hack_parallel

Parallel and shared memory library
README

This library contains the core parallel and shared memory components used in Hack, Flow, and Pyre.
The internals of these components are little known outside of these projects, yet stand to benefit the OCaml community more generally, both
for practical use and educational purposes.

This library extracts the core components, wraps them in a tidier interface, and builds with dune. It is a personal best effort
and offered 'as-is': there is no promise of maintenance, and no official support or affiliation with the projects and/or companies
supporting the projects above.

The code contains potentially leftover and irrelevant functions (again, best effort), and do not necessarily have the most recent upstream changes of corresponding modules. This is especially the case for
modules in procs and heap (cf. respective procs and heap in Hack). Pull requests for
upstream changes to these files are welcome. The files in the current library are current as of around mid-2018.

Install and Example

Simply:

git clone https://github.com/rvantonder/hack-parallel.git && cd hack-parallel && make && make install

please see the example project here to get a feel for the interface: https://github.com/rvantonder/hack-parallel-example

Some more details

The design decisions behind the parallel architecture and shared memory are best explained by this video
and this part of the documentation.
You can ignore the scary THIS CODE ONLY WORKS WITH HACK--the code does work generally, but you have to keep in mind the
restrictions on memory operations as explained in the rest of the file. The motivation behind the shared memory implementation is similar to ancient.
