We'll need support for collaborative autotuning on multiple torchrun initiated processes.

I have event-based benchmarking infra ready in #393 (autotuner/benchmarker) which reports timing results on process 0.

We need to:

  1. Make sure all processes benchmark the same configs in the same order. (Is there any randomization in the autotuning process?)
  2. Use the event based benchmarker when in torchrun env inside autotuner. (easy)
  3. Communicate results from process 0 to all processes, OR process 0 makes a decision and communicate the optimal config to all processes. (Through caching?)
