> Warps of threads within a thread block are not guaranteed to run in any order, and there are no guarantees that, e.g., if warp A spins on a lock hold by warp B, that warp B will ever run and make process, and therefore the thread block might never run to completion. FYI this is wrong, pre-Volta guarantees that all warps will run to completion, what it doesn't guarantee is the same for threads within a warp. post-Volta guarantees that. |
