domainslib - Parallel Programming over Multicore OCaml

domainslib provides control and data structure for parallel programming using domains.

The supported data structures are:

Channels
- Channels may be shared between multiple senders and receivers.
- Channels ensure FIFO message order.
- Channels come in two flavours -- bounded (fixed-buffer size (>= 0) beyond which the send blocks) and unbounded.
Task
- Work-stealing task pool with async/await parallelism and parallel for loop.

See examples for usage.

Installation

The library can be installed using multicore-opam, an OPAM repository of multicore specific packages.

$ opam switch create 4.12.0+domains+effects
$ opam install domainslib

If you are interested in hacking on the implementation, then opam pin this repository:

First install the multicore compiler and dune:

$ opam switch create 4.12.0+domains+effects
$ opam install dune

Then, pin a clone of this repo:

$ git clone https://github.com/ocaml-multicore/domainslib
$ cd domainslib
$ opam pin add domainslib file://`pwd`
