:boom::computer::boom: A data-parallel functional programming language

The Futhark Programming Language

Futhark is a purely functional data-parallel programming language. Its optimising compiler is able to compile it to typically very performant GPU code. The language and compiler is developed at DIKU at the University of Copenhagen, originally as part of the HIPERFIT centre. The language and compiler is quite stable, and suitable for practical programming.

For more information, see the website.

Also see the compiler and language documentation and the basis library documentation.

Installation instructions here.

Usage

To compile a Futhark program to sequential C:

futhark c prog.fut -o prog

Or maybe OpenCL:

futhark opencl prog.fut -o prog

And then run it:

./prog < prog.input

To interpret a Futhark program:

futhark run prog.fut < prog.input

Hacking

We try to make use of Github issues for organising our work. Issues tagged with good first issue do not require deep knowledge of the code base.

Testing

Run futhark test tests to check how well we're doing. Use futhark test -t if you're in a hurry and only want to check that all the tests type-check.
