5 sourcesHarlan: a Language That Simplifies GPU Programming
1 points · Open discussionI really should update the user guide, since the language has changed a lot in the last year.
I have an earlier post that discusses a couple of the optimizations that Harlan does: http://blog.theincredibleholk.org/blog/2013/06/10/some-simpl...
To me the win for Harlan over CUDA is its region system, which lets you work with more intricate pointer structures in the GPU. For example, there is an interpreter for the Lambda Calculus as one of the test cases, which would be much harder to do in straight CUDA: https://github.com/eholk/harlan/blob/master/test/lambda3.kfc
Very soon, Harlan will have support for higher order procedures, which is also not available in CUDA.
In Harlan, new Lispy language for GPU programmingPretty cool, region inference is handled via miniKanren, a relational / constraint logic programming embedding in Scheme (also available in Clojure as core.logic):
