-====== Checkpointing & Restarting Jobs ======
-===== Motivation & Introduction =====
-Introducing wall times is one measure to ensure balanced distribution of resources on every HPC cluster. Yet, some applications need to have extremely long run times. The solution is [[https://en.wikipedia.org/wiki/Application_checkpointing|Application Checkpointing]], where a snapshot of the running application is saved in pre-defined intervals.
-<WRAP center round info 95%>
-We want to provide integrated checkpointing with slurm, eventually. Until then only third party tools are offered without additional documentation from our part.
-</WRAP>
-===== Third party tools =====
-==== Checkpointing multithreaded applications with dmtcp ====
-[[http://dmtcp.sourceforge.net/index.html|dmtcp]] is a versatile checkpointing application providing a good documentation (incl. a video).
-We provide at least one module for dmtcp, check:
-<code bash>
-tools/DMTCP/2.4.5
