Scientific workflows (SWFs) play significant roles in scientific researches and engineering simulations, which are often data intensive and of complex data independency. The storage of the intermediate datasets has important impacts on the performance of SWF systems and, is very difficult to be determined. This paper analyzes the CTT-SP algorithm Yuan2011 that proposed for such problems to provide...
Data storage has great impacts on the quality of service of cloud computing systems. Storage of massive data in cloud environment is a very challenging problem. In this paper, we propose a multiobjective optimization model for massive data storage in cloud environment, in which the storage cost and reliability are considered simultaneously. The storage cost in the proposed model is considered to be...
