چکیده

Interconnection network is a decisive component of parallel and distributed computer systems. With the merits of simplicity and eciency, 2-dimensional (2-D) mesh has been a popular choice of large MIMD interconnection networks. Mesh, however, has its known weaknesses in scalability and connectivity. Packed Exponential Connections (PEC) is a newly proposed network which is designed to improve the scalability and connectivity of 2-D mesh while maintaining its merits. In this study, the performance of PEC over mesh network is carefully examined through computer simulation. Characteristics of PEC networks are revealed. A novel routing scheme is proposed and used in PROTEUS environment to simulate the performance of 2-D PEC network. Simulation and analytical results show that for many applications where non-local communications are required, PEC network provides superior performance to that of mesh. Based on simulation results, structural modi®cation is also suggested to further enhance the performance of PEC network. Ó 1999 Published by Elsevier Science B.V. All rights reserved.

Comparative study of computer simulation softwares

One of the methods for analyzing systems is simulation. Network simulation is a technique that models the behavior of the network by performing transaction calculations between different network entities and using mathematical formulas and taking observations from network products. A network simulator is a piece of software or hardware that predicts the behavior of a computer network without a ...

In Search of the Biological Significance of Modular Structures in Protein Networks

Many complex networks such as computer and social networks exhibit modular structures, where links between nodes are much denser within modules than between modules. It is widely believed that cellular networks are also modular, reflecting the relative independence and coherence of different functional units in a cell. While many authors have claimed that observations from the yeast protein-pro...

Comparative Study of Nanostructured Zr-Fe2O3 and CNT Modified Zr-Fe2O3 Thin Films for Photo Electrochemical Generation of Hydrogen

Nanostructured hematite thin films are doped with zirconium successfully and also modified by introducing CNT using sol-gel method for their implementation as photo-electrode in photo-electrochemical (PEC) cell for hydrogen generation. XRD, UV-visible spectroscopy and PEC study techniques are used to characterize the thin films. The PEC responses of thin films are improved by introducing carbon...

Estimating Reliability in Mobile ad-hoc Networks Based on Monte Carlo Simulation (TECHNICAL NOTE)

Each system has its own definition of reliability. Reliability in mobile ad-hoc networks (MANET) could be interpreted as, the probability of reaching a message from a source node to destination, successfully. The variability and volatility of the MANET configuration makes typical reliability methods (e.g. reliability block diagram) inappropriate. It is because, no single structure or configurat...
