In this paper, we describe three contributions for distributed resource allocation in scientiic applications. First, we present an abstract model in which diierent resources are represented as tokens of diierent colors; in this model, processes acquire resources by acquiring tokens of appropriate colors. Second, we present distributed scheduling algorithms… (More)
Studies of queuing models with resequencing of jobs to keep the order at the output in the order of arrival are reviewed. A focus on recent authors results regarding optimal jobs assignment to heterogeneous servers is presented.
A procedure for calculating critical level and power of likelihood ratio test, based on a Monte-Carlo simulation method is proposed. General principles of software building for its realization are given. Some examples of its application are shown.
This document features informal reports by interns who spent the summer of 2000 working with researchers at Compaq Systems Research Center (SRC). The interns were graduate students in computer science or electrial engineering Ph.D. programs. Each worked for about three months at SRC, collaborating on a project with members of the research staff. The primary… (More)
We describe three contributions for distributed resource allocation in scientiic applications. First, we present an abstract model in which diierent resources are represented as tokens of diierent colors; processes acquire resources by acquiring these tokens. Second, we present distributed scheduling algorithms that allow multiple resource managers to… (More)
Most engineers use computational environments from the MATLAB family as a favorite tool for solving problems. The combination of being relatively easy to use and its might of calculations make it so attractive. A significant problem in solving more complex tasks is the time needed for obtaining results. Different approaches are used in order to reduce it to… (More)
The current paper presents a comparative analysis between numerical computer based methods applied towards modeling of thermal processes. The processes that are analyzed concern equipment based on electrical resistance heating - such as chamber resistive, blast and through furnaces. The study applies computer based modeling, using the finite element method… (More)
