Sensor networks open a new frontier for embedded-distributed computing. Paradigms for sensor network programming-in-the-large have been identified as a significant challenge toward developing large-scale applications....

The rise of SOA and PGAS doesn't quite spell the end of Corba, RMI, and other classic distributed-object systems, but it does increasingly restrict their ranges of use. These technologies surely still play major roles in enterprise-integration systems and heterogeneous intranet applications and niches such as real-time Corba, as well as the countless existing deployments that remain with us for years. They might even reemerge as the approach of choice in future grid computing frameworks that must sometimes straddle administrative domains. But the idea that one approach to object-oriented middleware could serve all needs seems to be one whose time has come and gone

The aim of this paper is to present a qualitative evaluation of two state-of-the-art Fortran-based parallel languages: OpenMP-Fortran and Co-Array Fortran (CAF). On the one hand, OpenMP-Fortran is an explicit parallel programming language. It designs for shared-memory architectures and extends the base-language by using compiler directives that annotate the original source-code. On the other hand, CAF is an implicit programming language. It designs for distribute-shared memory architectures and extends the base-language by new co-array constructs. We deconstruct each parallel language into its basic components, make a detailed analysis, compare them, and finally draw some conclusions.

In this paper, we develop conditions for the Takayama-Judge spatial equilibrium model to collapse into the classical Cournot model. In the case of heterogeneous demand and cost functions, the linear complementarity programming formulation is proposed to model the spatial Cournot model. Lastly, we implement the spatial equilibrium Cournot model to the US coal market and compare its performance to that of the original Takayama-Judge model. To the best of our knowledge, this is the only spatial equilibrium Cournot model estimated and implemented. (C) 2002 Elsevier Science B.V. All rights reserved.
Future high-end computers will offer great performance improvements over today's machines, enabling applications of far greater complexity. However, designers must solve the challenge of exploiting massive paralle...

It has been known for some time that groups as index domains of indexable container types provide a unified view for "geometric" (grids) and "hierarchic" (trees) spatial structures. This conceptual unification is the starting point of further generalizations. In this paper we present a new kind of index domains that combine both kinds of structure in a single index domain. Together with the "structured-universe approach", these new index domains constitute a framework for an expressive description of adaptive multi-grid discretizations and algorithms.

We describe here the design and performance of OdinMP/CCp, which is a portable compiler for C-programs using the OpenMP directives for parallel processing with shared memory. OdinMP/CCp was written in Java for portability reasons and takes a C-program with OpenMP directives and produces a C-program for POSIX threads. We describe some of the ideas behind the design of OdinMP/CCp and show some performance results achieved on an SGI Origin 2000 and a Sun E10000, Speedup measurements relative to a sequential version of the test programs show that OpenMP programs using OdinMP/CCp exhibit excellent performance on the Sun E10000 and reasonable performance on the Origin 2000, Copyright (C) 2000 John Whey & Sons, Ltd.
