An optimising compiler for a functional, array-oriented language.

Futhark is a small programming language designed to be compiled to efficient parallel code. It is a statically typed, data-parallel, and purely functional array language in the ML family, and comes with a heavily optimising ahead-of-time compiler that presently generates GPU code via CUDA and OpenCL, although the language itself is hardware-agnostic.

For more information, see the website at https://futhark-lang.org

For introductionary information about hacking on the Futhark compiler, see the hacking guide. Regarding the internal design of the compiler, the following modules make good starting points:

• Futhark contains a basic architectural overview of the compiler.

• Futhark.IR.Syntax explains the basic design of the intermediate representation (IR).

• Futhark.Construct explains how to write code that manipulates and creates AST fragments.

The Futhark Programming Language

Futhark is a purely functional data-parallel programming language in the ML family. It can be compiled to typically very efficient parallel code, running on either a CPU or GPU. The language is developed at DIKU at the University of Copenhagen, originally as part of the HIPERFIT centre. It is quite stable and suitable for practical programming.
