OpenACC is an application programming interface (API) for porting code onto accelerators such as GPU and coprocessors. It has been developed by Cray, CAPS, NVidia and PGI. Like in [[OpenMP]], the programmer annotates C, C++ or Fortran code to identify portions that should be parallelized by the compiler. | OpenACC is an application programming interface (API) for porting code onto accelerators such as GPU and coprocessors.
