aclnnQuantMatmulV4

支持的产品型号

  • Atlas A2 训练系列产品/Atlas 800I A2 推理产品
  • Atlas 推理系列产品

接口原型

每个算子分为两段式接口，必须先调用“aclnnQuantMatmulV4GetWorkspaceSize”接口获取计算所需workspace大小以及包含了算子计算流程的执行器，再调用“aclnnQuantMatmulV4”接口执行计算。

  • aclnnStatus aclnnQuantMatmulV4GetWorkspaceSize(const aclTensor *x1, const aclTensor *x2, const aclTensor *scale, const aclTensor *offset, const aclTensor *pertokenScaleOptional, const aclTensor *bias, bool transposeX1, bool transposeX2, const aclTensor *out, uint64_t *workspaceSize, aclOpExecutor **executor)

  • aclnnStatus aclnnQuantMatmulV4(void *workspace, uint64_t workspaceSize, aclOpExecutor *executor, aclrtStream stream)

功能描述

  • 算子功能：兼容aclnnQuantMatmulV3接口功能，在其基础上新增pertoken特性。完成量化的矩阵乘计算，最小支持输入维度为2维，最大支持输入维度为6维。相似接口有aclnnMm（仅支持2维Tensor作为输入的矩阵乘）和aclnnBatchMatMul（仅支持三维的矩阵乘，其中第一维是Batch维度）。
  • 计算公式：

    • 无pertoken无bias：

      out=x1@x2∗scale+offsetout = x1@x2 * scale + offset

    • bias int32：

      out=(x1@x2+bias)∗scale+offsetout = (x1@x2 + bias) * scale + offset

    • bias bfloat16/float32（此场景无offset）：

      out=x1@x2∗scale+biasout = x1@x2 * scale + bias

    • pertoken无bias：

      out=x1@x2∗scale∗pertokenScaleOptionalout = x1@x2 * scale * pertokenScaleOptional

    • pertoken， bias int32（此场景无offset）：

      out=(x1@x2+bias)∗scale∗pertokenScaleOptionalout = (x1@x2 + bias) * scale * pertokenScaleOptional

    • pertoken， bias bfloat16/float16/float32（此场景无offset）：

      out=x1@x2∗scale∗pertokenScaleOptional+biasout = x1@x2 * scale * pertokenScaleOptional + bias

aclnnQuantMatmulV4GetWorkspaceSize

  • 参数说明：

    • x1（aclTensor*，计算输入）：公式中的输入x1，device侧的aclTensor。数据格式支持ND。支持最后两根轴转置情况下的非连续tensor，其他场景的非连续的Tensor不支持，shape支持2~6维，在transposeX1为false情况下各个维度表示：（batch，m，k），在transposeX1为true情况下各个维度表示：（batch，k，m），batch可不存在。
      • Atlas 推理系列产品：数据类型支持INT8。
      • Atlas A2 训练系列产品/Atlas 800I A2 推理产品：数据类型支持INT8、INT32、INT4。当数据类型为INT32、INT4时，为INT4量化场景，当前仅支持2-6维ND格式，transposeX1为false情况。其中当x1数据类型为INT4时，维度表示：（batch，m，k），要求k为偶数，当x1数据类型为INT32时，每个INT32数据存放8个INT4数据，对应维度表示：（batch，m，k // 8），要求k为8的倍数。
    • x2（aclTensor*，计算输入）：公式中的输入x2，device侧的aclTensor。数据格式支持ND格式和昇腾亲和数据排布格式。支持最后两根轴转置情况下的非连续tensor，其他场景的非连续的Tensor不支持。
      • ND格式下，shape支持2~6维，在transposeX2为false情况下各个维度表示：（batch，k，n），在transposeX2为true情况下各个维度表示：（batch，n，k），batch可不存在，其中k与x1的shape中的k一致。

        • 数据类型为INT32时，每个INT32数据存放8个INT4数据，在transposeX2为true情况下各个维度表示：（n，k // 8），要求k为8的倍数；在transposeX2为false情况下各个维度表示：（k，n // 8），要求n为8的倍数。
        • 可使用aclnnConvertWeightToINT4Pack接口完成x2从INT32（1个int32在0~3bit位存储1个int4）到INT32（1个int32存储8个int4）或INT4（1个int4表示1个int4）的数据格式转换，具体参见aclnnConvertWeightToINT4Pack接口。

      • Atlas A2 训练系列产品/Atlas 800I A2 推理产品：数据类型支持UINT64、INT64、FLOAT32、BFLOAT16。
      • 当原始输入类型不满足约束与限制中的数据类型组合时，需要提前调用TransQuantParamV2算子的aclnn接口来将scale转成INT64、UINT64数据类型。
    • offset（aclTensor*，计算输入）：公式中的输入offset，device侧的aclTensor。可选量化参数，数据类型支持FLOAT32，数据格式支持ND，shape是1维（t，），t = 1或n，其中n与x2的n一致。

2. x1、x2、bias、scale、offset或out的shape不满足校验条件。
3. x1、x2、bias、scale、offset或out是空tensor。
4. x1与x2的最后一维大小超过65535，x1的最后一维指transposeX1为true时的m或transposeX1为false时的k，x2的最后一维指transposeX2为true时的k或transposeX2为false时的n。
