 There is node local storage available for the DEEP-EST DAM node (2 x 1.5 TB NVMe SSD), but configuration is to be done for those devices.

 == Multi-node Jobs ==
 
+Currently, multi-node MPI jobs are possible on the DAM only by modifying the environment in the following way:
 
+{{{
+$ ml Intel ParaStationMPI
+$ env LD_LIBRARY_PATH=/opt/parastation/lib64:/opt/extoll/x86_64/lib/:${LD_LIBRARY_PATH} PSP_TCP=0 PSP_OPENIB=0 PSP_EXTOLL=1 srun -p dp-dam -N 2 -n 2 ./MPI_HelloWorld
+Hello World from processor dp-dam02, rank 1 out of 2 
+Hello World from processor dp-dam01, rank 0 out of 2 
+}}}
+
+**Attention:** This is a temporary workaround.

 **Attention:** Since the Extoll network is not in place yet multi-node MPI Jobs are currently disabled.
