  • A parallel computing model for the numerical solution of the general 20 shallow water equations in conservative form has been developed, tested and implemented in the MPI parallel environment set up on a parallel computer with four 2.8 GHz CPUs in Institute of Mechanics, VAST. The model is based on a Godunov-type numerical scheme, which is devised for 20 unstructured computational meshes, and on a domain decomposition technique.

  • Dictionary lookup is a computational activity that can be greatly accelerated when performed on large amounts of text by a parallel computer such as the Connection Machine T M Computer (CM). Several algorithms for parallel dictionary lookup are discussed, including one that allows the CM to lookup words at a rate 450 times that of lookup on a Symbolics 3600 Lisp Machine.

  • The study of parallel computing is just about as old as that of computing itself. Indeed, the early machine architects and programmers (neither category would have described themselves in these terms) recognised no such delineations in their work, although the natural human predilection for describing any process as a sequence of operations on a series of variables soon entrenched this philosophy as the basis of all normal systems.

  • Computational Fluid Dynamics, broadly encompassing fluid flows in engineering, atmospheric and ocean sciences, geophysics, physics and astrophysics, has seen calculations of great fidelity performed routinely that were only imagined at the inception of this conference series in 1989. These advances have not only been made with the available horsepower of increasingly more powerful parallel computers, but in tandem with advances in implementations of core and of entirely new algorithms, including multi-scale and adaptive methods....

  • This paper describes an efficient parallel system for processing Typed Feature Structures (TFSs) on shared-memory parallel machines. We call the system Parallel Substrate for TFS (PSTFS}. PSTFS is designed for parallel computing environments where a large number of agents are working and communicating with each other. Such agents use PSTFS as their low-level module for solving constraints on TFSs and sending/receiving TFSs to/from other agents in an efficient manner.

  • Single processor supercomputers have achieved great speeds and have been pushing hardware technology to the physical limit of chip manufacturing. But soon this trend will come to an end, because there are physical and architectural bounds, which limit the computational power that can be achieved with a single processor system. In this book, we study advanced computer architectures that utilize parallelism via multiple processing units.

  • Computer simulation has become an essential par t of science and engineering. Digital analysis of components, in particular, is important when developing new products or optimizing designs. Today a broad spectrum of options for simulation is available; researchers use everything from basic programming languages to various high-level packages implementing advanced methods. Though each of these techniques has its own unique attributes, they all share a common concern: Can you rely on the results?...
