Pull request overview
This PR updates the hw_queue_eval run CLI command to enable PyTorch profiling in a way that matches the harness’s multi-GPU stream distribution, avoiding single-GPU-only profiling behavior when multiple GPUs are available.
Changes:
- Add a dedicated profiling phase that creates multi-GPU streams (round-robin across available GPUs) to mirror the harness behavior.
- Synchronize all involved CUDA devices after each profiled iteration to ensure multi-GPU work is fully captured.
- Add CLI output describing whether profiling is using single- or multi-GPU mode and the stream-to-device distribution.
