Description
**Is your feature request related to a problem? Please describe.**
vLLM supports symmetric memory enablement API from [v0.11.0](https://docs.vllm.ai/en/latest/api/vllm/distributed/device_communicators/pynccl_allocator.html#vllm.distributed.device_communicators.pynccl_allocator.nccl_symm_mem_context).
With NCCL v2.29 (next release), symmetric memory enablement will become beneficial IB domain communication as well.
