Hello Guys

I installed a Cluster with OpenMPI with support to TORQUE in a CENTOS 6,
tested it with 1 master and two slaves and cluster works fine.

Installed R and RStudio and executed the code below, an error occurred when
trying to load package, somebody can help, please ?

*# Clean environment*

*# Adjust environment variables*

*# Install Package*
*install.packages("Rmpi", configure.args = c*
*                 (*
*                  "--with-Rmpi-libpath=/usr/local/openmpi-1.4.5-tm/lib/", *
*                  "--with-Rmpi-type=OPENMPI",*
*                  "--with-mpi=/usr/local/openmpi-1.4.5-tm/"*
*                 )*
*                )*

*# Load Package*

The package installed without problems, but when loading it the error below

*** building package indices
** testing if installed package can be loaded
* DONE (Rmpi)

The downloaded source packages are in ‘/tmp/RtmpVk8euT/downloaded_packages’
> # Load Package
> library(Rmpi)
Error : .onLoad failed in loadNamespace() to 'Rmpi', details:

  error: impossíble load object shared

Erro: package or namespace load failed for ‘Rmpi’*
