pony_lua_parallel

using Pony to parallelize a single threaded C program (Lua)

Building and Running

Docker

docker-compose build --build-arg MAX_NUM=40

re-run:

docker-compose run -e MAX_NUM=40 pony

Pony

• Install Pony
• ponyc
• run pony_lua_parallel

CI

• Travis-CI runs on 1 virtual core, thus parallelism effects cannot be observed there.

Can't have --ponymaxthreads > physical cores, the number of threads you'd be running with (2 > 1)

• Appveyor seems to run on more than 1 core, and thus some parallelism can be observed

Contents

See main.pony:

• synchronous_demo: calling Lua synchronously from Pony via FFI
• asynchronous_demo: creating an actor owning a Lua instance upon each request, and waiting for asynchronously arriving results via Promises
• lua_sending_messages_demo: creating a fixed number of worker actors in Pony, and dispatching work to them from Lua
• lua.pony: the problem-specific FFI based Lua 5.3 wrapper class
