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', ensures reliable scheduling over fast inter-process communications or TCP/IP secured by TLS. Launch remote resources via SSH or cluster managers for distributed computing. The queued architecture scales efficiently to millions of tasks over thousands of connections, requiring no storage on the file system. Innovative features include event-driven promises, asynchronous parallel map, and seamless serialization of otherwise non-exportable reference objects.

Notes

For local mirai requests, the default transport for inter-process communications is platform-dependent: abstract Unix domain sockets on Linux, Unix domain sockets on MacOS, Solaris and other POSIX platforms, and named pipes on Windows.

This may be overriden, if desired, by specifying 'url' in the daemons() interface and launching daemons using launch_local().
