Description
{{{name}}} website
R is a free software environment for statistical computing and graphics.
Template:App Location
Available versions
Note: File a support ticket to request installation of additional libraries.
- 2.13.1
- 2.14.1
- 2.14.1-mpi - R base package MPI-enabled via the Rmpi library.
- 2.14.2 (default)
Running the application using modules
To use R with the environment modules system at HPC the following commands are available:
Get module information for r:
$module spider R
Load the default application module:
$module load R
The modulefile for this software adds the directory with executable files to the shell execution PATH and sets the following environment variables:
- HPC_R_DIR - directory where R is located.
- HPC_R_BIN - executable directory
- HPC_R_LIB - library directory
- HPC_R_INCLUDE - includes directory
To use the version of R built for parallel execution with MPI via the Rmpi library load the following modules:
module load intel/11.1 openmpi/1.4.3 R

mpi.spawn.Rslaves()
- In case R exits unexpectedly, have it automatically clean up
- resources taken up by Rmpi (slaves, memory, etc...)
