Efficient Collective Communication in Optical Networks
This paper studies the problems of One{to{All and All{to{All Communication in optical networks. In such networks the vast bandwidth available is utilized through wavelength division multiplexing: a single physical optical link can carry several logical signals, provided that they are transmitted on diierent wavelengths. In this paper we consider both single{hop and multi-hop optical networks. I...
متن کاملAn Efficient Collective Communication Method for Grid Scale Networks
This research is to design a collection of effective collective operations for the Grid scale network environment. In the Grid, several network features should be specified and adapted into the algorithmic design of collective operations. For this, we characterize the Grid and design hierarchical latency optimal tree algorithm for the MPI (message passing interface) library. The experimental re...
متن کاملEfficient Collective Communication on Heterogeneous Networks of Workstations
Networks of Workstations (NOW) have become an attractive alternative platform for high performance computing. Due to the commodity nature of workstations and interconnects and due to the multiplicity of vendors and platforms, the NOW environments are being gradually redefined as Heterogeneous Networks of Workstations (HNOW) environments. This paper presents a new framework for implementing coll...
متن کاملECO: Efficient Collective Operations for Communication on Heterogeneous Networks
PVM and other distributed computing systems have enabled the use of networks of workstations for parallel computation, but their approach of treating all networks as collections of point-to-point connections does not promote efficient communication—particularly collective communication. The Efficient Collective Operations package (ECO) contains programs which solve this problem by analyzing the...
متن کاملIncremental adaptive networks implemented by free space optical (FSO) communication
The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced the link coefficients using these distribu...
