The Chapel Parallel Programming Language

Notes on Chapel Downloads

Chapel is supported on Cray systems (e.g., Cray XC™, Cray XE™, Cray XK™, Cray CS™) and is also portable to most UNIX-based parallel platforms (commodity-based clusters or systems from other HPC vendors) as well as desktops/laptops running UNIX, Mac OS X, or Windows with Cygwin. Users have also reported successful executions of Chapel on cloud-based computing systems. More detailed notes on prerequisites for using Chapel are also available.

Please note that Chapel is a work-in-progress, with all that implies in terms of stability and performance. We are interested in receiving constructive feedback on the Chapel language and compiler, with the goal of improving its utility to and adoption by the parallel programming community.
