This paper presents an implementation of MPI on a cluster of Linux-based, dual-processor PCs interconnected by a Myricom high speed network. The implementation uses MPICH for the high level protocol and FM/HPVM for the basic communications layer. It allows multiple processes and multiple users on the same PC, and passes an extensive test suite. Execution times for several application codes, ranging...
Recently, a new class of mobile applications has appeared that takes into account the behavior of physical phenomenon. Prominent examples of such applications include augmented reality applications visualizing physical processes on a mobile device or mobile cyber-physical systems like autonomous vehicles or robots. Typically, these applications need to solve partial differential equations (PDE) to...
A cluster of commodity computers and general-purpose computers with accelerators such as GPGPUs are now common platforms to solve computationally intensive tasks like scientific simulations. Both technologies provide users with high performance at relatively low cost. However, the low bandwidth of interconnect compared to the computing performance hinders efficient operation of both cluster and accelerator...
This is a companion paper to a paper of the same title, Part I. In the Part I paper, it was proposed that a centralized control system be established to coordinate some selected dispersed generators (DGs) in a distribution system for providing the usual energy service as well as some ancillary services, such as reactive power control, load following, and compensation of continuous PQ disturbances...
Reliability is very important for the systems in aeronautics and astronautics. Despite its appeal for attractive mathematical features the PLP model suffers from a few drawbacks. Duane and Crow/AMSAA models are widely used in the reliability growth assessment. But for the reliability growth case, the intensity function of the PLP has the rather unrealistic feature that it tends to infinite as time...
The paper discusses the problem of reliability evaluation of power system devices subjected to transient overvoltages. The problem is solved in the framework of "stress-strength" models, resorting to a few simplifying hypotheses, among which that a certain degree of knowledge is available about the degradation of component insulation strength with time and about the pdf of stress (overvoltage)...
