چکیده
Abstract — Performance of parallel applications on networks of workstations can be different from that on a parallel machine. Therefore, it is important to understand the factors that influence the performance of parallel applications on this type of systems. To gain this understanding, we study the performance of a matrix multiplication application on a NOW-based system that uses the PVM. We have used a network of heterogeneous workstations, which are connected by two networks—the standard Ethernet (10 Mbps) and the Fast Ethernet (100 Mbps). These two networks allow us to study the effect of network speed on the performance. We report the impact of various system and workload parameters, mapping, and load sharing algorithms on the performance of the matrix multiplication application.

Application of Wavelet Neural Network in Forward Kinematics Solution of 6-RSU Co-axial Parallel Mechanism Based on Final Prediction Error
Application of artificial neural network (ANN) in forward kinematic solution (FKS) of a novel co-axial parallel mechanism with six degrees of freedom (6-DOF) is addressed in Current work. The mechanism is known as six revolute-spherical-universal (RSU) and constructed by 6-RSU co-axial kinematic chains in parallel form. First, applying geometrical analysis and vectorial principles the kinematic...
متن کاملA Slowdown Model for Applications Executing on Time-Shared Clusters of Workstations
ÐDistributed applications executing on clustered environments typically share resources (computers and network links) with other applications. In such systems, application execution may be retarded by the competition for these shared resources. In this paper, we define a model that calculates the slowdown imposed on applications in time-shared multi-user clusters. Our model focuses on three kin...

متن کاملA Comparative Study of Load Sharing on Networks of Workstations
Networks of workstations (NOWs) can be used for parallel processing by using public domain software like PVM. There are significant differences between a real parallel system and a NOW-based system. As a result, load sharing on a NOW can be different from that on a parallel machine. Therefore, it is important to understand the factors that influence the performance of load sharing algorithms on...
