 When using a batch script, you have to adapt the partition option within your script: `--partition=dp-dam`
+
+== Persistent Memory ==
+
+Each of the DAM nodes is equipped with [https://www.intel.com/content/www/us/en/architecture-and-technology/optane-dc-persistent-memory.html Intel's Optane DC Persistent Memory Modules] (DCPMM). 
+Whereas the first two nodes (`dp-dam[01,02]`) expose 3 TB of persistent memory the remaining nodes (`dp-dam03-16]`) have 1.5 TB of persistent memory included.
+
+The DCPMMs can be driven in different modes. For further information of the operation modes and how to use them, please refer to the following [https://github.com/pmemhackathon/2019-11-08 information]
+
+DCPMM modes have been added To check which nodes are running in which mode, you can use the `scontrol` command:
+
+{{{
+scontrol show node dp-dam01 | grep AvailableFeatures
+}}}
+
+To select a node using a certain memory mode, you can use the constraint option within SLURM, e.g.:
+
+{{{
+srun -p dp-dam -N 1 -c 24 -t 0:30:0 --constraint=dpcmm_mem --pty /bin/bash
+}}}
