Hardware feature-based operator scheduling scheme automatic search method and system

The invention provides an operator scheduling scheme automatic searching method and system based on hardware features. The method comprises the following steps: obtaining dimension information of operator input data, hardware characteristics of target hardware and capacity and hardware instruction support conditions containing each storage level; according to the storage hierarchy of the target hardware from high to low, recursively searching an acceptable optimal feasible data handling scheme of the hierarchy based on a greedy strategy on each hierarchy; wherein the data handling schemes of each level jointly form a scheduling scheme of an operator; and finally performing performance evaluation. Based on the searched operator scheduling schemes, a plurality of operators on target hardware are generated through the CodeGen technology for implementation, and then the operator scheduling scheme with the optimal performance is tested and selected on the hardware. Therefore, the technical scheme of the invention
