Behavioural Skeletons in GCM: Autonomic Management of Grid Components

Abstract. This paper describes the ParaPhrase project, a new 3-year targeted research project funded under EU Framework 7 Objective 3.4 (Computer Systems), starting in October 2011. ParaPhrase aims to follow a new approach to introducing parallelism using advanced refactoring techniques coupled with high-level parallel design patterns. The refactoring approach will use these design patterns to restructure programs defined as networks of software components into other forms that are more suited to parallel execution. The programmer will be aided by high-level cost information that will be integrated into the refactoring tools. The implementation of these patterns will then use a wellunderstood algorithmic skeleton approach to achieve good parallelism.A key ParaPhrase design goal is that parallel components are intended to match heterogeneous architectures, defined in terms of CPU/GPU combinations, for example. In order to achieve this, the ParaPhrase approach will map components at link time to the available hardware, and will then re-map them during program execution, taking account of multiple applications, changes in hardware resource availability, the desire to reduce communication costs etc. In this way, we aim to develop a new approach to programming that will be able to produce software that can adapt to dynamic changes in the system environment. Moreover, by using a strong component basis for parallelism, we can achieve potentially significant gains in terms of reducing sharing at a high level of abstraction, and so in reducing or even eliminating the costs that are usually associated with cache management, locking, and synchronisation.

“…In order to introduce the communication protocols definition we introduce now the considered pervasive grid approach proposed in (Aldinucci et al, 2008) and successively adopted in (CoreGRID Network of Excellence), where a distributed application can be modeled as a graph: the vertices are the logical components and the edges are the communication channels. The logical components of the application can be different, performing each one a specific set of operations on the input data.…”

Physical limitations on wireless communication channels impose huge challenges to reliable communication.Bandwidth limitations, propagation loss, noise and interference make the wireless channel a narrow pipe that does not readily accommodate rapid flow of data. Thus, researches aim to design systems that are suitable to operate in such channels, in order to have high performance quality of service. Also, the mobility of the communication systems requires further investigations to reduce the complexity and the power consumption of the receiver. This book aims to provide highlights of the current research in the field of wireless communications. The subjects discussed are very valuable to communication researchers rather than researchers in the wireless related areas. The book chapters cover a wide range of wireless communication topics.

“…ASSIST supports dynamic reconfiguration using a hierarchically structured application manager, which reconfigures the application based on availability of Grid resources. In GCM, components can contain Autonomic Managers that automatically perform reconfiguration based on dynamic measures, such as current performance [8]. Using this automatic reconfiguration, ASSIST and GCM applications perform dynamic load balancing.…”
