OpenACC: Difference between revisions

OpenACC makes it relatively easy to offload vectorized code to accelerators (like GPUs, for example). Unlike [[CUDA]] and OpenCL where kernels need to be coded explicitly, OpenACC minimizes the amount of modifications to do on a serial or [[OpenMP]] code. The compiler converts the OpenACC code into a binary executable that can make use of accelerators. The performance of OpenACC codes can be similar to the one of a [[CUDA]] code, except that OpenACC requires less code development.
