Scalability Graph for CPU Count Usage
- Red-shaded area, this site is hurting your program's performance. Remove or significantly modify the site annotations.
- Yellow-shaded area, this site is helping your program's performance, but maybe the gain may not be enough to justify the effort you needed to refactor and maintain your program. You should investigate how the results can be improved. Also, it might be more energy (power) efficient to increase the serial throughput using program changes or faster processors (parallel machines are designed to run at a lower clock frequency than certain serial machines).
- Green-shaded area, this indicates good results. If you can achieve this level of performance, you will likely have a significant improvement to your program. The green area also indicates energy efficient (power) parallel speedups.
