aiida-core uses plumpy as its workflow backend and uses circus to daemonize its workflow manager process. However, the plumpy workflow library, and the circus process & socket manager have not kept up with recent developments, forcing libraries of AiiDA ecosystem to run with outdated versions of tornado, and making it incompatible with the latest python web technology. In this project, I will replace tornado dependencies of plumpy and aiida-core by asyncio to enable full support of asyncio in aiida-core. If the goals and deliverables are reached before the end of the project, I will also migrate circus, which is also used by many other open-source projects besides AiiDA, from tornado to asyncio.
