核切换

参考以下操作可将当前聚焦的核切换至指定的核。

• 如果当前运行的核为aiv的“core 1”，指定切换的核为aiv的“core 2”。

  (msdebug) ascend aiv 2
  [Switching to focus on Kernel add_custom, CoreId 2, Type aiv]
  * thread #1, name = 'add_custom_npu', stop reason = breakpoint 1.1
      frame #0: 0x000000000000380c device_debugdata`::add_custom(uint8_t *__restrict, uint8_t *__restrict, uint8_t *__restrict) [inlined] KernelAdd::CopyOut(this=0x000000000016e9b8, progress=0) at add_custom.cpp:85:9
     82  	        // copy progress_th tile from local tensor to global tensor
     83  	        DataCopy(zGm[progress * TILE_LENGTH], zLocal, TILE_LENGTH);
     84  	        // free output tensor for reuse
  -> 85  	        outQueueZ.FreeTensor(zLocal);
     86  	    }
     87  	
     88  	private:

  完成切换后，再次查询核信息可看到已切换至新指定的核id所在行。

  (msdebug) ascend info cores
    CoreId  Type  Device Stream Task Block         PC               Exception
      1     aiv      1     3     0     0     0x1240c001a80c         f0000000

  (msdebug)

• 如果当前运行的核为aiv的“core 5”，指定切换的核为aic的“core 4”。

  (msdebug) ascend aic 4
  [Switching to focus on Kernel _Z23matmul_leakyrelu_customPhS_S_S_S_S_S_, CoreId 4, Type aic]

     56               rpcCommSrv[i].eventIDMmProcesss = eventIDMmProcesss;
     57           }
     58           SetFlag<HardEvent::MTE3_MTE2>((event_t)eventIDMmCnt);
  -> 59           SetFlag<HardEvent::MTE3_MTE2>((event_t)eventIDMmProcesss);
     60       }
     61
