12834 :: Parallelism in Nim

• TKD (orginal) [2025-04-26T07:22:27+02:00] view original

  What is the status of parallelism in Nim?

  I ask because I would like to begin developing a performant linear algebra library including iterative solvers, which I want to be parallelised from the start.

  For example, am I correct in thinking that the parallel statement is being deprecated?

  For an introduction, see my Malebolgia project.

  Thanks for this , Araq.

  I was aware of these libraries but they seem to be abandoned?!. Hence, one of the reasons for my question on the topic.

  All the linear algebra libraries I have seen are also single-threaded except for Arraymancer, but it is not a linear algebra library in the usual sense.

  I will look at using malebolgia as it seems reasonably straightforward.

  I don't think they're abandoned in the sense that if you open an issue / find a bug or create a PR, it's likely you'll get an answer. It's just that the author don't necessarily have anything left to add.
