Getting Started: Software & File Systems

Available Software

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.

File Systems

On our cluster, we have the following storage systems:

• Workernode local storage in /tmp: 2TB of fast SSD storage per node. Great place for active work directories in jobs.
• BeeGFS in /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 in /cvmfs: Read-only storage to distribute special software.
• NFS in /common/home: Home directory for users of the whep group

For more information, please consult our file system documentation.
