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*
*closeAllConnections()*
*rm(list=ls())*
*# Adjust environment variables*
*Sys.setenv(PATH="/usr/local/openmpi-1.4.5-tm/bin:/usr/local/openmpi-1.4.5-tm/include:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/maui/sbin:/usr/local/maui/bin")*
*Sys.setenv(LD_LIBRARY_PATH="/usr/lib64/R/lib:/lib:/usr/local/lib64:/usr/lib/jvm/jre/lib/amd64/server:/usr/lib/jvm/jre/lib/amd64:/usr/lib/jvm/java/lib/amd64:/usr/java/packages/lib/amd64:/lib:/usr/lib:/usr/local/openmpi-1.4.5-tm/lib/:/usr/local/opemmpi-1.4.5/lib:")*
*Sys.setenv(LD_PRELOAD="/usr/lib64/libutil.so")*
*# Install Package*
*install.packages("Rmpi", configure.args = c*
* (*
*
"--with-Rmpi-include=/usr/local/openmpi-1.4.5-tm/include/",*
* "--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*
*library(Rmpi)*
The package installed without problems, but when loading it the error below
occursr:
*** building package indices
** testing if installed package can be loaded
* DONE (Rmpi)
The downloaded source packages are in ‘/tmp/RtmpVk8euT/downloaded_packages’
> # Load Package
