Max work group size

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.
