 The software made available on the new stack via Easybuild is arranged hierarchically, with only some core modules made available to the user at login. Typically, these core modules include the compilers, or some other standalone tools (i.e. JUBE). Loading such core modules via `module load` allows the list of available modules to increase, including the modules that are installed with the fore-mentioned core module as a dependency.

+== Machine Learning Software ==
+
+In preparation for the deployment of the cluster module, a new software stack compiled for Skylake is being installed on the system. Machine Learning software is available on this stack. This Skylake stack can be enabled with the following commands:
+
+{{{#!sh
+ml purge
+ml unuse $MODULEPATH
+ml use /usr/local/software/skylake/Stages/2018b/UI/Tools/
+ml use /usr/local/software/skylake/Stages/2018b/UI/Compilers/
+ml Intel
+}}}
+
+This stack is also managed with Easybuild and is hierarchically structured.
+
+This stack is currently under development: please use `ml spider` after enabling this stack to check the status of the software installed on it.
+
+
+== Using the old stack ==
+
+Currently, the Easybuild stack is the default one. To use the old stack available before the transition to Easybuild, the users can use the following command:
+
+`enable_old_stack`
+
+If the old stack is needed in a batch script, the alias given above does not work. To circumvent this issue, please add the following lines to your script:
+
+{{{#!sh
+ml purge
+unset MODULEPATH

+=== Compilers (relevant for old stack only!)===
 
 There are several compilers available, but as it is highly recommended to use the Intel compiler on the KNC system it might be best to also use it on the DEEP system.\\
