Abstract

The invention provides a tensor calculation code optimization method and device, electronic equipment and a medium. The method comprises the steps that loop characteristics and calculation graph characteristics of tensor calculation codes are analyzed, corresponding loop information and calculation graph information are obtained, an optimization space is generated according to the loop information, the calculation graph information and a preset optimization method, and each space point in the optimization space represents a preset optimization method combination and parameter selection. Basedon a simulated annealing algorithm and a reinforcement learning algorithm, a target space point is searched and determined in the optimization space; and according to a preset optimization method combination and parameter selection corresponding to the target space point, optimized a tensor calculation code so that automatic optimization of the tensor calculation code can be quickly completed, theoperation efficiency of the tensor calculation code is improved, for programming developers, the human input of a development operator can be avoided, relatively good performance can be obtained, cost can be reduced, and the development efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of code optimization, in particular to a tensor calculation code optimization method and device, an electronic device, and a computer-readable medium. Background technique [0002] Code optimization refers to the process of transforming the program code without changing the running results of the program to improve the running efficiency of the program. Code optimization can be performed at various stages of program compilation. [0003] A tensor is a multidimensional array that is classified hierarchically based on the order of the array elements. For example, you can think of a scalar as a zero-order tensor, a vector as a first-order tensor, a matrix as a second-order tensor, and a data volume as a three-dimensional tensor. rank tensor, and so on. [0004] Tensor computing has important applications in artificial intelligence, scientific computing, image processing and other fields. When optim...
