Thomas Ludwig reveals design characteristics when aiming at researching information infrastructures and their diverse information resources, types of users and systems as well as divergent practices. By conducting empirically-based design case studies in the domain of crisis management, the author uncovers methodological and design challenges in understanding new kinds of interconnected information infrastructures from a praxeological perspective. Based on implemented novel ICT tools, he derives design characteristics that focus on integrating objective and subjective queried insights into situated activities of people as well as emphasizing the subjective nature of information quality.

This book constitutes the refereed proceedings of the Third European Conference on the Parallel Virtual Machine, EuroPVM '96, the 1996 European PVM users' group meeting, held in Munich, Germany, in October 1996.
The parallel virtual machine, PVM, was developed at the University of Tennessee and Oak Ridge National Laboratory in cooperation with Emory University and Carnegie Mellon University to support distributed computing. This volume comprises 51 revised full contributions devoted to PVM. The papers are organized in topical sections on evaluation of PVM; Applications: CFD solvers; tools for PVM; non-numerical applications; extensions to PVM; etc.

Beethoven reveals himself in his own writings.

This book presents new results in the construction and methodology of tools to support the development of parallel programs. It focuses on tools for debugging and performance analysis. We can observe two major trends in recent years: on one hand, tool developers want to solve the problem of tool interoperability. This question is crucial for application developers as they want to apply different tools from different producers to their programs at the same time. An infrastructure that provides interoperability could allow us to see synergetic effects when using multiple tools, thus increasing the programmer's productivity during implementation and testing. parallel program development. While this tool automation is not a new area, there remains much to be done. Parallel program development remains the domain of the expert and aficionado. This area continues to be an important one for the programmers and users of high performance computing.
