Abstract
Multi GPU systems achieve performance improvement through scaling out to meet the ever-in-creasing computation demand brought about by increasingly complex algorithms and the continuously increasing data in artificial intelligence.The interconnection bandwidth between processors,as well as topologies of sys-tems are the key factors that determine the performance of multi-GPU systems.In traditional PCIe-based multi-GPU systems,the PCIe bandwidth is the bottleneck that limits system performance.GPU-oriented high speed interconnection technologies become an effective method to solve the bandwidth limitation problem of multi-GPU systems at present.This article first introduces the PCIe interconnection technology and the typical topologies used in traditional multi-GPU systems.Then taking Nvidia NVLink,AMD Infinity Fabric Link,Intel Xe Link,and Biren Technology BLink as examples,GPU-oriented high speed interconnection technologies and topologies of representative GPU vendors at home and abroad are reviewed and analyzed.Finally,the research implication of interconnection technologies is discussed.关键词
