What is User Environment Modules?
Taken from Environment Modules Project
The Environment Modules package provides for the dynamic modification of a user’s environment via modulefiles.
Each modulefile contains the information needed to configure the shell for an application. Once the Modules package is initialized, the environment can be modified on a per-module basis using the module command which interprets modulefiles. Typically modulefiles instruct the module command to alter or set shell environment variables such as PATH, MANPATH, etc. modulefiles may be shared by many users on a system and users may have their own collection to supplement or replace the shared modulefiles.
Step 1: Download the modules packages
Download the latest modules packages from Modules Sourceforge Project Site.
Step 2: Download the dependencies tcl and tcl-devel
# yum install tcl tcl-devel
Step 3: Unpacked, Configure and Install
# tar -zxvf modules-3.2.9c.tar.gz
Go to the Modules folder ($ModuleHome)
# cd modules-3.2.9
I wanted to keep all my individual modules files at /usr/local/Modules/contents. You can keep module files anywhere you wish to keep.
# ./configure --with-module-path=/usr/local/Modules/contents
Make and install the configuration
# make && make install
Step 4: Amend .modulefiles
Edit . modules to let Modules know where all the customized module files will be kept
# vim /usr/local/Modules/3.2.9/init/.modulespath
Comment out all the lines except the directory where all the customised modules files will be kept.
..... ..... /usr/local/Modules/contents # General module files ..... .....
Step 5: Update /etc/profile.d of the Servers
Copy the profile.modules from the $ModuleHome Directory
# cp /$ModuleHome/modules-3.2.9/etc/global/profile.modules /etc/profile.d/modules.sh
The content of modules.sh are as followed
#----------------------------------------------------------------------# # system-wide profile.modules # # Initialize modules for all sh-derivative shells # #----------------------------------------------------------------------# trap "" 1 2 3 case "$0" in -bash|bash|*/bash) . /usr/local/Modules/default/init/bash ;; -ksh|ksh|*/ksh) . /usr/local/Modules/default/init/ksh ;; -zsh|zsh|*/zsh) . /usr/local/Modules/default/init/zsh ;; *) . /usr/local/Modules/default/init/sh ;; # sh and default for scripts esac trap 1 2 3
Sample Installation of an application using Modules (Intel Compilers)
Step 1: Create a Module File.
Place the Module File for Intel in /usr/local/Modules/contents
a. Create an Intel Folder inside /usr/local/Modules/contents
# mkdir /usr/local/Modules/intel
b. Create a module file for the version of Intel (In my case, “12.0.2”). To save some time, you can copy a “sample” file and you can edit
# cp $ModuleHome/modules-3.2.9/modulefiles/modulefile /usr/local/Modules/contents/intel/12.0.2
# vim /usr/local/Modules/contents/intel/12.0.2
#%Module1.0
proc ModulesHelp { } {
global version prefix
puts stderr "\tIntel XE 12.0.2 (icc, icpc, ifort)"
}
module-whatis "Intel XE 12.0.2 (icc, icpc, ifort)"
prepend-path PATH /opt/intel/composerxe/bin
prepend-path LIBRARY_PATH /opt/intel/composerxe/lib/intel64
prepend-path LD_LIBRARY_PATH /opt/intel/composerxe/lib/intel64:/opt/intel/mkl/10.2.6.038/lib/em64t
prepend-path MANPATH /opt/intel/composerxe/man
prepend-path MKL_HOME /opt/intel/mkl/10.2.6.038
setenv CC icc
setenv CXX icpc
setenv FC ifort
setenv F77 ifort
setenv F90 ifort
Step 2: Setting the Default versions of Intel.
If you have different version of software you wish to present to the users, do the following
# vim /usr/local/Modules/contents/intel/.version
#%Module1.0 set ModuleVersion "12.0.2"
