Docker and parallel builds

I was listening to an interesting talk from Laura Frank from Codeship. In case you build or maintain a Continuous {Integration, Delivery} environment this definitely worth watching and they describe how they used LXC and now Docker to build their CI/CD infrastructure.

TL;DR

Interesting to me, the description in the YAML file reminded me quickly on a course I needed to pass during my study in parallel computing. The exam had one section where you had to describe parallel and sequential processes with some high level constructs. You had to describe a given time sequence graph for processes on n processors with the primitives BEGIN/END for sequential parts and COBEGIN/COEND for parallel processes.
