Moore's law will grant computer architects ever more transistors for the foreseeable future, and the challenge is how to use them to deliver efficient performance and flexible programmability. We proposed a many-core architecture, Godson-T, to attack this challenge. On the one hand, Godson-T features a region-based cache coherence protocol, asynchronous data transfer agents and hardware-supported synchronization mechanisms, to provide full potential for high efficiency of the on-chip resource utilization. On the other hand, Godson-T features a high efficient runtime system, a Pthreads-like programming model, and versatile parallel libraries, which make this many-core design flexibly programmable. This hardware/software cooperating design methodology bridges the high-end computing with mass programmers. Experimental evaluations are conducted on a cycle-accurate simulator and sample chip of Godson-T. The results show that the proposed architecture has good scalability, fast synchronization, high computational efficiency, and flexible programmability.


Dongrui Fan received Ph.D. degree of computer architecture in 2005 from Institute of Computing Technology, Chinese Academy of Sciences, and now he is an associate professor. Dongrui participated Godson-1 and Godson-2 micro-architecture designs from 2000. Currently, his research interests focus on multi-core/many-core architecture and low-power embedded micro-architecture design. He leads AMS research group and designed the new processor models -- Godson-X and Godson-T, which are research models for the new generation Godson series chips. Dongrui is Technical Committee Member of Computer Architecture and System Software of China Computer Federation (CCF) and HiPEAC/IEEE/ACM member. He serves as a Program Committee Member of the International Conference on Parallel and Distributed Computing, Applications and Technologies (PDCAT) in 2009 and 2010. He also serves as the Program Vice-Chair of Multi-Core and Parallel Systems in the 40th International Conference on Parallel Processing (ICPP) in 2011, and serves for several workshops. Dongrui leads or participates many Chinese national science projects, EU FP7 project, Sino-Swiss project, Sino-US project. He published papers on MICRO, IPDPS, CGO, CF, EuroPar, Trans. on HiPEAC, etc.
