This documentation is for an old GraalVM version. See the latest version.

Parallel Execution

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

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