- PyTorch: 37 events in the last 90 days
- PyTorch: 37th Release in the last 90 days

What happened
Several tests rely on legacy ProcessGroupNCCL-specific APIs, deferred collective communicator creation, or multiple devices per process. Select nccl-legacy explicitly for those compatibility tests so switching the nccl alias to NCCL2 does not change what they are intended to exercise.
