Modules System
A lot of different compilers, MPI implementations, tools, and ISV software are installed on the RWTH Compute Cluster. To handle the different requirements of each piece of software we provide a module system, which allows the user to easily load the needed software and/or switch between its different versions. All necessary search paths and environment variables are set by loading a module. The modules package is available for the ksh, zsh, and tcsh shells. Please note: Users of the bash shell have to add the line
. /usr/local_host/etc/bashrc |
to their ~/.bashrc file in order to activate the modules package.
Commands
Command | Description |
|---|---|
module list | List all loaded modules. |
module avail | List all available modules. |
module load [modulename] | Load a software. |
module unload [modulename] | Unloaded a software. |
module switch [oldmodule] [newmodule] | Exchange a module. Some modules depend on each other (i.e. MPI modules depends on the loaded compiler.) |
module reload | Reload all modules. This may fix your environment, especially if you use a NX session. |
module apropos [modulename] | Find out in which category a module is. |
module whatis [modulename] | Print some information about the module. |
All modules are organized in categories. Because of that you might first have to load a specific category before you are able to load modules contained inside it. For example:
$ module avail ------------ /usr/local_rwth/modules/modulefiles/linux/x86-64/DEVELOP ------------ acumem/1.0.6 openmpi/1.5.1mt acumem/2009.2(default) openmpi/1.5.3mt acumem/2010.3 pgi/10.5 ddt/2.5 pgi/10.9 ddt/2.6(default) pgi/11.1(default) gcc/4.3 python/2.4.2 gcc/4.5 python/2.4.6 gcc/system-default(default) python/2.5.2(default) intel/11.1(default) python/2.5.5 intel/11.1.073 python/2.6.6 intel/12 python/2.7.1 ... ... ------------ /usr/local_rwth/modules/modulefiles/GLOBAL ------------ BETA DEPRECATED GRAPHICS MATH TECHNICS CHEMISTRY DEVELOP LIBRARIES MISC UNITE |
If you want to use python 2.7.1, for example, you need to do the following:
$ module load DEVELOP $ module load python/2.7.1 |
