+## Memory Consumption of a Job
+
+If you are only interested in the maximal memory consumption of your job, you don't need profiling
+at all. This information can be retrieved from within [job files](slurm.md#batch-jobs) as follows:
+
+```bash
+#!/bin/bash
+
+#SBATCH [...]
+
+module purge
+module load [...]
+
+srun a.exe
+
+# Retrieve max. memory for this job for all nodes
+srun max_mem.sh
+```
+
+The script `max_mem.sh` is:
+
+```bash
+#!/bin/bash
+
+echo -n "$(hostname): "
+cat /sys/fs/cgroup/memory/slurm/uid_${SLURM_JOB_UID}/job_${SLURM_JOB_ID}/memory.max_usage_in_bytes
+```
+
+!!! note
+
+  * Make sure that the script `max_mem.sh` is executable (e.g., `chmod +x max_mem.sh`) and add the
+    path to this script if it is not within the same directory.
+  * The `srun` command is necessary to gather the max. memory from all nodes within this job.
+    Otherwise, you would only get the data from one node.
