DeepXTrace supports diagnosis of various slowdown scenarios, including:

* *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).
* *Comp-Slow*: Slowdown caused by sender-side issues, such as uneven computation (e.g., Attention/MoE) that delays `send` communication operators.
* *Mixed-Slow*: Slowdown caused by receiver-side issues, such as uneven computation (e.g., Attention/MoE) that triggers early `recv` communication operators on GPUs, or hotspot experts that cause network Incast.
* *Comm-Slow*: Slowdown caused by the communication path between the sender and receiver (e.g., communication link issues).
