategies, CUDA-like interoperability, and others.

The CUDA Fortran class is scheduled for 9 a.m. to 4 p.m. Wednesday, Aug. 20. Topics will include an introduction to CUDA Fortran (CUF), CUF kernels, compilation, profiling, debugging, optimization strategies, OpenACC interoperability, managed data, and more.

Leback has worked in various positions over the past 30 years in HPC customer support, math library development, applications engineering, and consulting at QTC, Axian, PGI, STMicroelectronics, and now NVIDIA. Until recently he managed the compiler group at PGI.

CISL has updated the default Python core language to v 2.7.7 and also updated a number of Python modules and libraries so the latest versions are the defaults in the Yellowstone environment.

Upgrades included installation of the latest NumPy (v 1.8.1), SciPy (v 0.14.0), matplotlib (v 1.3.1), IPython (v 2.1.0), and many others. The latest IPython package, in particular, has many new features for parallel programming and several enhancements to IPython Notebook. See IPython to learn about using IPython on Yellowstone.
