Cleanup CUB block/thread load and exchange #1946

bernhardmgruber · 2024-07-05T21:29:04Z

Since I had to read into CUB's block/thread load and block exchange, here are a few improvements.

Let's also check for any SASS differences, since this code is at the heart of all CUB algorithms:

Check if SASS of cub.test.block_load.it_11 changed. - Identical before and after this PR.

cub/cub/block/block_load.cuh

  template <int DUMMY>
  struct LoadInternal<BLOCK_LOAD_DIRECT, DUMMY>
  {
-    /// Shared memory storage layout type
    using TempStorage = NullType;


Starting from here, I deleted all the documentation blocks of the LoadInternal specializations, because they are private inside of BlockLoad and named Internal. Furthermore, their behavior is amply documented in the BlockLoadAlgorithm enumeration. Also, the comments were highly redundant and were at least one time wrong.
