sprint: Overview of SPRINT
In sprint: Simple Parallel R INTerface

SPRINT (Simple Parallel R INTerface) is a parallel framework for R. It provides a High Performance Computing (HPC) harness which allow R scripts to run on HPC clusters. SPRINT contains a library of selected R functions that have been parallelized. Functions are named after the original R function with the added prefix 'p', i.e. the parallel version of cor() in SPRINT is called pcor(). These parallelized functions are written in C and MPI. Call to these functions are included directly in standard R scripts.

The following functions are implemented in SPRINT 1.5.0: - papply - pboot - pcor - pmaxT - ppam - prandomForest - pRP - pstringdistmatrix - pterminate - ptest

See the User Guide and Release Notes in the sprint folder or the SPRINT web page at http://www.r-sprint.org for more information.

To make use of SPRINT it is necessary to include the library first. Then include calls to the SPRINT functions you want to use. It is also necessary to exit SPRINT using the pterminate function which shutdown MPI as well as SPRINT.
