A Computing Capability Allocation Algorithm InDelicate Granularity For Cloud Environment

摘要

As several special features in the environment of cloud computing, which may be quite different from the centralized computing infrastructure currently available, the existed method of resource allocation used in the grid computing environment may not be suitable for these changes. In this paper, a new allocation algorithm based on Ant Colony Optimization (ACO) was proposed to satisfy the property of Cloud Computing. When started, this algorithm first predict the capability of the potentially available resource nodes;then, it will analyze some factors such as network qualities or response times to acquire a set of optimal compute nodes;finally, the tasks would be allocated to these suitable nodes. This algorithm met the needs of cloud computing with shorter response time and better performance than others which designed based on Grid environment. These were proved by the simulation in the Gridsim environment elaborated in the Session 3.
