aclnnLogicalAnd&aclnnInplaceLogicalAnd

支持的产品型号

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

接口原型

  • aclnnLog2和aclnnInplaceLog2实现相同的功能,使用区别如下,请根据自身实际场景选择合适的算子。

    • aclnnLog2:需新建一个输出张量对象存储计算结果。
    • aclnnInplaceLog2:无需新建输出张量对象,直接在输入张量的内存中存储计算结果。
  • 每个算子分为两段式接口,必须先调用“aclnnLogicalAndGetWorkspaceSize”或者“aclnnInplaceLogicalAndGetWorkspaceSize”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“aclnnLogicalAnd”或者“aclnnInplaceLogicalAnd”接口执行计算。

    • aclnnStatus aclnnLogicalAndGetWorkspaceSize(const aclTensor *self, const aclTensor *other, aclTensor *out, uint64_t *workspaceSize, aclOpExecutor **executor)
    • aclnnStatus aclnnLogicalAnd(void *workspace, uint64_t workspaceSize, aclOpExecutor *executor, aclrtStream stream)
    • aclnnStatus aclnnInplaceLogicalAndGetWorkspaceSize(aclTensor *selfRef, const aclTensor *other, uint64_t *workspaceSize, aclOpExecutor **executor)
    • aclnnStatus aclnnInplaceLogicalAnd(void *workspace, uint64_t workspaceSize, aclOpExecutor *executor, aclrtStream stream)
