This is a draft of the `tractor` way to implement the example from the "processs pool" in the stdlib's `concurrent.futures` docs: https://docs.python.org/3/library/concurrent.futures.html#processpoolexecutor-example Our runtime is of course slower to startup but once up we of course get the same performance, this confirms that we need to focus some effort not on warm up and teardown times. The mp forkserver method definitely improves startup delay; rolling our own will likely be a good hot spot to play with. What's really nice is our implementation is done in approx 10th the code ;) Also, do we want offer and interface that yields results as they arrive? Relates to #175 |

tractor
A structured concurrent, async-native "actor model" built on trio and multiprocessing.
tractor is an attempt to bring trionic structured concurrency to distributed multi-core Python; it aims to be the Python multi-processing framework you always wanted.
tractor lets you spawn trio "actors": processes which each run a trio scheduled task tree (also known as an async sandwich). Actors communicate by exchanging asynchronous messages and avoid sharing any state. This model allows for highly distributed software architecture which works just as well on multiple cores as it does over many hosts.
The first step to grok tractor is to get the basics of trio down. A great place to start is the trio docs and this blog post.

pip install git+git://github.com/goodboy/tractor.gitFeel like saying hi?
This project is very much coupled to the ongoing development of trio (i.e. tractor gets most of its ideas from that brilliant community). If you want to help, have suggestions or just want to say hi, please feel free to reach us on in our matrix channel. If matrix seems too hip, we're also mostly all in the the trio gitter channel!
