Abstract: Grids are becoming mission-critical components in research and industry, offering sophisticated solutions in leveraging large-scale computing and storage resources. Grid resources are usually shared among multiple organizations in an opportunistic manner. However, an opportunistic or "best effort" quality-of-service scheme may be inadequate in situations where a large number of resources need to be allocated and applications which rely on static, stable execution environments. The goal of this work is to implement what we refer to as quasi-opportunistic supercomputing. A quasi-opportunistic supercomputer facilitates demanding parallel computing applications on the basis of massive, non-dedicated resources in grid computing environments. Within the EU-supported project QosCosGrid we are developing a quasi-opportunistic supercomputer. In this work we present the results obtained from studying and identifying the requirements a grid needs to meet in order to facilitate quasi-opportunistic supercomputing. Based on these requirements we have designed architecture for a quasi-opportunistic supercomputer. The paper presents and discusses this architecture. more

Abstract: due to several reasons such as attentions given to design features and to modification from littler to medium sized system that results in trivial enhancement in performance.In spite of the tremendous achievement of grids which run parallel jobs, there still exists demand of requesting applications to avail opportunistic computing for considering the right selection of prerogative supercomputers. The objective of this research is to build a framework for on the fly computational commencing on socially convolved terrestrial grids to facilitate the sharing of computing workload over wireless networks as virtual supercomputers of unprecedented power. This will assist computing in heterogeneously interconnected mobile assets, Internet of Things, in crowdedscenarios for variable ranges like: stadiums, shopping centers, and so forth. more

Abstract: The ultimate vision of grid computing are virtual supercomputers of unprecedented power, through utilization of geographically dispersed distributively owned resources. Despite the overwhelming success of grids there still exist many demanding applications considered the exclusive prerogative of real supercomputers (i.e. tightly coupled parallel applications like complex systems simulations). These rely on a static execution environment with predictable performance, provided through efficient co-allocation of a large number of reliable interconnected resources. In this paper, we describe a novel quasi-opportunistic supercomputersystem that enables execution of demanding parallel applications in grids through identification and implementation of the set of key technologies required to realize the vision of grids as (virtual) supercomputers. These technologies include an incentive-based framework basic on ideas from economics; a co-allocation subsystem that is enhanced by communication topology-aware allocation mechanisms; a fault tolerant message passing library that hides the failures of the underlying resources; and data pre-staging orchestration. more
