Opencl workgroup
Did you know?
WebIt's basically a kind of abstraction of the hardware. While subgroups act in lockstep, the whole threadgroup shared local memory cache. Multiple threadgroups can run on a single compute unit, which has a single bank of cache. Choosing a threadgroup size is primarily a task of optimizing usage of a compute unit. 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.
