Which property of a workload makes it a good match for accelerated execution?

選択肢

1. The workload spends most of its time waiting for user input, so adding cores shortens the part of the run that dominates it and the wait is absorbed.
2. The same operation is applied independently to a very large number of elements, so thousands of cores can work at once.
3. The dataset is small enough to fit in the processor's cache, so the transfer to device memory is cheap enough to ignore entirely.
4. Each step depends on the result of the previous step, which keeps the instruction stream simple and predictable and therefore lets the scheduler keep all of the available cores occupied without stalls.
