+## Debugging on VSC-4
+
+Currently (6.2021) there is no development queue on VSC-4 and the support suggested to do the following:
+
+```bash
+# Request resources from slurm (-N 1, a full Node)
+salloc -N 1 -p mem_0384 --qos p71386_0384 --no-shell
+# Once the node is assigned / job is running
+# Check with
+squeue -u $USER
+# connect to the Node with ssh
+ssh [Node]
+# test and debug the model there.
+```
