With the development at full speed of micro-processing and network technology, common network, such as the Local Area Network (LAN), is utilized to construct Cluster of Workstations (COW) by joining the high-performance workstations or top-grade PCs according to a certain structure. Base on COW, integrating modern communication technology and traditional parallel technology, a new knid of parallel technology—network paprallel computing is forming.
随着微处理技术和网络技术的飞速发展,可利用通用网络,如局域网(Local Area Network, LAN)将一组高性能工作站或高档PC 机,按某种结构连接起来而构建的工作站机群(Cluster of Workstations, COW)将现代网络通讯技术与传统并行计算技术结合起来,形成了一类新的并行计算技术——网络并行计算。
Otherwise,this thesis stressed to analyze the dynamic testing technology of Paradyn and the trace technology of AIMS,and compared them. And then,based on Cluster of Workstation architecture with ethernet network,we used the dynamic testing technology of Paradyn to design and implement a prototype of parallel monitor toolkit which supported BSP library.
Finally the result of test on share-nothing cluster of workstation show that after adopting the improved algorithm, execution performance and efficiency are higher than others. This result indicates that the algorithm has achieved algorithm optimization.
Based on footprint rendering method and according to the characterics of workstation clusters and volume data,this paper proposed a new dynamic load balance strategy of groupoftaskpools/groupofimages,and parallel rendering method of SupervisorWorkerCollector process. The results of theoretical analysis and numerical testing show:the dynamic load balance and parallel rendering method presented in this paper can improve parallel volume rendering efficiency effectively.
In order to realize distributed computing of Ada95, this paper discusses Ada95's distributed system model and an implement model of Ada95's distributed computing-workstation cluster model.
Parallel finite element method using domain decomposition technique is adapted to a distributed parallel environment of workstation cluster.
Using the developed code, a dam structural analysis problem is solved on workstation cluster and results are given.
Since the computing environment with many workstations on networks has recently become available, these workstations can be regarded as a virtual parallel computer, or a workstation cluster to perform finite element analyses.
The efficiency of these search procedures when executed on parallel systems is assessed by experimental results of a MIMD parallel implementation on a Meiko CS-2 and a workstation cluster.
Based on the PVM libraries, a platform-independent version has been developed for heterogeneous workstation clusters as well as for massively parallel computers.
This paper presents the development of a general-purpose parallel ocean circulation model, for use on a wide range of computer platforms, from traditional scalar machines to workstation clusters and massively parallel processors.
The improved performance and capacity of networks has made thecombined processing power of workstation clusters a potentiallypromising avenue for solving computationally intensive problems acrosssuch distributed environments.
We used the GUSTO testbed provided by the Globus metacomputing project as the source of the necessary state-of-the-art computational resources, including workstation clusters.
The resulting implementation is concise and gives excellent parallel performance on PC- and workstation clusters.
