## Install behavior

- Post-install hook: not defined
- Caveats: By default, compiled Chapel programs will be single-locale only. To compile and run multi-locale Chapel programs locally: Compile your program with: `chpl --comm=gasnet --comm-substrate=udp` And then run it with: `chplrun-udp ./your_program_name` To simulate GPU execution, you can compile your program with: `chpl --locale-model=gpu --gpu=cpu`
- Bottle: available on arm64_linux, arm64_sequoia, arm64_sonoma, arm64_tahoe, sonoma, x86_64_linux

## Project history and usage

Chapel is a parallel programming language and compiler toolchain for productive computing at scale, designed for laptops, clusters, cloud systems, GPUs, and supercomputers.

### Project history

Chapel was developed as a high-performance parallel programming language, historically associated with Cray and now maintained openly under the chapel-lang organization. The official README describes a portable language intended for CPUs and GPUs from desktops to supercomputers.

### Adoption history

Chapel moved from an HPC research language into a routinely released open-source language runtime and compiler. The GitHub release stream shows semiannual 1.x releases by 2014 and quarterly-style 2.x releases by 2024-2026, while the supplied package facts show distribution through Homebrew, Fedora/DNF, and MacPorts.

### How it is used

Users compile Chapel programs with `chpl`; the Homebrew package also installs developer tools such as `chpldoc`, `chplcheck`, `chpl-language-server`, and Mason, Chapel's package/build tool.

### Why package nerds care

Chapel matters to package nerds because it is a full language distribution rather than a single utility: compiler, runtime, language server, documentation generator, package tooling, and configuration-file discovery all arrive through a package-manager install.

### Timeline

- 2014: chapel-lang/chapel public GitHub repository created and 1.10.0 GitHub release published.
- 2015: 1.11.0 and 1.12.0 releases continued the regular open release cadence.
- 2024: Chapel 2.x release series was underway.
- 2026: Chapel 2.9.0 released as the Summer 2026 release.

### Related projects

- Mason is Chapel's package/build tool and is installed with the Homebrew formula.
- The Chapel project is listed by its README alongside the High Performance Software Foundation and Linux Foundation branding.
