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 now provides the DDT debugger and other Allinea tools for Yellowstone system users, and two training sessions are scheduled for users at the Mesa Lab in Boulder.

The first workshop is on Tuesday, Aug. 26, from 9 a.m. to 4 p.m. in the VisLab. It will be a basic introduction to DDT debugging, using the MAP tool for profiling and optimizing code performance, and generating Performance Reports to summarize the performance of HPC application runs.

Space is limited. Please register here to attend.

A more advanced class is scheduled for Wednesday, Sept. 24. Details will be announced later.

See Running Allinea DDT, MAP and PR jobs to begin using the Allinea tools on Yellowstone.

NCAR’s Mesa Lab in Boulder will be one of several satellite sites for a one-day “Big Data” XSEDE workshop on Tuesday, Sept. 2. The workshop, presented by the Pittsburgh Supercomputing Center, will focus on such topics as the Hadoop system, Spark platform, and Sherlock system.

See the XSEDE User Portal for more information and to register to attend at NCAR or another XSEDE site.

HPSS: Downtime Tuesday, August 19 from 7:00 am - 4:00 pm

No Scheduled Downtime:  Yellowstone, Geyser_Caldera, GLADE

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.

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.

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
