WebYour global work size is executed in chunks of local work size (in theory), if you set 1 as your local work group size, then it would execute only 1 thread in each local work group. On GPUs, work groups match to compute units - if you have a work group size of 1, your 1 thread may potentially occupy a whole compute unit. Web22 apr. 2024 · This is known as the local size of the work group. Every compute shader has a three-dimensional local size (again, sizes can be 1 to allow 2D or 1D local …
