Multiprocessors, whether mainframes or open systems, do not deliver linear-scaling capacity. The real capacity curve is sublinear due to some amount of processing capacity being usurped by the system in order to orchestrate the interaction between physical processors and computational resources. This computational overhead is sometimes referred to as the MP Effect (MPE) and its magnitude is det...

A new simulation tool for 3D simulation of fluid dynamics for liquids and gases is presented. The new version of Fluids6 supports multiprocessing, which considerably accelerates the simulation. The program includes en editor for 3D ducts with obstacles, holes, moving walls and internal temperature sources (in gas case). The external pressure pulse can be applied. Fluids6 provides various forms ...

Instruments for measuring the absorbed dose and rate under radiation exposure, known as dosimeters, are indispensable in space missions. They composed of sensors that generate current or voltage response when exposed to ionizing radiation, processing electronics computing rate. Among a wide range existing sensors, Radiation Sensitive Field Effect Transistors (RADFETs) have unique advantages mea...

Multiprocessor systems-on-chip (MPSoCs) open notable perspectives in the design of highly-targeted embedded solutions for real-time multitasking applications. The heterogeneity of available platforms, however, often hinders plain applicability of efficient scheduling policies, particularly in the case of loosely coupled architectures which do not provide any support for inter-processor tasks mi...

System-Level Modeling using system-level languages like SystemC or SystemVerilog is gaining more and more popularity. They are supposed to provide the garantee of critical functional properties about the interaction between concurrent processes like determinism or liveness up to a basic unit, the delta-cycle. Additionnally to this functional correctness, system level models should also provide ...

Computer architecture technology is moving towards more heterogeneous solutions, which will contain a number of processing units with different capabilities that may increase the performance of the system as a whole. However, with increased performance comes increased complexity; complexity that is now barely handled in homogeneous multiprocessing systems. The present study tries to solve a sma...

From the last two decades the trends in the Computing Industry is towards Distributed, low cost unit, and high unit volume product. Moreover software development activity is becoming more decentralized thereby expanding more development efforts for organizations. The performance of computing system has increased drastically with the inclusion of Multiprocessing and Multicomputing. This paper pr...

Performance enhancement for high speed computing can be carried out by using many techniques and architectures at software and high hardware level. Performance enhancement using hardware techniques may include the use of multiple computing nodes or a single node consisting of multiple processors. Symmetric multiprocessor is one of the modern architectures used to perform extensive computations....

ing system based on the Alpha 21164 64-bit RISC microprocessor. This midrange system supports one to four CPUs, one to four 64-bit-wide peer bridges to the peripheral component interconnect (PCI), and one to four logical memory slots. The goals for the AlphaServer 4100 system were fast CPU performance, low memory latency, and high memory and I/O bandwidth. One measure of success in achieving th...

This paper proposes the application of chaos in large search space problems, and suggests that this represents the next evolutionary step in the development of adaptive and intelligent systems towards cognitive machines and systems. Three different versions of chaotic simulated annealing (XSA) were applied to combinatorial optimization problems in multiprocessor task allocation. Chaotic walks i...
