Hello, I was using the unitrace to trace an AI application. Below is part of my output. 

{"ph": "X", "tid": 4294950910, "pid": 4294950911, "name": "gen9_eltwise_bwd[SIMD32 {1568; 1; 1} {512; 1; 1}]", "cat": "gpu_op", "ts": 1703105438709308, "dur": 9, "args": {\
"id": "3418"}},
{"ph": "X", "tid": 4294950910, "pid": 4294950911, "name": "gen9_fused_reduce_init[SIMD32 {128; 1; 1} {1; 1; 1}]", "cat": "gpu_op", "ts": 1703105438709404, "dur": 3, "args"\
: {"id": "3419"}},

Many events with the same kernel name but different SIMD shapes. It would be good in the "name" field, it only shows the kernel name, and put the SIMD information in the "args" filed, like follows: 

{"ph": "X", "tid": 4294950910, "pid": 4294950911, "name": "gen9_eltwise_bwd", "cat": "gpu_op", "ts": 1703105438709308, "dur": 9, "args": {"id": "3418", "shape": "[SIMD32 {1568; 1; 1} {512; 1; 1}]"}},
{"ph": "X", "tid": 4294950910, "pid": 4294950911, "name": "gen9_fused_reduce_init", "cat": "gpu_op", "ts": 1703105438709404, "dur": 3, "args"\
: {"id": "3419", "shape":"[SIMD32 {128; 1; 1} {1; 1; 1}]"}},

In this way, it is easy to combine information for all the events related to the same kernel.

@zhenghh04, Thanks for raising it. I wanted to understand the visualization tool that you are using and how are you analyzing your data. We use Perfetto.ui and we found it is easy to identify issues with kernel name + SIMDs info together.
