This paper compares two systems for parallel programming on networks of workstations: Parallel Virtual Machine (PVM), a message-passing system, and TreadMarks, a software distributed shared-memory (DSM) system. The eight applications used in this ...

We consider a network of workstations (NOW) organization consisting of bus-based multiprocessors interconnected by a high latency and high bandwidth interconnect, such as ATM, on which a shared-memory programming model using a multiple-writer ...

Networks of workstations and high-performance microcomputers have been rarely used for running parallel applications, because, although they have significant aggregate computing power, they lack the support for efficient message-passing and shared-...

Parallel applications can be executed using the idle computing capacity of workstation clusters. However, it remains unclear how to schedule the processors among different applications most effectively. Processor scheduling algorithms that were ...

Networks of workstations (NOWs) offer a cost-effective platform for high-performance, long-running parallel computations. However, these computations must be able to tolerate the changing and often faulty nature of NOW environments. We present high-...

This paper presents a hydrodynamic framework for solving the dynamic load-balancing problem on a network of heterogeneous computers. In this approach, each processor is viewed as a liquid cylinder where the cross-sectional area corresponds to the ...

We have explored methods for checkpointing and restarting processes within the distributed object migration environment (Dome), a C++ library of data parallel objects that are automatically distributed over heterogeneous networks of workstations (NOWs). ...

Load balancing involves assigning to each processor work proportional to its performance, thereby minimizing the execution time of a program. Although static load balancing can solve many problems (e.g., those caused by processor heterogeneity and ...

In this paper we discuss the runtime support required for the parallelization of unstructured data-parallel applications on nonuniform and adaptive environments. We describe several optimization techniques for fast remapping of data and for reducing the ...

The low cost and availability of clusters of workstations have lead researchers to re-explore distributed computing using independent workstations. This approach may provide better cost/performance than tightly coupled multiprocessors. In practice, this ...

The IBM System/390 Parallel Sysplex allows a parallel server to grow from a single system to a configuration of 32 systems, and appear as a single image to the end user and applications. It can provide capacity growth for today's largest commercial ...
