Shows concrete PyTorch changes for Ascend NPU: adds privateuse1 plugin loading in PyTorch 2.1 so backends auto-import via Python entry points, provides an OpenRidge CPU-sim backend for compatibility tests (more than 10 capability issues found in two months), implements an MPU graph to cut inference latency from >100 ms to 28 ms, inductor+Triton backend in PyTorch 2.6, and operator/runtime tweaks that claim up to 50% CPU overhead reduction and production-grade training and inference on Ascend.
