Thomas Leonard did a great talk on our experiences with effects at the OCaml Workshop this year: https://watch.ocaml.org/videos/watch/74ece0a8-380f-4e2a-bef5... Also you can start playing with effects today using

Multicore upstreaming wasn't blocked on having fully-fledged effects. If you look at the diff between multicore 5.00 and trunk OCaml, the changes required for fibers is pretty small relative to the multicore GC and making the rest of t

Yes, it's announcing that the next but one version, 5.0, will support multicore and effect handlers. For what it's worth you can actually start using Multicore OCaml today, there are installation instructions on the wiki: https:&

Our paper from ICFP last year has extensive benchmarks against stock OCaml: https://arxiv.org/abs/2004.11663 In short there should be very little performance difference against stock. As KC has linked in a sibling comm

Not sure I have enough of an overview to comment on that in general, unfortunately. The overview Anil gave at the end of last year on the OCaml Platform should give you an idea of the many other strands of work that are going on: https:&#x

Good questions! 1) As I mentioned in https://news.ycombinator.com/item?id=27142502 there is support for parallelism and concurrency. Giving an example of where these might be useful in a webservice. The addition of shared-m

Yes, arm64 support is non-functional but we're planning to get it back in to a working state very soon.

Not dumb questions at all. Multicore adds parallelism via Domains (which are essentially heavyweight threads) and concurrency via Effects and fibers. There's a multicore GC that supports both of those. We plan to upstream things in two

As the sibling comment mentions, the hard part is actually retrofitting multicore whilst maintaining compatibility _and_ performance. Our paper last year covers most of why this is tricky: https://arxiv.org/abs/2004.116

Multicore is almost entirely backwards compatible with stock OCaml. One issue is C libraries that use so-called naked pointers but these are discouraged anyway and 4.12 ships a detector to find these: https://discuss.ocaml.org&#x

Was this the paper? https://www.repository.cam.ac.uk/bitstream/handle/1810/28323... Effects that 'interrupt' a fiber are asynchronous effects. They can be used to implement schedulers and the like.

I'm not aware of large standalone projects that depend solely on it. Multicore is backwards compatible with stock OCaml though and 4.12 ships with some stub Atomics ( https://github.com/ocaml/ocaml/blob/4.

It's pretty close. There have been PRs landing to close the gap with Multicore for a couple of releases now. You should see an OCaml 5.0 branch (which brings parallelism via Domains) in the next couple of months. The time between that

Unfortunately some of this information is out of date and refers to Multicore with the concurrent minor collector - a collector we don't plan to upstream. We plan to upstream the parallel minor collector, which has a shared minor heap
