On our clusters, the default shell is Bash. With the operation system, a list of basic tools (mainly command line tools) are provided, including editors, file analyzing and manipulation tools, packing and transfer tools etc. This commands are accessible all the time, on all nodes.

Other software packages (libraries and applications) are available via the LMOD (lua modules) modules. By the help of this tool a lot of different packages even in different versions can be provided, without unwanted influences. These software packages are installed based on users requests, by using the Spack software management tool, when possible.
