Planning-Based Scheduling for SLA-Awareness and Grid Integration

Service Level Agreements SLAs are powerful instruments for describing all obligations and expectations in a business relationship. It is of focal importance for deploying Grid technology to commercial applications. The EC-funded project HPC4U Highly Predictable Clusters for Internet Grids aimed at introducing SLA-awareness in local resource management systems, while the...

A Lightweight Linux Architecture for Resource-Limited Media Systems

Integrating multimedia processing into resource-limited computer systems (either stand-alone or part of a network environment) is more challenging than integrating it into traditional systems. With regards to multimedia applications, conventional systems have essentially limitless memory, non-volatile storage and computing power. Embedded devices are usually limited by at least one of...
