 # DeepXTrace
 
-DeepXTrace is a lightweight system tool designed to efficiently and precisely locate slow ranks in DeepEP-based environments by enhancing the [DeepEP](https://github.com/deepseek-ai/DeepEP) communication library. It is composed of two core components: *DeepEP Metrics Probe* and *DeepXTrace Metrics Analysis*.
+DeepXTrace is a lightweight diagnostic tool designed to efficiently and precisely locate slow ranks in MoE-based distributed environments through instrumentation of communication libraries (e.g., [DeepEP for GPU](https://github.com/deepseek-ai/DeepEP), [MC2 for NPU](https://gitcode.com/cann/ops-transformer)). It is composed of two core components: *MoE COMM Metrics Probe* and *DeepXTrace Metrics Analysis*.
 
 DeepXTrace supports diagnosis of various slowdown scenarios, including:
 
-* *Comp-Slow*: Slowdown caused by the destination rank(e.g., GPU/CPU compute latency).
+* *Comp-Slow*: Slowdown caused by the destination rank (e.g., xPU compute latency).
 * *Mixed-Slow*: Slowdown caused by the source rank(e.g., uneven expert distribution or hotspot congestion).
 * *Comm-Slow*: Slowdown caused by the communication path between specific source and destination ranks(e.g., communication link issues).
