OpenACC GPU Programming Workshop

Event Date: 

Tuesday, January 15, 2013 - 10:00am to Wednesday, January 16, 2013 - 4:00pm



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 January 15 and 16, 2013.

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 University of Iowa plans to be a satellite site for this program. Presentations will be via video conferencing in 2520-C University Capitol Centre.

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

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.
