Can you explain? How much does it actually affect results in extreme cases? The source of non-determinism does seem the GPU but parallelism and dynamic allocation in the frameworks. (Also seems that some parts of pytorch still return runtime error if you request a deterministic version). Are there other more performant deterministic DL frameworks?
