数据结构

enum class ParamUsage {
    IN,
    OUT,
    IN_OUT,
}

数据结构成员说明

成员名称	成员类型	成员说明	默认值
IN	NA	输入	NA
OUT	NA	输出	NA
IN_OUT	NA	输入&输出	NA

约束说明

NA

使用示例

template <typename InputDtype, typename OutputDtype>
struct AddSubConfig {
    struct AddSubCompute {
        template <template <typename> class Tensor>
        __host_aicore__ constexpr auto Compute() const
        {
            // 🔥🔥🔥 使用示例 🔥🔥🔥
            auto in1 = Atvoss::PlaceHolder<1, Tensor<InputDtype>, Atvoss::ParamUsage::IN>();
            auto in2 = Atvoss::PlaceHolder<2, Tensor<InputDtype>, Atvoss::ParamUsage::IN>();
            auto in3 = Atvoss::PlaceHolder<3, InputDtype, Atvoss::ParamUsage::IN>();
            auto out = Atvoss::PlaceHolder<4, Tensor<OutputDtype>, Atvoss::ParamUsage::OUT>();
            // 🔥🔥🔥 使用示例 🔥🔥🔥

            return (out = in1 + in2 - in3);
        };
    };

    auto arguments = Atvoss::ArgumentsBuilder{}.inputOutput(in1, in2, in3, out).attr("dim", 5).build();

    using DeviceOp = typename AddSubConfig<InputDtype, OutputDtype>::DeviceOp;
    DeviceOp deviceOp;
    deviceOp.Run(arguments, stream);
