Grid Computing
projects with a focus on Grid Computing
Guaranteed delivery in Grids (GUARD-G)

The goal of this project on grid computing is to design and analyze techniques for delivering guaranteed service to applications in grids. The GUARD-G project is part of the GLANCE programme funded by NWO, and is performed jointly with Leiden University.

Handling Uncertainties in Large-Scale Distributed Systems (ALEAE)

The goal of ALEAE is to provide models and algorithmic solutions in the field of resource management that cope with uncertainties in large-scale distributed systems. ALEAE is a joint project of Delft University of Technology, INRIA in France, Osaka University in Japan, and the Zuse Institute in Berlin, Germany. One of the first purposes of ALEAE is to build the Failure Trace Archive (FTA), which is a centralized public repository of availability traces of parallel and distributed systems, and tools for their analysis. The purpose of this archive is to facilitate the design, validation, and comparison of fault-tolerant models and algorithms.

Virtual Laboratory for e-Science/KOALA
vl-e vl-e vl-e

In the Dutch national program Virtual Lab for e-Science (VL-e), we focus on resource management, scheduling, and performance analysis. In particular, we study the management and scheduling of jobs that require co-allocation, that is, the simultaneous allocation of resources (processors, data, etc.) in multiple subsystems making up a grid. For this purpose, we have designed and implemented the KOALA grid scheduler.

CoreGRID is a Network of Excellence of the European Union in grid computing, with 42 participating universities and public research institutes in Europe. CoreGRID is divided into six work package or so-called virtual institutes. One of these is the virtual institute on Resource Management and Scheduling, in which the PDS group participates.

Condor [finished]

In this project on grid computing, we focused on resource management across multiple sites. In particular, we designed and implemented the flocking mechanism in Condor for load sharing and job migration across different Condor pools, in cooperation with the main designer of the Condor system, Miron Livny.

Peer-to-Peer Computing
projects with a focus on Peer-to-Peer Computing
P2P-Fusion is an EU project on peer-to-peer systems for creative reuse of multimedia content in virtual communities. The project has seven partners in Finland, Hungary, and the Netherlands.

I-SHARE is a project on sharing technology at different levels in wired and wireless P2P systems. It is part of the BSIK programmme Freeband. As a guiding example, we are defining an architecture for P2P-TV, a P2P system for the dissemination of both live and recorded programs of 10,000+ TV channels. Research issues are how to do recommendations to users on TV programs, how to design the user interface, how to build application-level multicast trees for distributing live video, and in general, how to share the contents of individual video recordings on users' hard disks.

Two-level peer-to-peer systems

The research topic in this project is to exploit the heterogeneity of P2P systems, and in particular, to assess the performance impact of the presence of superpeers, which are peers that have more capabilities than other peers. We cooperate with the Large-Scale Distributed Systems group of the Vrije Universteit in Amsterdam in the Globesoul project.
