Chapel (programming language)

<p>Chapel, the Cascade High Productivity Language, is a <a href="/facts/Parallel_programming_language/nQzcpzQt">parallel programming language</a> that was developed by <a href="/facts/Cray/coAlupuy">Cray</a>, and later by <a href="/facts/Hewlett_Packard_Enterprise/d9NbClDt">Hewlett Packard Enterprise</a> which acquired Cray. It was being developed as part of the Cray Cascade project, a participant in <a href="/facts/DARPA/Uf9sarhT">DARPA</a>'s <a href="/facts/High_Productivity_Computing_Systems/q057kEmI">High Productivity Computing Systems</a> (HPCS) program, which had the goal of increasing <a href="/facts/Supercomputer/HT9NwGAN">supercomputer</a> productivity by 2010. It is being developed as an <a href="/facts/Open-source_software/HzTaB8E9">open source</a> project, under version 2 of the <a href="/facts/Apache_license/5AeIjas8">Apache license</a>.
</p><p>The Chapel compiler is written in <a href="/facts/C_(programming_language)/Ky2No763">C</a> and <a href="/facts/C%252B%252B/Et0F2qn9">C++</a> (<a href="/facts/C%252B%252B14/CXukL6pA">C++14</a>). The backend (i.e. the optimizer) is <a href="/facts/LLVM/nPmcspQN">LLVM</a>, written in C++. Python 3.7 or newer is required for some optional components such Chapel’s test system and c2chapel, a tool to generate C <a href="/facts/Language_binding/V5HW4Wr4">bindings</a> for Chapel. By default Chapel compiles to binary executables, but it can also compile to C code, and then LLVM is not used. Chapel code can be compiled to libraries to be callable from C, or Fortran or e.g. Python also supported. Chapel supports <a href="/facts/General-purpose_computing_on_graphics_processing_units/roBwsPY2">GPU programming</a> through code generation for NVIDIA and AMD graphics processing units.
