I don't see how people should glorify this with the word "algorithm". It is a trivial undergrad homework exercise, once you give the hint "use parallel reduce / fold / prefixsum".
This may involve more interesting tradeoffs if you deal with large or sparse matrices or matrix-free operators.
- dang 3y agoIf you know more than others do, that's great, but instead of posting putdowns, please share some of what you know so the rest of us can learn. The trouble with comments like this is that they degrade discussion put others down without really teaching us anything. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sort=byDate&type=comment&query=share%20know%20learn%20by:dang https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor... https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html
