 The HLRN-III provides a brief online documentation for '''alinea''' (see https://www.hlrn.de/home/view/System3/AllineaDDT for details).
+
+
+== How to check the memory usage of a run ==
+
+Checking the memory usage might be interesting for large jobs, especially in case you experience problems with it.
+
+How to:
+
+ 1. Login to login node (e.g. blogin1)
+ 2. ssh bxcmom0{1..4}   --> choose from 1-4
+ 3. module load nodehealth
+ 4. xtnodestat | grep <your HLRN username>
+ 5. pcmd -a <apid> 'ps -u nikfarah -o pid,time,cmd,rss,vsize,pmem'  --> apid is the  application process id given by the command in 4.
