Software on JURECA

Access to installed software on JURECA is organized through a hierarchy of modules.

• Show what modules are compatible available to load right now (given the toolchain modules you have already loaded):

  module avail

• Load a specific version of a module

  module load <modulename>/<moduleversion>

• List what modules are currently loaded

  module list

• Unload a module

  module unload <modulename>/<moduleversion>

• Unload all modules

  module purge

• Find the location of a module within the module hierarchy

  module spider <modulename>

• Show how to load NetCDF:

  module -r spider '.*netCDF.*'

Module Stages

• On JURECA there are major software updates every 6 month (in May and November).
  

  These updates are called stages.
  

  New stages require that user applications are recompiled.
  
  To use "old" executables without recompiling or to create executables with older compiler versions, old stages can be loaded with:

  module use /usr/local/software/jureca/OtherStages
  module load Stages/xxx

  e.g. : load old intel compiler with parastation MPI and netcdf:

  module purge       
  module use /usr/local/software/jureca/OtherStages   
  module avail
  module load Stages/2018b
  module load intel-para
  module load netCDF-Fortran
