| ## How can this functionality help? | ||
| Increase throughput of your model. | ||

| Imagine your for loop needs to iterate on the data for `n` times, and it takes time `t` to process 1 sample (yielding a throughput of `1/t`). If we were to unroll the for loop onto `n` devices, then we can push `n` microbatches into the pipeline, each microbatch containing 1 sample. Then at any timeslot, the pipeline is processing `n` samples, yielding a throughput of `n/t`. |

does this only work if the batch size can be split into n microbatches?
