In this paper we discuss different aspects of system reconfiguration and their relation to the specific requirements from the application domain. Two projects – one from the video processing the other one from the IP networking domain – are introduced that make different use of runtime reconfiguration by either changing individual processing units or the logical interconnect structure of the sy...

 Abstract—Dynamic reconfiguration is essential part of software evolution. Several approaches to support dynamic reconfiguration have been proposed in the literature. These approaches are different in various criteria. The goal of this work is to make a comparative study between various dynamic reconfiguration approaches by exploring the features of these approaches and to classify them with r...

Open and dynamic characteristics of distributed software systems make user requirements and hardware resources change more rapidly, which make their evolution or reconfiguration inevitable, especially during their execution. A critical issue for those distributed systems is the specifying and analysis dynamic reconfiguration process of their architectures. In this paper, we proposed a method of...

Embedded systems normally involve a combination of hardware and software resources designed to perform dedicated tasks. Such systems have widely crept into industrial control, automotive, networking, and consumer products. These systems require efficient devices that occupy small area and consume low power. The device area can be minimized by reusing the same hardware for different applications...

Mating success in plants depends largely on the efficiency of pollen dispersal. For hermaphrodite plants, self-pollination, either within or among flowers, can reduce mating opportunities because of pollen and ovule discounting and inbreeding depression. Self-pollination may be particularly detrimental in plants such as orchids and asclepiads that package each flower's pollen into one or more p...

The Hidra Membership Monitor (HMM) is a distributed service that maintains the current set of active nodes in a cluster of machines. This protocol allows the detection of multiple machine joins or failures in a unique reconfiguration, using a low amount of messages (with a cost that is linear on the number of nodes). These membership services are needed to detect cluster changes as soon as poss...

Global vision consensus on the next generation of wireless mobile communications, broadly termed 4G, sketches a heterogeneous infrastructure, comprising different wireless access systems in a complementary manner and vested with reconfiguration capabilities that will facilitate a more flexible and dynamic adaptation of the wireless network infrastructure to better meet the ever-changing service...

A hardware mechanism has been proposed to reconfigure an interleaved memory system. The reconfiguration scheme is such that, at any instant, all fault-free memory banks in the memory system can be utilized in an interleaved manner. The design of the hardware that enables the reconfiguration is discussed. The reconfiguration scheme proposed in this paper is analyzed for a number of distinct benc...

In this paper, we describe DyRecT (Dynamic Reconfiguration Toolkit) a software library that allows programmers to develop adaptively parallel message-passing MPI programs for clusters of workstations. DyRecT provides a high-level API that can be used for writing adaptive parallel HPF-like programs while hiding most of the details of the dynamic reconfiguration from the programmer. In addition, ...
