Interactive jobs can be requested by using salloc and specifying the respective options on the command line. The following will give you an interactive shell on one node for one hour: salloc -N 1 --partition=singlenode --time=01:00:00 The following will give you four nodes with an interactive shell on the first node for one hour: salloc -N 4 --partition=multinode --time=01:00:00 Settings from the calling shell (e.g. loaded module paths) will be inherited by the interactive job! This and more information can be found in our documentation on Fritz.
