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：

    $$out = x1@x2 * scale + offset$$

  • bias int32：

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

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

    $$out = x1@x2 * scale + bias$$

  • pertoken无bias：

    $$out = x1@x2 * scale * pertokenScaleOptional$$

  • pertoken, bias int32（此场景无offset）：

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

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

    $$out = x1@x2 * scale * pertokenScaleOptional + bias$$

aclnnQuantMatmulV4GetWorkspaceSize

• 参数说明：

  • x1（aclTensor*，计算输入）：公式中的输入x1，数据类型支持INT8、INT32、INT4，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，数据格式支持ND，shape最少是2维，最多是6维，在transposeX1为false情况下各个维度表示：（batch，m，k），batch可不存在。当数据类型为INT32、INT4时，为INT4量化场景，当前仅支持Atlas A2训练系列产品/Atlas 800I A2推理产品，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，数据类型支持INT8、INT32、INT4，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，数据格式支持ND格式和昇腾亲和数据排布格式。当数据类型为INT32、INT4时，为INT4量化场景，当前仅支持Atlas A2训练系列产品/Atlas 800I A2推理产品，2维ND格式。
    • ND格式下，shape最少是2维，最多是6维，在transposeX2为false情况下各个维度表示：（batch，k，n），batch可不存在，其中k与x1的shape中的k一致。
    • 昇腾亲和数据排布格式下，shape最少是4维，最多是8维。在transposeX2为true情况下各个维度表示：（batch，k1，n1, n0, k0），batch可不存在，其中k0 = 32, n0 = 16, x1 shape中的k和x2 shape中的k1需要满足以下关系：ceilDiv(k,32) = k1。在transposeX2为false情况下各个维度表示：（batch，n1，k1, k0, n0）,batch可不存在，其中k0 = 16, n0 = 32, x1 shape中的k和x2 shape中的k1需要满足以下关系：ceilDiv(k,16) = k1。 可使用aclnnCalculateMatmulWeightSizeV2接口以及aclnnTransMatmulWeight接口完成输入Format从ND到昇腾亲和数据排布格式的转换。（当输入x2为昇腾亲和数据排布格式时，当前Atlas 推理系列产品上QuantBatchMatmulV3算子不支持transposeX2为false的场景）
    • 数据类型为INT4时，在transposeX2为true情况下各个维度表示：（n, k），要求k为偶数；在transposeX2为false情况下各个维度表示：（k, n），要求n为偶数。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。
  • scale（aclTensor*，计算输入）：公式中的输入scale，量化参数，数据类型支持UINT64，INT64，FLOAT32，BFLOAT16，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。
    • 输出为INT8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。
    • 输出为BFLOAT16时，直接将BFLOAT16或FLOAT32类型的scale传入本接口。
    • 输出为FLOAT16时，如果pertokenScaleOptional不为空，可直接将FLOAT32类型的scale传入本接口；如果pertokenScaleOptional为空，则需提前调用TransQuantParamV2算子的aclnn接口来将scale转成INT64、UINT64数据类型，其中BFLOAT16仅Atlas A2训练系列产品/Atlas 800I A2推理产品 支持。
  • offset（aclTensor*，计算输入）：公式中的输入offset，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。
  • pertokenScaleOptional（aclTensor*，计算输入）：公式中的输入pertokenScaleOptional，可选的量化参数，数据类型支持FLOAT32，数据格式支持ND，shape是1维（t，），t = m，其中m与x1的m一致。（Atlas 推理系列产品不支持pertokenScaleOptional）
  • bias（aclTensor*，计算输入）：公式中的输入bias，可选参数。数据类型支持INT32，BFLOAT16，FLOAT16，FLOAT32，数据格式支持ND，shape支持1维（n，）或3维（batch，1，n），n与x2的n一致。当out的shape为2、4、5、6维或x1和x2为int32/int4时，bias的shape只支持1维(n,)。
  • transposeX1（bool，计算输入）：表示x1的输入shape是否包含transpose，默认是false，若为true，x1的shape表示为（batch，k，m），batch可不存在。x1和x2为int32/int4时，transposeX1仅支持false。
  • transposeX2（bool，计算输入）：表示x2的输入shape是否包含transpose，默认是false，若为true，x2的shape表示为（batch，n，k），batch可不存在。
  • out（aclTensor*， 计算输出）：公式中的输出out，数据类型支持FLOAT16，INT8，BFLOAT16，支持非连续的Tensor，数据格式支持ND，shape最少是2维，最多是6维，（batch，m，n），batch可不存在，支持x1与x2的batch维度broadcast，输出batch与broadcast之后的batch一致，m与x1的m一致，n与x2的n一致。其中BFLOAT16仅Atlas A2训练系列产品/Atlas 800I A2推理产品支持。
  • workspaceSize(uint64_t*，出参)：返回需要在Device侧申请的workspace大小。
  • executor(aclOpExecutor**，出参)：返回op执行器，包含了算子计算流程。

• 返回值：

  aclnnStatus：返回状态码，具体参见aclnn返回码。

  第一段接口完成入参校验，出现以下场景时报错：
  - 161001(ACLNN_ERR_PARAM_NULLPTR)：
  1. 传入的x1、x2、scale或out是空指针。
  - 161002(ACLNN_ERR_PARAM_INVALID)：
  1. x1、x2、bias、scale、offset或out的数据类型和数据格式不在支持的范围之内。
  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。

aclnnQuantMatmulV4

• 参数说明：

  • workspace(void*, 入参)：在Device侧申请的workspace内存地址。
  • workspaceSize(uint64_t, 入参)：在Device侧申请的workspace大小，由第一段接口aclnnQuantMatmulV4GetWorkspaceSize获取。
  • executor(aclOpExecutor*, 入参)：op执行器，包含了算子计算流程。
  • stream(aclrtStream, 入参)：指定执行任务的AscendCL Stream流。

• 返回值：

  aclnnStatus：返回状态码，具体参见aclnn返回码。
