This paper investigates the resource allocation mechanism in infrastructure as a service (Iaas) cloud computing, in which the resources are offered in the form of virtual machine (VM) instances to users based on the pay-as-you-go model. We aim to maximize the profit of cloud service provider (CSP) meanwhile ensure that the resources are utilized efficiently. We exploit the auction-based model and...
For the problems of complex queries, load balance and routing efficiency in structured P2P networks based on DHT, a protocol is presented for text retrieval on the basis of Kleinberg small world model. In this protocol, nodes are clustered to support complex query according to the similarity of nodes, and the grouped nodes could adjust their size to balance the load of networks. Routing path length...
A critical problem of predicting the execution time of parallel programs is computing the maximum execution time of tasks involved in the parallel computation. For a parallel composition of n tasks, distribution information of execution time of the constituent task is crucial to accurately predicting mean, variance and even distribution of execution time of the composition of tasks when the execution...
