very light-weight cooperative concurrency?

[Marko Schütz-Schmuck]

Looking at Erlang's actors, Go's goroutines, Boost coroutines, Protothreads and other implementations of cooperative concurrency, I was wondering what has been done in this direction in ATS. What I found so far is only https://bluishcoder.co.nz/2012/07/19/lightweight-tasks-library-for-ats.html. Since this uses ucontext it is not as light-weight as I was imagining. I would assume that this task library could be modified to use sigsetjmp/siglongjmp.

What experiences have others made or what approaches have others pursued?

Not much that I am aware of in this direction.

If you just want to use cooperative threads in ATS, then the simplest way is probably

to make up an interface in ATS for Boost coroutines or protothreads.

Because ATS can be compiled to Erlang via atscc2erl, it makes sense to use Erlang's

actors as well.

If you know how your application is supposed to use cooperative threads, then implementing

one based on setjmp/longjmp should be pretty quick. And it can be a lot of fun as well.

Or, you could try to write your code in the continuation-passing style :)

I had no idea. :-)

Here's a good read: http://arxiv.org/abs/1603.03727 (I think HX won't post it out of modesty. :-))
