The design and development of digital computer software for distributed concurrent programming environments has increased significantly in the past few years. The presence of remote processors and concurrency greatly complicates the creation, analysis, testing, and debugging of all software produced for these environments. It appears that few tools developed for sequential environments are adequate for debugging software programs in a distributed concurrent environment. The distributed concurrent environment also presents the need for special debugging tools that were not needed for sequential environments. This research will present a new model for debugging programs in a distributed concurrent programming environment. This new model was used to design, develop, and implement an integrated, cooperating set of concurrent debugging tools. The new debugging model and tool set were used in a distributed Concurrent C development environment running under the UNIX® operating system and connected by an Ethernet local area network. Actual results obtained from using the new debugging scheme and integrated debugging tool set to detect, locate, and correct software faults in distributed Concurrent C programs are also presented.

The book is divided into two parts, the first one covering the concepts and methodologies, and the second describing the tools and integrated environments that were developed in those projects. In this way, we hope that the reader will find the book useful not only concerning an identification of current trends in parallel program development, but also concerning their practical illustration through concrete tools and environments.

This set of technical books contains all the information presented at the 1995 International Conference on Parallel Processing. This conference, held August 14 - 18, featured over 100 lectures from more than 300 contributors, and included three panel sessions and three keynote addresses. The international authorship includes experts from around the globe, from Texas to Tokyo, from Leiden to London. Compiled by faculty at the University of Illinois and sponsored by Penn State University, these Proceedings are a comprehensive look at all that's new in the field of parallel processing.

LNCS volumes 2073 and 2074 contain the proceedings of the International Conference on Computational Science, ICCS 2001, held in San Francisco, California, May 27-31, 2001. The two volumes consist of more than 230 contributed and invited papers that reflect the aims of the conference to bring together researchers and scientists from mathematics and computer science as basic computing disciplines, researchers from various application areas who are pioneering advanced application of computational methods to sciences such as physics, chemistry, life sciences, and engineering, arts and humanitarian fields, along with software developers and vendors, to discuss problems and solutions in the area, to identify new issues, and to shape future directions for research, as well as to help industrial users apply various advanced computational techniques.
