Issues concerning optimistic time management on public-resource computing infrastructures and desktop grids are explored. The master/worker (MW) approach used for these platforms calls for a rethinking of optimistic synchronization and the development of new mechanisms and protocols specific to this paradigm. Approaches to rollback, message cancellation, state management and state saving are described...
The application of parallel and distributed simulation techniques is often limited by the amount of parallelism available in the model. This holds true for large-scale cell- biological simulations, afield that has emerged as data and knowledge concerning these systems increases and biologists call for tools to guide wet-lab experimentation. A promising approach to exploit parallelism in this domain...
Utilizing desktop grid infrastructures is challenging for parallel discrete event simulation (POES) codes due to characteristics such as inter-process messaging, restricted execution, and overall lower concurrency than typical volunteer computing projects. The Aurora2 system uses an approach that simultaneously provides both replicated execution support and scalable performance of PDES applications...
