Abstract

The invention relates to a deep learning framework transplanting and optimizing method and system based on a target many-core. The method comprises the steps: in a transplanting process, transplantinga source code of a deep learning framework to a target many-core machine, modifying and compiling the framework according to a compiling instruction of the target many-core machine, and enabling theframework to meet the operation conditions of the target many-core machine; the acceleration optimization process comprises the steps that the framework is used for operating a functional model basedon deep learning on domestic many-cores, a target many-core performance analysis tool is used for analyzing codes, and confirmation and extraction of hotspot functions are achieved; analyzing and testing features and function parameters of the hotspot function; accelerating the hotspot function by using a parallel acceleration library; and determining an optimization strategy, finally improving the speed-up ratio of the framework on the premise of ensuring the correctness of the framework, and modifying and testing the compiled file of the deep learning framework according to the current master-slave core parallel code so as to realize the hybrid compilation and operation of the current master-slave core parallel code.

Description

Technical field [0001] The present invention relates to the technical field of high-performance computing, and more specifically, to a method and system for transplanting and optimizing a deep learning framework based on target many cores. Background technique [0002] With the rapid development of artificial intelligence, deep learning, as a powerful technical support of artificial intelligence, has been widely used in handwritten number recognition, speech recognition, and image understanding. With the rapid development of data and hardware equipment, convolutional neural networks have also gone from the initial 5 layers and 6 layers to the 152-layer ResidualNet proposed by MSRA, and even deeper layers. And as humans have higher and higher requirements for information processing capabilities, ordinary single-core or multi-core processors can no longer meet the demand for massive calculations in deep learning. [0003] At present, neural networks are all relying on graphics calcu...
