An open market-based architecture for distributed computing
- Abstract. One of the challenges in large scale distributed computing is to utilize the thousands of idle personal computers. In this paper, we present a system that enables users to e ortlessly and safely export their machines in a global market of processing capacity. E cient resource allocation is

OmniStore: A System for Ubiquitous Personal Storage Management
- As personal area networking becomes a reality, the collective management of storage in portable devices such as mobile phones, cameras and music players will grow in importance. The increasing wireless communication capability of such devices makes it possible for them to interact with each other an

Investigating the Replica Transfer Scheduling Problem,” to appear
- The Replica Placement Problem (RPP) aims at selecting the nodes for duplicating data objects in order to optimize their access. Even though a lot of work already exists on RPP, the issue of implementing the resulting allocation scheme is typically overlooked. In this paper we introduce the Replica T

Market-driven Service Allocation in a QoS-capable Environment
- In this paper we describe a prototype that supports end to end QoS for applications invoking services over an ATM switch. The required resources are allocated to applications via auctions taking place in two independent markets. We investigate the effects of market independence in the behavior of th

Providing Support for Integrated Scientific Computing: Metacomputing Meets the Semantic Web and the Grid
- In this paper, we present an integrated system architecture for metacomputing on top of distributed scientific resources via active semantic-driven information management. Our approach is to consider both data and programs as objects of an applicationspecific ontology, describing them via correspond

Effects of an Asynchronous Resource Allocation Protocol on End-to-End Service Provision
- In this paper we present results of experiments that were performed to quantify the effects of retries in an asynchronous resource allocation protocol that is employed for end-to-end service provision. A major finding from our experiments is that an application class may be penalized by experienc
