WebFeb 21, 2016 · In conditionally executed code, a bar instruction should only be used if it is known that all threads evaluate the condition identically (the warp does not diverge). Since barriers are executed on a per-warp basis, the optional thread count must be a multiple of the warp size. I am still a bit confused about the mechanism explained in this quote.
