Description #
Chapel is a parallel programming language developed for high-performance computing applications. It aims to improve programmer productivity while enabling efficient use of large-scale parallel machines.
History #
Chapel was created by Cray Inc. as part of the DARPA High Productivity Computing Systems program, first released in 2009. It targets scientific computing, enabling scalable parallelism with a simple syntax inspired by imperative and object-oriented languages.

Fun Facts #
- Chapel was developed to bridge the gap between low-level parallel programming and high productivity.
- It supports locales, abstracting different memory and processor spaces.
- Chapel programs can run on supercomputers with thousands of cores.
- The language includes automatic data distribution for parallel arrays.
- Cray donated Chapel to the open-source community in 2017.
