The proceedings from Parallel CFD 2006 covers all aspects of parallel computings and its applications. Although CFD is one of basic tools for design procedures to produce machineries, such as automobiles, ships, aircrafts, etc., large scale parallel computing has been realized very recently, especially for the manufactures. Various applications in many areas could be experienced including acoustics, weather prediction and ocean modeling, flow control, turbine flow, fluid-structure interaction, optimization, heat transfer, hydrodynamics.- Report on current research in the field in an ar

Over the past several years, embedded systems have emerged as an integral though unseen part of many consumer, industrial, and military devices. The explosive growth of these systems has resulted in embedded computing becoming an increasingly important discipline. The need for designers of high-performance, application-specific computing systems has never been greater, and many universities and colleges in the US and worldwide are now developing advanced courses to help prepare their students for careers in embedded computing.High-Performance Embedded Computing: Architectures, Appli

Chip multiprocessors - also called multi-core microprocessors or CMPs for short - are now the only way to build high-performance microprocessors, for a variety of reasons. Large uniprocessors are no longer scaling in performance, because it is only possible to extract a limited amount of parallelism from a typical instruction stream using conventional superscalar instruction issue techniques. In addition, one cannot simply ratchet up the clock speed on today's processors, or the power dissipation will become prohibitive in all but water-cooled systems. Compounding these problems is the simple fact that with the immense numbers of transistors available on today's microprocessor chips, it is too costly to design and debug ever-larger processors every year or two.

The last two years have been great for high performance computing in Baden- W¨ urttemberg and beyond. In July 2005, the new building for HLRS as well as Stuttgart’s new NEC supercomputer – which is still leading edge in G- many – have been inaugurated. In these days, the SSC Karlsruhe is ?nalizing the installation of a very large high performance system complex from HP, built from hundreds of Intel Itanium processors and more than three th- sand AMD Opteron cores. Additionally, the fast network connection – with a bandwidth of 40Gbit/s and thus one of the ?rst installations of this kind in Germany – brings the machine rooms of HLRS and SSC Karlsruhe very close together. With the investment of more than 60 Million Euro, we – as the users of such a valuable infrastructure – are not only thankful to science managers and politicians, but also to the people running these components as part of their daily business, on a 24-7 level. Sinceabout18months,therearelotsofactivitiesonallscienti?c,advisory, and political levels to decide if Germany will install an even larger European supercomputer, where the hardware costs alone will be around 200 Million Euro for a ?ve year period. There are many good reasons to invest in such a program because – beyond the infrastructure – such a scienti?c research tool will attract the best brains to tackle the problems related to the software and methodology challenges.

Design of modern digital hardware systems and of complex software systems is almost always connected with parallelism. For example, execution of an object-oriented p- gram can be considered as parallel functioning of the co-operating objects; all modern operating systems are multitasking, and the software tends to be multithread; many complex calculation tasks are solved in distributed way. But designers of the control systems probably have to face parallelism in more evident and direct way. Controllers rarely deal with just one controlled object. Usually a system of several objects is to be controlled, and then the control algorithm naturally turns to be parallel. So, classical and very deeply investigated model of discrete device, Finite State Machine, is not expressive enough for the design of control devices and systems. Theoretically in most of cases behavior of a controller can be described by an FSM, but usually it is not convenient; such FSM description would be much more complex, than a parallel specification (even as a network of several communicating FSMs).
