内存与变量打印

打印GlobalTensor

GlobalTensor一般用来存放Global Memory（外部存储）的全局数据。

输入以下命令，进行GlobalTensor变量打印。以cGlobal为例，zGm所在内存地址请参考address_ 字段，此处为“0x000012c045400000”。

(msdebug) p cGlobal
(AscendC::GlobalTensor<float>) $0 = {
  AscendC::BaseGlobalTensor<float> = {
    address_ = 0x000012c045400000
    oriAddress_ = 0x000012c045400000
  }
  bufferSize_ = 655360
  shapeInfo_ = {
    shapeDim = '\0'
    originalShapeDim = '\0'
    shape = ([0] = 0, [1] = 0, [2] = 0, [3] = 0, [4] = 0, [5] = 0, [6] = 0, [7] = 0)
    originalShape = ([0] = 0, [1] = 0, [2] = 0, [3] = 0, [4] = 0, [5] = 0, [6] = 0, [7] = 0)
    dataFormat = ND
  }
  cacheMode_ = CACHE_MODE_NORMAL
}

因GlobalTensor类型变量实际的值保存在GM内存中，输入以下命令，打印GM内存中位于地址“0x000012c045400000”上的值，打印格式设置为：打印1行，每行256字节，按照float32格式打印。

(msdebug) x -m GM -f float32[] 0x000012c045400000 -s 256 -c 1
0x12c045400000: {4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096}

打印LocalTensor

LocalTensor一般用于存放AI Core中Local Memory（内部存储）的数据。

输入以下命令，进行LocalTensor变量打印。以reluOutLocal为例，reluOutLocal所在内存地址请参考address_字段中的bufferAddr参数，此处位于0上，长度为131072。

(msdebug) p reluOutLocal
(AscendC::LocalTensor<float>) $2 = {
  AscendC::BaseLocalTensor<float> = {
    address_ = (dataLen = 131072, bufferAddr = 0, bufferHandle = "", logicPos = '\n')
  }
  shapeInfo_ = {
    shapeDim = '\0'
    originalShapeDim = '\0'
    shape = ([0] = 0, [1] = 1092616192, [2] = 4800, [3] = 1473680, [4] = 0, [5] = 1473888, [6] = 0, [7] = 1471968)
    originalShape = ([0] = 0, [1] = 3222199212, [2] = 4800, [3] = 1, [4] = 0, [5] = 1473376, [6] = 0, [7] = 1473376)
    dataFormat = ND
  }
}

该tensor变量的实际内容保存在UB内存中，输入以下命令，打印UB内存中位于地址0上的值，打印格式设置为：打印1行，每行256字节，按照float32格式打印。

本用例中，tensor变量的实际内容保存在UB上，但LocalTensor不一定都保存在UB中，也可能在L1/L0A/L0B上，需要用户根据代码自行判断，然后在打印命令的-m选项中选择正确的内存类型。

(msdebug) x -m UB -f float32[] 0 -s 256 -c 1
0x00000000: {4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096 4096}

打印所有局部变量

输入以下命令，打印当前作用域所有局部变量。

(msdebug) var
(MatmulLeakyKernel<__fp16, __fp16, float, float> *) this = 0x0000000000167b60
(uint32_t) count = 0
(const uint32_t) roundM = 2
(const uint32_t) roundN = 5
(uint32_t) startOffset = 0
(AscendC::DataCopyParams) copyParam = (blockCount = 256, blockLen = 16, srcStride = 0, dstStride = 64)
