I haven’t tested it yet, but looks very interesting. I was looking into running multi-core logic in the browser recently, and have the emscripten pthreads examples working fine, but it requires allowing shared-array-buffer, which kind of opens up spectre / all the speculation bugs, perhaps a bit more than necessary (and it’s only available behind flags atm).
I was thinking perhaps someone would’ve used BEAM with message passing between Web Workers rather than shared memory, to get scalability without opening up bugs in the hardware architecture. But seems this hasn’t really caught on properly yet.
There was discussion about a rust rewrite in 2017 Redirecting to Google Groups
i’m happy someone is working on it at least
