OpenACC

OpenACC is a directive-based parallel programming model for C, C++, and Fortran.

It is most often associated with directive-based programming for GPU computers,

but has also been used for programming multi-core CPUs and FPGAs. OpenACC is

developed and maintained by members of the OpenACC standard organization.
