Many hands make light work, or so they say. So do many cores, many threads and many data points when addressed by a single computing instruction. Parallel programming – writing code that breaks down computing problems into small parts that run in unison – has always been a challenge. Since 2011, OpenACC has been gradually making it easier. OpenACC is a de facto standard set of parallel extensions to Fortran, C and C++ designed to enable portable parallel programming across a variety of computing platforms.
