Chapel (programming language)

Chapel, whose name expands to Cascade High Productivity Language, is an open source programming language first created in 2004. The Programming Language Database credits its design to David Callahan, Hans Zima, Brad Chamberlain and John Plevyak, and records that early development took place at Cray Inc. It was built as a parallel programming language within the Cray Cascade project, a participant in DARPA's High Productivity Computing Systems program, whose goal was to raise supercomputer productivity by the year 2010. The language is released under version 2 of the Apache license. The same page lists Python, ZPL, Ada, C#, Java, Fortran, C++ and UPC as influences on its design, and notes that Chapel compiles to C and that its implementation is written in Chapel, C++, C and other languages. Its listed features include static typing, type inference, generics, iterators, records, operator overloading and modules.
