چکیده

In this paper, we propose and evaluate a bidi-rectional slotted ring architecture for the distributed shared memory multiprocessor model. The performance of the bidirectional ring is compared against the unidirectional ring model using analytical models. The eeects of workload parameters such as miss rate, communication locality and system size on processor utilization and eeective computation power are analyzed. Our study shows that bidirectional slotted rings provide about 15 to 35% better processor utilization than unidirectional rings with the same link width.

A Cache Coherence Protocol for the Bidirectional Ring Based Multiprocessor

In this paper, a new cache protocol for ring based shared memory multiprocessors is discussed and analyzed. The proposed protocol uses multicasting of rings to reduce the message traversal length. The simulation results show that the proposed protocol with a bidirectional ring improved the system performance by 8% to 30% as compared to Barroso’s protocol using a unidirectional ring. Assuming th...

Length and Processor Speed on the Performance ofthe

This paper presents a comparative study of the performance of the bidirectional ring and the unidirec-tional ring multiprocessor, with emphasis on the eeect of system parameters, speciically, the message length and the relative processor speed. The choice of these parameters may not be optimum due to the performance cost tradeoos in practice. Our study shows that the use of bidirectional ring i...

Performance Analysis of a New Neural Network for Routing in Mesh Interconnection Networks

Routing is one of the basic parts of a message passing multiprocessor system. The routing procedure has a great impact on the efficiency of a system. Neural algorithms that are currently in use for computer networks require a large number of neurons. If a specific topology of a multiprocessor network is considered, the number of neurons can be reduced. In this paper a new recurrent neural ne...
