Simulation of Search and Distribution Methods for Jobs in a WEB Operating System (WOS)

Unger, Herwig ; Kropf, Peter ; Babin, Gilbert ; Böhme, Thomas

In: High Performance Computing Symposium 98, 2008, p. 253-259

Internet or WEB computing concepts, such as the Web Operating System (WOS™), require suitable methods for finding the most effective hardware and software environment for an application execution on the network. We present an efficient search strategy and show that the resulting communication load penalty is well acceptable while preventing the network from being flooded by administrative...

Overview About the Resource Scheduling in the Web Operating System (WOS)

Unger, Herwig ; Kropf, Peter

In: Proceedings of the Workshop on Distributed Computing on the Web (DCW’98), 1998, p. 134-140

A number of load sharing/balancing mechanisms were developed in order to improve the execution of a distributed application in a workstation cluster or any other kind of distribute darchitectures. In fact, it would be possible to execute applications on any machine of a world wide system. However, the notion of ‘distributed systems’ has gained in importance and attraction with the...

Simulation of communities of nodes in a wide area distributed system

Yuen, Saiho ; Kropf, Peter ; Unger, Herwig ; Babin, Gilbert

In: 4th EUROSIM Congress, 2001, p. 1-6

The complex structure of the Web requires decentralised, adaptive mechanisms efficiently providing access to local and global capacities. To facilitate the development of such mechanisms, it seems to be reasonable to build clusters or grids of machines with similar structures and interests. In such a manner, communities of machines can be built. In a community, every machine contributes to the...

Two-Level Communication Protocol for a Web Operating System (WOS)

Babin, Gilbert ; Kropf, Peter ; Unger, Herwig

In: Euromicro Workshop on Network Computing, 1998, p. 939-944

The World-Wide Web consists not only of informational, but also computational resources. However, these resources, especially computational ones are underutilized. One characteristic of theWeb is its ever changing structure; for instance, nodes are dynamically added and removed. This makes it difficult, if not impossible, to draw a complete and accurate picture of available resources. We consider...

WOS: an Internet Computing Environment

Kropf, Peter ; Unger, Herwig ; Babin, Gilbert

In: Workshop on Ubiquitous Computing, IEEE International Conference on Parallel Architecture and Compilation Techniques, 2000, p. 1422-1430

Given the current development of the Internet, the Web, mobile communications and services, we are clearly head- ing towards an era of widely integrated ubiquitous services sharing some kind of global operating system. This arti- cle describes the idea, the objectives and the current state of the development of the WOS-project. The Web Operat- ing System (WOS") consists of a series of versioned...

Message Chains and Disjunct Paths for Increasing Communication Performance in Large Networks

Wulff, Markus ; Kropf, Peter ; Unger, Herwig

In: Lecture notes in computer science (LNCS), 2000, vol. 1830, p. 122-132

In this paper we propose a simple powerful method to increase communication performance in large networks such as the Internet. Our approach is based on the usage multiple disjunct paths for the transmitting data from one node to another one. The method exploits the dense connectivity of the Internet by making use of the different routes engaged in communications originating from different nodes...
