Managing resources in large scale distributed systems is an important concern for both Peer-2-Peer and Computational Grid systems, and is a complex and time sensitive process. Although existing Peer-2-Peer systems are divided into those that support computation (CPU) sharing or data sharing, users in a Computional Grid generally need to share both. Identifying which resources to select is impor...

On-line connection provisioning with availability guarantees has to meet the double challenge of assigning resources to connections sparingly and ensuring that connection availability remains above a certain threshold. After having selected an appropriate protection scheme the first aim is achieved primarily by means of sharing backup resources, while the second aim calls for well-conceived res...

We argue that the resource sharing that is commonly manifest in semantic accounts of coordination is instead appropriately handled in terms of structure-sharing in LFG f-structures. We provide an extension to the previous account of LFG semantics (Dalrymple et al., 1993b) according to which dependencies between f-structures are viewed as resources; as a result a one-to-one correspondence betwee...

this paper highlights the strategic role of regional and national policies for digital libraries and archives in promoting access to knowledge for development in africa.  it views regional/national information policies as general frameworks and contexts within which policies for digital libraries and archives are situated.  it, however, recognizes the need to highlight the latter as instrument ...

One of the most important potential benefits of workstation clusters (client/server computing systems) is resource sharing. By interconnecting a number of workstations using a suitable network, a large number of hardware and software resources can be made available to users. In comparison with centralized computer systems (mainframes) and shared memory multiprocessors systems, the availability ...

Peer-to-Peer (P2P) computing is widely recognized as a promising paradigm for building next generation distributed applications, ranging from large scale scientific applications to mobile ad hoc information sharing, by federating dispersed pools of geographically distributed resources under loosely coordinated control. However, the autonomous, heterogeneous, and decentralized nature of particip...

Project Description Consulting on evaluation, purchase, installation, and use of software plays a prominent role in today’s software business. There are many attempts to replace human consultants by sophisticated help utilities, electronic wizards and elaborated Web sites. But they all have two major drawbacks: First, they cannot (yet) answer a specific question. They can only offer a database ...

Dissemination, reuse and sharing of digital resources is technically and culturally challenging in neuroscience – particularly in the area of Multi-Electrode Array (MEA) recording. Large, complex datasets are typical, with a heterogeneous range of data and code formats. The CARMEN project (http://www.carmen.org.uk/) aims to enable broad sharing or resources, through provision of a secure, onlin...

Since the formulation of the early ideas on meta-computing (Smarr & Catlett, 1992), several research activities have focused on mechanisms to connect worldwide distributed resources. Advances in distributed computing have enabled the creation of Grid-based resource sharing networks such as TeraGrid (Catlett, Beckman, Skow, & Foster, 2006) and Open Science Grid (2005). These networks, composed o...
