The benefits of virtualization are typically considered to be server consolidation, (leading to the reduction of power and cooling costs) increased availability, isolation, ease of operating system deployment and simplified disaster recovery. High Performance Computing (HPC) environments pose one main challenge for virtualization: the need to maximize throughput with minimal loss of CPU and I/O efficiency...
The article focuses on the development of a practical groupware system that allows each group member to modify a shared file unlike to traditional groupware systems in which updates from different users will conflict. The moderated collaborated mechanism maintains multiple copies of the shared object and also maintains one updateable copy of the shared content on each group member's node by introducing...
This paper describes the design and implementation of a group authoring system for wireless users. Our analysis of the behavior of various groupware systems using wireless user availability traces showed that prior systems would have performed poorly, especially during peak availability durations when many group members were simultaneously available. These results motivate our design choices. flockfs...
