Parallel Execution

The FORK cluster and functions depending solely on forking (e.g., mcparallel) are not supported by the GraalVM R engine at the moment. One can use the PSOCK cluster, which should work in the same way on GraalVM R engine as in GNU-R.

Moreover, FastR can be used as a worker node in a PSOCK cluster computation driven from GNU-R. See FastRCluter package for GNU-R, which provides helper functions to create PSOCK cluster nodes that run GraalVM R engine.
