WebJun 10, 2024 · In this case, a wave of 80 thread blocks fully occupies the GPU. Suppose a task creates 96 thread blocks. The first 80 will be computed efficiently as a ‘full wave’ while the 16 leftover thread blocks will make up an inefficient ‘tail wave’ during which the GPU is underutilized. Figure 5 illustrates a simple version of this situation ...
