Web3.2.4 workgroup 分配. 通常一个opencl kernel需要用到多个workgroup, 在Adreno GPU中，一个workgroup被分配给一个SP，通常在同一时间内一个SP只能运行一个workgroup。如果还有有剩下的workgroup需要执行，会在GPU中排队等待执行。以3-2所示的2维workgroup为例，同时假设该GPU有4个SP。 Web13 de abr. de 2016 · Answer: you are absolutely right. This is the right way to handle such case. Carefully design the local work group size (considering factors such as register usage, cache hit/miss, memory access pattern and so on). And then pad your global work size to a multiple of local work size. Then, you are good to go.
