Abstract


High-performance computing technology has always been the commanding heights of the entire information technology to promote the development of information technology . Current high performance computer system constituted by a large number of processing node processing node via the interconnection between the networks to communicate and collaborate . With parallel processing have been expanding , people have been in the pursuit of simple structure, the degree of nodes , the network diameter is small and scalable parallel computer interconnection network topology , in order to further improve the communication efficiency of the parallel computer . For the interconnection network topology has done a lot of research and a variety of interconnection network topology , but most network topology node connectivity , network diameter , and scalability of these three areas are often trade-off , can not meet the requirements of the people . First , the article describes three very generic simple interconnection network topology , they are ring , Petersen graph and hypercube networks are analyzed and compared , and the structure and characteristics of these three interconnected network , which proposed a new types of interconnection network topology PGLH for ( Petersen graph looped hypercube ) , the network structure having a ring network at the same time simple scalability , the Petersen FIG short diameter and a hypercube network connectivity , more flexible in use . Secondly, the problems for the existing multicast algorithm on the hypercube networks , clustering multicast algorithm and its application on the PGLH interconnection network topology in-depth study . First, the layered structure characterized in for PGLH network , a a layered multicast model ; Secondly, for the the hypercube network multicast communication multicast destination node locality characterized in low utilization rate , and the multicast algorithm serial issue, a PGLH interconnection network based on the hierarchical distributed multicast algorithm . Finally, as to the application of the results of these studies , the latest Java programming language under the Eclipse platform simulation experiment . According to different multicast algorithm in the same node capacity interconnection network topology , a large number of test experiments , summed layered multicast algorithm capabilities and analysis of the various aspects of the problems , provide direction for further research and valuable experience .
