The following is a hands-on introduction to Futhark through a collection of commented programs, listed in roughly increasing order of complexity. You can load the programs into the interpreter to experiment with them. For a conventional introduction to the language, Parallel Programming in Futhark may be a better choice. For more examples, you can check our implemented benchmarks . We also maintain a list of projects using Futhark .
Some of the example programs use directives for plotting or rendering graphics.
Literate Futhark allows direct use of gnuplot . These examples show simple and common cases.
The following examples are ported from Dex , a dependently typed functional array language that uses a somewhat different approach to describing loop processing. We've tried to keep the original naming scheme and programming style.
The majority of written Futhark code is probably still Futhark’s own test and benchmark suites. However, there are some programs that have been written in Futhark because it was a good tool for the job, and not just to test the compiler. A possibly incomplete list:
Diving Beet is a falling sand game, which is a kind of simple particle simulator toy. Its main purpose is to produce pretty effects. There is a blog post with details and a video.
