DefaultKernelPolicy

功能说明

默认的kernel层静态policy。

所属头文件链接

/include/elewise/kernel/builder.h

数据结构

struct DefaultKernelPolicy {
    DefaultSegmentPolicy segmentPolicy;
};

数据结构成员说明

成员名称	成员类型	成员说明	默认值
segmentPolicy	DefaultSegmentPolicy	枚举，代表tiling切分的方式，目前只支持UniformSegment，代表均匀切分	UniformSegment

约束说明

NA

使用示例

template <typename InputDtype, typename OutputDtype>
struct AddSubConfig {
    struct AddSubCompute {
        template <template <typename> class Tensor>
