Guy Steele's talk came up here: https://news.ycombinator.com/item?id=30462835 with an APL solution of: +/((⌽⌈\⌽a)⌊⌈\a)-a
with comment that it could "be fully parallelizable and run fast on the GPU, as it's based on a couple scan (generalized prefix sum) operations". Some explanation in my reply there. |
