WebNov 27, 2015 · From the CUDA C Programming Guide section F.4.2: If a non-atomic instruction executed by a warp writes to the same location in global memory for more than one of the threads of the warp, only one thread performs a write and which thread does it is undefined. See also section 4.1 of the guide for more info. WebApr 5, 2024 · So far what I have seen is that there is no need for a atomicRead in cuda because: “ A properly aligned load of a 64-bit type cannot be “torn” or partially modified by an “intervening” write. I think this whole question is silly. All memory transactions are performed with respect to the L2 cache. The L2 cache serves up 32-byte cachelines only.
