Event supports cross-process and cross-device (IPC event) Co-authored-by: liujunzhu<liujunzhu@huawei.com> # message auto-generated for no-merge-commit merge: !28123 merge master into master Event supports cross-process and cross-device (IPC event) Created-by: liujunzhu Commit-by: liujunzhu Merged-by: ascend-robot Description: <!-- Thanks for sending a pull request! --> **What type of PR is this?** > Uncomment only one /kind <> line, hit enter to put that in a new line, and remove leading whitespaces from that line: > > /kind bug > /kind task /kind feature **What does this PR do / why do we need it**: event能力对齐cuda，支持跨进程与跨设备使用。 CUDA跨进程共享内存和跨设备拷贝内存时使用Event进行同步，而torch npu使用SynchronizeStream进行同步，希望torch_npu支持在跨设备和跨内存的场景也使用Event进行同步，提升整体性能。另外，需支持通过Python接口在进程间传递Event对象或Event handle并使用该Event进行进程间的同步。 相关场景如下： 1、跨进程使用Event：进程间传递interprocess=True的Event对象、Event的IPC Handle或torch.multiprocessing.reductions.reduce_event(event)的结果。 2、跨进程共享NPU内存：包括进程间通过参数或队列传递Tensor、进程间通过torch.multiprocessing.reductions.reduce_tensor()传递Tensor、进程间通过_share_npu_传递Tensor。 3、跨设备拷贝NPU内存：调用Tensor.to()或Tensor.copy_()接口。 不支持跨设备或跨进程使用interprocess=False的Event。 **Which issue(s) this PR fixes**: <!-- *Automatically closes linked issue when PR is merged.
