XSEDE HPC Workshop: OpenACC

August 13 and 14, 2013

XSEDE, along with the Pittsburgh Supercomputing Center, the National Institute for Computational Sciences and Georgia Tech will be presenting an OpenACC GPU programming workshop on August 13 and 14.

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 the NSF's premier GPU computing platform,Keeneland, deployed at the National Institute for Computational Sciences.

Due to demand, this workshop will be telecast to several satellite sites. This workshop is NOT available via a webcast. Please note that the hands-on accounts will be limited to 100 students, available across all sites and awarded by order of registration.

You may attend at any of the following sites. Register at https://www.xsede.org/web/xup/course-calendar/-/training-user/class/141.

  • Pittsburgh Supercomputing Center
  • Clemson University
  • University of Connecticut
  • Louisiana State University
  • University of Chicago
  • South Carolina University

The tentative agenda, subject to change, is below. 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.

About Outreach and Training

Workshops incorporate both lectures and extensive hands-on sessions. Programming exercises are carefully designed to reinforce concepts and techniques taught in class.

Instructors have strong scientific and technical backgrounds and are available for individual consultation, including help with participants' own coding needs.

Biomedical Workshops

The education and outreach program of the Biomedical Applications Group includes workshops and online teaching tools, online courses, and workshop webcasts, among other approaches.
