With the development of grid computing, economy models are invented and increasingly applied, however, that is under the assumption of both transaction parties are honest and trustworthy. In reality there is serious information asymmetry between the transaction participators. Information asymmetry may cause resource providers opportunistically exploit the information gap for resource consumers on...
Massive multiuser virtual environments (MMVEs) are rapidly expanding both in the number of users and complexity of interactions. Their needs of computational resources offer new challenges for the computer scientists. In this paper we present some ideas on the implementation of a massive simulation environments, a particular MMVE, distributed over a peer-to-peer infrastructure. We analyze some of...
A remote desktop utility system is an emerging client/server networked model for enterprise desktops. In this model, a shared pool of consolidated compute and storage servers host users' desktop applications and data respectively. End-users are allocated resources for a desktop session from the shared pool on-demand, and they interact with their applications over the network using remote display technologies...
Multicore processors promise continued hardware performance improvements even as single-core performance flattens out. However they also enable increasingly complex application software that threatens to obfuscate application-level performance. This paper applies operational analysis to the problem of understanding and predicting application-level performance in parallel servers. We present operational...
