一种新型的Free-memory众核处理器片上通信接口
A Novel Free-memory Communication Interface of Many CoresProcessor
摘要
Abstract
High-performance computing has witnessed a tremendous growth and acceptance over the last decade,primarily due to the availability of clusters. The performance of these clusters hinges upon the communication interface. User level communication based on storing address translation table in off-chip SRAM has deeply increased the design complex and cost of chip and system. The paper put forward and implemented a novel Fnee-Memory communication interface of many cores processor which differs from traditional HCA based on 1/O bus, without local memory inteface and reduced cost of address translation by effcient cache management, method.Experimental results show the communication interface which we implemented not only can reduces the design complex and cost of chip and system, but also can achieve better bandwidth and latency than infiniband QDR HCA.关键词
