Advancing the state-of-the-art in high-performance computing,
communications and data analytics.

October 16 & 17, 2012

The Pittsburgh Supercomputing Center, the National Institute for Computational Sciences and Georgia Tech, in partnership with Internet2, will present an OpenACC GPU programming workshop on October 16 and 17.

Based on demand, we will present this workshop at 10 satellite sites.

OpenACC is the accepted standard using compiler directives to allow quick development of GPU capable codes using standard languages and compilers. It has been used with great success to accelerate real applications within very short development periods. This workshop assumes knowledge of either C or Fortran programming. It will have a hands-on component using Keeneland, an XSEDE resource deployed at the National Institute for Computational Sciences. Keeneland is the NSF's premier GPU resource.

The agenda is below. It is designed as two short days to be time-zone friendly.

You may attend at any of the following sites. Register by following the link for your preferred location. Please note that the hands-on accounts will be limited to 100 students, available across all sites and awarded by order of registration.

XSEDE, the Extreme Science and Engineering Discovery Environment, is the most advanced, powerful, and robust collection of integrated digital resources and services in the world. It is a single virtual system that scientists and researchers can use to interactively share computing resources, data, and expertise. XSEDE integrates the resources and services, makes them easier to use, and helps more people use them.
