is there more context for: "Well, with the addition of the sparse matrix multiplication feature for Tensor Cores, my algorithm, or other sparse training algorithms, now actually provide speedups of up to 2x during training" 2x what? CPU, then it's hardly worth it. 2x per core, so #cores x 2. I'd imagine the level of sparsity is also important, but there is no mention of it.
