Abstract

The invention discloses an error-controllable hybrid precision operator automatic optimization method, which comprises the following steps of: first optimization: under given input, optimizing a general matrix multiplication function through an ID (Identity) conversion method, and recording an operation sequence and a corresponding dimension of the general matrix multiplication function; second optimization: according to an optimized general matrix multiplication GEMM function ID list and a general matrix multiplication function sequence list, transmitting the input of each non-optimized general matrix multiplication calling function to a preset fast matrix multiplication function of different parameter combinations, and carrying out performance timing and error calculation; and third optimization: analyzing the obtained data, converting a single-precision matrix multiplication algorithm into a mixed-precision matrix multiplication operator, and outputting an optimized code. By using the method, the hybrid precision GEMM operator can help to improve the performance in a more complex and wider high-performance computing program. The method can be widely applied to the field of compilers.
