TL;DR: This paper describes the world's first real-time, international transmission of 4K digital cinema and 4K Super High Definition digital video at iGrid 2005, hosted at the California Institute of Telecommunications and Information Technology (Calit2) at the University of California, San Diego.

TL;DR: It is shown that by increasing the content availability of peers from their immediate neighbors, it can significantly improve system performance without trading off users' satisfaction.

TL;DR: A high-quality collaborative environment that uses High-Definition (HD) video to achieve near realistic perception of a remote site using a user-controlled UDP packet reflector based on the Active Element idea is described.

TL;DR: A case study of how BioSimGrid can be used for better storage, retrieval and analysis of biomolecular simulation data is introduced.

TL;DR: It is demonstrated how data locality and pipelining can achieve a significant percentage of the available huge computing power, and the influence of processor technology on recent and future numerical PDE simulation tools is explained.

TL;DR: A new compressible memory data structure for trace events is presented to aid the analysis of huge traces by reducing the memory requirements significantly and customized evaluation algorithms reduce the computational effort.

TL;DR: Six architectures that perform SLA auditing both quantitatively and qualitatively are evaluated, concluding that no single architecture seems to be the best solution for all cases and indicate where each one is best suited.

TL;DR: An ontology of CSCL tools that uses meaningful learning abstractions to describe them is proposed, which is the basis of a service discovery facility that is developed for allowing educators to search service-basedCSCL tools using learning concepts.
