FPGA engineering test method of federated learning system

Abstract

The embodiment of the invention provides an FPGA engineering test method. An FPGA is applied to a heterogeneous processing system for federated learning, the heterogeneous processing system comprisesan upper computer and the FPGA, the test method comprises the steps that the upper computer sends configuration data and test source data to the FPGA, and the configuration data comprises specified test configuration data; and the FPGA receives the test source data and processes the test source data in a specified test module according to the configuration data to obtain test result data. Throughthe FPGA engineering test mode, the specified test module of the FPGA can be tested, and once an abnormality occurs, the abnormality of the specified test module of the FPGA can be directly positioned, so that the troubleshooting range is narrowed and the FPGA engineering test efficiency is improved in comparison with direct engineering test on the whole module.

Description

technical field [0001] The embodiments of this specification generally relate to the field of federated learning, and in particular, relate to an FPGA engineering testing method used in a federated learning system. Background technique [0002] Federated learning is a system based on distributed learning, which disperses the calculation of machine learning to the databases of participating parties for encrypted distributed computing. In order to coordinate each distributed computing node, the gradient-related data needs to be transmitted, which requires privacy protection for the gradient-related data, and the complexity of the related algorithm is relatively high. The federated learning system has a huge demand for computing performance, and field programmable gate array FPGA (Field Programmable Gate Array) provides powerful computing performance for federated learning.
