During roofline analysis, what does it indicate about a kernel if its position on the graph falls strictly below the horizontal 'peak compute' line but to the left of the 'ridge point'?

When a kernel falls to the left of the ridge point and below the peak compute line on a roofline graph, it is classified as memory-bound. The ridge point is the specific threshold on a roofline graph where a kernel transitions from being limited by how fast it can move data to being limited by how fast it can perform calculations; it represents the ratio of arithmetic operations to data movement that matches the ....
