چکیده

The paper is motivated by eciency considerations about porting mathematical software from Massively Parallel Processors (MPPs) to Networks of Workstations (NOWs). Heterogeneity of the network is the major obstacle to ef®cient porting: it can be overcome with a specialized system, Programming envIronment for Network of COmputers (PINCO), for monitoring available computational power at di€erent nodes, both statically and dynamically. The structure and functionalities of PINCO are outlined, and a signi®cant porting example, matrix multiplication, is presented. Ó 2000 Elsevier Science B.V. All rights reserved.

Homogeneous and Heterogeneous Networks of Workstations: Message Passing Overhead

On account of the growing number of workstations networks, many communication libraries are now also used outside the parallel computers area. Among those communication libraries, Message Passing Interface (MPI) appears to be an attempt of standardisation for distributed-memory computing systems. However, most people still prefer the other libraries, arguing about MPI's eeciency. The aim of our...

A resource management tool for heterogeneous networks

We describe the design principles and implementation of a tool to be used as Resource Manager on arbitrary networks of workstations. It evaluates both statically (offline) and dynamically (on-line) the computational power and workload of each node in the network, in order to select the most performant computers after each application request for task spawning to the network. The tool is a compo...

ECO: 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...

Parleda: a Library for Parallel Processing in Computational Geometry Applications

ParLeda is a software library that provides the basic primitives needed for parallel implementation of computational geometry applications. It can also be used in implementing a parallel application that uses geometric data structures. The parallel model that we use is based on a new heterogeneous parallel model named HBSP, which is based on BSP and is introduced here. ParLeda uses two main lib...

On Multicast Algorithms for Heterogeneous Networks of Workstations

Networks of workstations (NOWs) provide an economical platform for high performance parallel computing. Such networks may comprise a variety of different types of workstations and network devices. This paper addresses the problem of efficient multicast in a heterogeneous communication model. Although the problem of finding optimal multicast schedules is known to be NP-complete in this model, a ...
