 **Raw Usage** tabs are expected to show 100% core usage if processes perform one task of pure computation. If tasks are distributed over, 2, 3, or 4 CPUs, the raw usage will be 200%, 300%, or 400%, respectively. **% Allocated** tabs rescale raw usage values relative to the number of CPUs that are set with the `cpus` directive. If the `cpus` directive is not set, CPUs are set to `1` and **% Allocated** tabs will show the same values **Raw Usage** tabs.
