This volume contains the proceedings of the International Symposium on C- puting in Object-Oriented Parallel Environments (ISCOPE 99), held in San Francisco, California, USA on December 8 10, 1999. ISCOPE is in its third 1 year, and continues to grow both in attendance and in the diversity of the s- jects covered. The original ISCOPE meetings and the predecessor conferences focused more narrowly on scienti?c computing in the high-performance arena. ISCOPE98 retainedthis emphasis, but broadenedto includediscrete-events- ulation, mobile computing, and web-based metacomputing. ISCOPE 99 cont- ues this trend. The ISCOPE 99 program committee received 41 submissions, and accepted 14(34%)asregularpapers, basedontheirexcellentcontent, maturityofdevel- ment, andlikelihoodforwidespreadinterest.Inaddition, theprogramcommittee selected six submissions as short papers. These papers were deemed to represent important workof a more specialized nature or to describe projects that are still in development. The 20 papers are divided into seven technical categories: Compilers and Optimization Techniques New Application Areas Components and Metacomputing Numerical Frameworks Generic Programming and Skeletons Application-Speci?c Frameworks Runtime Systems and Techniques This collection of 20 papers represents today s state of the art in applying object-orientedmethods toparallelcomputing.ISCOPE99istrulyinternational inscope, with its 52contributing authorsrepresenting21researchinstitutions in 8 countries.

This volume contains the Proceedings of the International Symposium on C- puting in Object-Oriented Parallel Environments (ISCOPE '98), held at Santa 1 Fe, New Mexico, USA on December 8{11, 1998. ISCOPE is in its second year, and continues to grow both in attendance and in the diversity of the subjects covered. ISCOPE'97 and its predecessor conferences focused more narrowly on scienti c computing in the high-performance arena. ISCOPE '98 retains this emphasis, but has broadened to include discrete-event simulation, mobile c- puting, and web-based metacomputing. The ISCOPE '98 Program Committee received 39 submissions, and acc- ted 10 (26%) as Regular Papers, based on their excellent content, maturity of development, and likelihood for widespread interest. These 10 are divided into three technical categories. Applications: The rst paper describes an approach to simulating advanced nuclear power reactor designs that incorporates multiple local solution - thods and a natural extension to parallel execution. The second paper disc- ses a Time Warp simulation kernel that is highly con gurable and portable. The third gives an account of the development of software for simulating high-intensity charged particle beams in linear particle accelerators, based on the POOMA framework, that shows performance considerably better than an HPF version, along with good parallel speedup.

This book constitutes the refereed proceedings of the First International Conference on Scientific Computing in Object-Oriented Parallel Environments, ISCOPE '97, held in Marina del Rey, California, in December 1997. The volume presents 36 revised papers carefully selected for inclusion in the book. The papers address run-time performance optimization at several levels, new language programming paradigms, applications of Java-based technology, direct applications in various areas, object-oriented libraries, and new ideas and approaches to parallel scientific computing. All in all, this is an up-to-date presentation of the state-of-the-art in the application of object-oriented methods in scientific and engineering applications.
