Low-cpu-load.md

+* Description: A significantly low CPU load, i.e., the number of processes and threads waiting for CPU time, can indicate one of the following:
+  * wrong parallelization settings, defaults, or automatisms in applications for the number of MPI ranks or number of threads
+  * inefficient parallelization of the code or load imbalance between MPI ranks or threads
+  * 
+* Criterion:
+  * CPU load one-minute average is significantly lower than the number of CPU cores or hardware threads allocated by the job on the node
+
+* Works for shared jobs with existing metrics:
+  * yes, if not the load_one is used but the CPU-core-specific cpu_load_core.
+
+* Possible false positives:
+  * 
+
+* Possible Cures:
+  * checking parallelization settings
