mirai: Minimalist Async Evaluation Framework for R

Designed for simplicity, a 'mirai' evaluates an R expression asynchronously in a parallel process, locally or distributed over the network. Modern networking and concurrency, built on 'nanonext' and 'NNG' (Nanomsg Next Gen), ensures reliable and efficient scheduling over fast inter-process communications or TCP/IP secured by TLS. Distributed computing can launch remote resources via SSH or cluster managers. A queued architecture readily handles more tasks than available processes, requiring no storage on the file system. Innovative features include event-driven promises, asynchronous parallel map, and automatic serialization of otherwise non-exportable reference objects.
