In this video, Bronson Messer from ORNL presents: An Introduction to OpenACC. “OpenACC is gaining momentum and adoption,” said Duncan Poole, President of the OpenACC Standards Group. “Developers benefit because using OpenACC directives makes parallel programming more productive and collaboration easier. Large, legacy codes are easier to maintain and accelerated code is more portable across HPC systems.”

Video: An Introduction to OpenACC

“The OpenACC Application Program Interface describes a collection of compiler directives to specify loops and regions of code in standard C, C++ and Fortran to be offloaded from a host CPU to an attached accelerator. OpenACC is designed for portability across operating systems, host CPUs, and a wide range of accelerators, including APUs, GPUs, and many-core coprocessors.”
