User documentation for the PLEIADES cluster at the University of Wuppertal
Our centrally provided software installations are offered through modules.
The LMod
command module
is used to make certain programs in a specific version available to your current shell.
For example, to load a GCC 10.3.0:
$ module spider GCC/10.3.0
--------------------------------------------
GCC: GCC/10.3.0
--------------------------------------------
Description:
The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages (libstdc++, libgcj,...).
You will need to load all module(s) on any one of the lines below before the "GCC/10.3.0" module is available to load.
2021a
[...]
$ module load 2021a GCC/10.3.0
$ gcc --version
gcc (GCC) 10.3.0

Notice the “2021a” module.
We use a hierarchical module naming scheme, which means that modules only become available, if their dependencies are loaded.
The 2021a module serves as an entry point into a software stack with a collection of many programs in a certain version.
A more recent entry module, e.g. 2022a, is likely to contain more recent versions of the software.
module spider
will find any version available and using it with name/version
will tell you exactly how to load the program.

On our cluster, we have the following storage systems:
/tmp
: 2TB of fast SSD storage per node. Great place for active work directories in jobs./beegfs
: >900TB shared storage accessible in all nodes. Home directory to all users and intended for storing results and organizing data. I/O intensive jobs should avoid on interacting directly with /beegfs
./cvmfs
: Read-only storage to distribute special software./common/home
: Home directory for users of the whep groupFor more information, please consult our file system documentation.
