PARDISC: a cost effective model for parallel and distributed computing
A homogeneous system of PCs, workstations, minicom-puters, etc. connected together via a local area network or wide area network represents a large pool of computational power. However, in a network of PCs and Workstations transparency is not provided, and hence, users are aware of other machines. PARDISC is a parallel programming environment, which provides the needed transparency as a scalabl...
متن کاملProfit-effective parallel computing
R esearchers widely use speedup, efficiency, and scalability1–3 to assess parallel-computing performance. These metrics encourage researchers to use any novel technique to design or improve a parallel system, without paying enough attention to the cost increase that such a technique incurs. However, as national-defense applications are downsizing, commercial applications are the dominant users ...
متن کاملCost-eeective Parallel Computing
Many academic papers imply that parallel computing is only worthwhile when applications achieve nearly linear speedup (i.e., execute nearly p times faster on p processors). This note shows that parallel computing is cost-eeective whenever speedup exceeds costup| the parallel system cost divided by uniprocessor cost. Furthermore, when applications have large memory requirements (e.g., 512 megaby...
متن کاملCost-Effective Parallel Tiled Display
This paper describes the CECA VisLab Tiled Display—a reconfigurable, multi-screen, multi-computer, distributed image display system with zoom and pan functions. The project software utilizes distributed computing algorithms to control a parallel system to render high resolution images and scientific data on multiple displays. The system extends open source software to provide a large tiled imag...
متن کاملCost-effective resource management for distributed computing
Current distributed computing and resource management infrastructures (e.g., Cluster and Grid) suffer from a wide variety of problems related to resource management, which include scalability bottleneck, resource allocation delay, limited quality-of-service (QoS) support, and lack of cost-aware and service level agreement (SLA) mechanisms. This thesis addresses these issues by presenting a cost...
