Many scenarios in medical research are predestined for grid computing. Large amounts of data in complex medical image, biosignal and genome processing demand large computing power and data storage. Integration of distributed, heterogeneous data, e.g. correlation between phenotype and genotype data are playing an essential part in life sciences. Sharing of(More)
In MediGRID a diverse spectrum of application scenarios from areas of bioinformatics, medical image processing, numerical simulations and clinical trials will be integrated into a Grid environment. In this paper we present the MediGRID infrastructure especially as required by medical image processing. Motivated by this selected application scenario the(More)
In order to clarify contradictory reports on the electrogenicity of sodium/L-glutamate cotransport, this cotransport was studied using brush-border membrane vesicles isolated from rabbit renal cortex. Beforehand, the claim that the symport of L-glutamate with Na+ is linked to simultaneous antiport with K+ has been confirmed by the demonstration that(More)
Instant-Grid (2006) provides an environment for demonstration, test and development of grid applications. Using a live-CD approach, cluster configuration and deployment of grid middleware is fully automated. The default installation of Instant-Grid results in a set of ready-to-use grid functionalities, which can be accessed in a beginner-friendly way via a(More)
—Contemporary workflow scheduling strategies that employ full-ahead planning of the complete workflow graph are typically designed for a resource model with high availability and good control over the resources by the scheduler. In production Grids with high utilization and autonomous sites, meta-scheduling is mostly focused on single jobs. Workflow(More)
—We describe four problems inherent to Grid scheduling that could be identified by means of measurements in the D-Grid. These problems make meta-scheduling nearly always a delicate task. In the face of this, we developed a new hybrid methodology to schedule application workflows which presumably supersedes existing methods. Our algorithm combines existing(More)
Infrastructure federation is becoming an increasingly important issue for modern Distributed Computing Infrastructures (DCIs): Dynamic elasticity of quasi-static Grid environments, incorporation of special-purpose resources into commoditized Cloud infrastructures, cross-community collaboration for increasingly diverging areas of modern e-Science, and Cloud(More)
