Description #
Chapel (Cascade High Productivity Language) is a parallel programming language designed for high-performance computing and scalable distributed systems. It aims to make parallel programming more productive and accessible.
History #
Chapel was initiated in 2004 by Cray Inc. as part of the DARPA High Productivity Computing Systems (HPCS) program. It has since evolved as an open-source language maintained by the Chapel team at Hewlett Packard Enterprise. Chapel was designed to support both local and distributed parallelism with a strong focus on productivity.
