Chrome Tracing flow event demo

1.效果

2.解释

• cpu_op 为host上的op
• kernel 为device上的kernel
• 标记一条线

  {"ph": "s", "id": 13, "pid": 1, "tid": 100, "ts": 0,"cat": "ac2g", "name": "ac2g"},{"ph": "f", "id": 13, "pid": 10,   "tid": 7,   "ts": 20,"cat": "ac2g", "name": "ac2g", "bp": "e"},

• “id”: 13 每条线递增
• “ph”: “s”, “pid”: 1, “tid”: 100, “ts”: 0 从这个位置开始
• “ph”: “f”, “pid”: 10, “tid”: 7, “ts”: 20 到这个位置结束

3.代码
