In this paper we discuss the application of domain decomposition methods to circuit simulation. This coarse grain pamldelization guarantees low communication and thus achieves good speedup results on a workstation cluster. Especially with multi level Newton methods and iteration latency techniques, the communicatiolz can be reduced to a minimum. The application of these techniques make our para...

The network of workstations (NOW) we consider for scheduling is heterogeneous and nondedicated, where computing power varies among the workstations and local and parallel jobs may interact with each other in execution. An effective NOW scheduling scheme needs sufficient information about system heterogeneity and job interactions. We use the measured power weight of each workstation to quantify ...

A real-time tracking system was built to track performers on an interactive stage. Using an ordinary, up to date, desktop workstation, the performers’ silhouette was segmented from the background and parameterized by calculating the normalized central image moments. In the stage system, the silhouette moments were then sent to a parallel workstation, which used them to generate corresponding 3D...

The Cubi9000 family includes a range of products from the 3D graphics terminal up to the 3D graphics workstation. The Cubi9000 when configured as a 3D graphics terminal connects to a host computer via a parallel interface from Digital Equipment Corporation. The Cubi9000 configured as workstation includes a UNIX2 based mini-computer with a 32 bit microprocessor, mass memory, device handlers (mou...

In recent years, encouraged by today’s fast workstations and by software systems designed to transform workstation clusters into parallel programming environments, network of workstations have been increasingly used as computational engines. Networked workstations,however, are not ideal replacements for supercomputers, because of the low interconnection capacity provided by current local area n...

The advantages of workstation clusters as a parallel computing platform include a superior price{performance ratio, availability, scalability, and ease of incremental growth. However, the performance of traditional LAN technologies such as Ethernet and FDDI rings are insuucient for many parallel applications. This paper describes APACHE (Automated Pvm Application CHaracterization Environment) 1...

This paper presents the overview of parallel computer models. Practical parallel machines which are parallel virtual machine (PVP), symmetric multiprocessor (SMP), massively parallel processor (MPP), distributed shared memory (DSM), and clusters of workstation (COWs) are described. According to the classification of practical parallel machines, this paper mainly deals with distributed shared me...
