- Flop/s Rate: This represents the variety of floating-point operations per 2nd achieved by the system. It is a necessary metric for understanding computational efficiency.
- Memory Bandwidth: The optimum information transfer rate in between RAM and the processor, frequently a restricting element in overall system performance.
The Roofline Graph
The Roofline design is usually visualized using a graph, where the X-axis represents operational strength (FLOP/s per byte), and the Y-axis shows performance in FLOP/s.
| Operational Intensity (FLOP/Byte) | Performance (FLOP/s) |
|---|---|
| 0.01 | 100 |
| 0.1 | 2000 |
| 1 | 20000 |
| 10 | 200000 |
| 100 | 1000000 |
In the above table, as the functional intensity boosts, the possible performance also rises, demonstrating the importance of optimizing algorithms for greater functional effectiveness.
