Export variables to worker processes

Description

Sends R objects from the master process to all worker processes.

Usage

Rhpc_Export(cl, variableNames,
            usequote = ifelse(is.logical(getOption("Rhpc.usequote")),
                              getOption("Rhpc.usequote"), TRUE),
            pos = 1,
            envir = as.environment(pos))

Arguments

cl	external pointer to MPI communicator
variableNames	character vector of object names to export
usequote	logical; if FALSE, quote handling is skipped for performance improvement
pos	environment position from which to retrieve objects (default: global environment)
envir	environment from which to retrieve objects (default: environment at position pos)

Details

This function retrieves objects from the master's environment and sends them to all worker processes, making them available in the workers' global environment.

Objects are sent via collective communication.
