We consider the problem of scheduling an application on a computing system consisting of
heterogeneous processors and data repositories. The application consists of a large number …

The scheduling of independent but file-sharing tasks on heterogeneous master-slave
platforms has recently found important applications in grid environments. The scheduling …

This paper proposes the idea of emulating fat-trees in overlays for multi-source multicast
applications. Fat-trees are like real trees in that their branches become thicker the closer one …

In this paper we propose a fault-tolerant scheduler for Bag-of-Tasks Grid applications, called
WorkQueue with Replication Fault Tolerant (WQR-FT), obtained by adding checkpointing …

Overlay-based multicast has been proposed as a key alternative for large-scale group
communication. There is ample motivation for such an approach, as it delivers the scalability …

Summary form only given. An important trend in scientific computing is the establishment of
computing platforms that span multiple institutions to support applications at unprecedented …

A Grid Information Service (GIS) stores information about the resources of a distributed
computing environment and answers questions about it. We are developing RGIS, a GIS …

One of the most important challenges of selforganized, overlay systems for large-scale
group communication lies in these systems ability to handle the high degree of transiency …

In this paper, we discuss a use case for employing Grid technology in a media
production/distribution environment. This type of environment is faced with the challenges of …

This chapter aims at contributing to a better understanding of generation and simulation
problems of the grid. Towards this end, we propose a new graph structure called layered …
