obs needing to be processed in a manufacturing plant, bank customers waiting to be served by tellers, aircraft waiting for landing clearances, and program tasks to be run on a parallel or distributed computer: What do these situations have in common? They all encounter the scheduling problem that emerges whenever there is a choice concerning the order in which tasks can be performed and the ass...

As the role of the computer as a communications device increases, we must reexamine the role an operating system plays in managing resources to support users. In support of general purpose computation, symmetric multiprocessing has generally proven better than attached processors, master/slave, or other conngurations. In this paper, we examine a diierent approach, Asymmetric Multiprocessor Oper...

A multi-threaded runtime environment which supports lightweight threads can be used to support many aspects of parallel processing including: virtual processors, concurrent objects, and compiler run-time environments. This work focuses on the area of compiler run-time environments. Such a library must depend on the underlying thread mechanism provided by the operating system. Threads working on...

VXS and VPX are emerging industry standards for embedded computing applications. Each has its own strengths, but both are based on standardized highperformance serial switched fabrics. Initial VXS and VPX products are targeted at performance-driven DSP and multiprocessing applications, having lots of digital signal processors, FPGAs, multicore, and/ or Cell processors. These boards also often s...

We present a real–time simulation of the phaco-emulsification task in a virtual reality training system for cataract surgery. Phaco–emulsification consists in breaking in small fragments and completely removing the eye crystalline lens by employing an ultra–sound tool called phaco–emulsificator. Our approach employs a mesh-less shape– based dynamic algorithm integrated with a simplex geometry r...

Software design is the process of mapping software functional requirements into a set of modules for implementation. In this paper, a new design technique called the concurrent software design technique (CSDT) is proposed. CSDT extends software design techniques, which are based on structured analysis and design, by identifying independent concurrent tasks for implementation in multiprocessing,...

In the mid-1990’s, Intel Corporation decided to use symmetric multiprocessing (SMP) in order to increase the number of instructions that could execute simultaneously by putting more than one processor on a motherboard. This idea increased the overall performance of a system, but it was too expensive for the average user to afford. Intel then looked into the idea of simultaneous multithreading (...

Although improved device technology has increased the performance of computer systems , fundamental hardware limitations and the need to build faster systems using existing technology have led many computer system designers to consider parallel designs with multiple computing elements. Unfortunately, the design of eecient and scalable multiprocessors has proven to be an elusive goal. This disse...

Real-time inspections for the large-scale solar system may take a long time to get hazard situations any failures that place in panels normal operations, where prior hazards detection is important. Reducing execution and improving system’s performance are ultimate goals of multiprocessing or multicore systems. video processing analysis from two camcorders, thermal charge-coupling devices (CCD),...

One of the infrastructure applications that cloud computing offers as a service is parallel data processing. MapReduce type processing used more and by data-intensive in environments. based on strategy called "divide conquer," which uses regular computers, also "nodes," to do parallel. This paper looks at how open multiprocessing (OpenMP), best shared-memory programming model for high-performan...
