Package description

Modules package provides easy and dynamic modification of shell variables adjusting it for the specific requirements of a given software package. For each ot the software packages available on the cluster there is corresponding module defined (or modules if more than one version of the package is available). Name of a module is built according to scheme program-name/version. For libraries the scheme is libs/library-name/version, and for tools (eg. programming languages such as R or Python) tools/library-name/version. For both software packages and libraries, the newest version is default, so the last part version can be omitted. Changes are made using module command and a parameter defining the action.

Frequently used options:

module add <module> or module load <module> – load the program module
module rm <module> or module unload <module> – remove the program module
module list – show list of currently loaded modules
module avail – show list of all available modules
module avail <software_name> – show all versions of given software_name
module purge – remove all loaded modules
module show <module> or module display <module> – show information about given module
module switch <module-1> <module-2> – exchange modules in shell

Examples of use

Load the latest version of Intel compiler

module add intel

Load Intel compiler version 10.0

module add intel/10.0

List all available versions of Intel compilers

module avail intel

Exchange OpenMPI Ethernet version for the Infiniband version

module switch openmpi/1.4.3-intel-11.1-eth openmpi/1.4.3-intel-11.1-ib

Remove paths of the Intel compiler version 10.0 from the environment

module rm intel/10.0

Using your own modules (Advanced)

Modules package allows creating your own modules also. To do that you need to load first the module use.own. It will create library privatemodules in your home directory. In this directory all own modules should be placed. The modules program will automatically check new installed modules and add them to the available list. New modules can use TCL language functions. You can get more information about creating modules on the project site.
