Contiguous allocation in multicomputers is useful for security and accounting reasons. In mesh-connected systems, it allocates each job an exclusive submesh of processors, and the allocated submesh has the same shape and size as that requested by the job. Because of this size and shape constraint, contiguous allocation typically suffers from high processor fragmentation. Processor fragmentation can...
The planning and effective usage of resources is a major challenge for organizations. More than ever through the global interconnections and the current economic situation the domain of resource allocation gains importance. Thus, within this paper we contribute to this research field by introducing a novel approach for dynamic activity and resource allocation using risk-aware business process simulations...
Because of highly dynamics, openness and autonomy of grid, effective access control mechanism is required to guarantee secure resource sharing on it. To resolve such problem, reputation and risk are formalized based on cloud model theory in this paper firstly. Subsequently, risk-aware reputation inference, combination and evolvement algorithms are designed respectively. Simulation results show higher...
Grids and peer-to-peer (P2P) networks have emerged as popular platforms for the next generation parallel and distributed computing. In these environments, resources are geographically distributed, managed and owned by various organizations with different policies, and interconnected by wide-area networks or the Internet. This introduces a number of resource management and application scheduling challenges...
