In this video from the Nvidia booth at SC13, Michael Wolfe presents on OpenACC. “The OpenACC API provides a high-level, performance portable programming mechanism for parallel programming accelerated nodes. Learn about the latest additions to the OpenACC specification, and see the PGI Accelerator compilers in action targeting the fastest NVIDIA GPUs.”
Open ACC version 2.0 is using enhanced data management capabilities in its quest to become the de facto standard for directive-based accelerators programming in C/C++ and Fortran.
