Computational science simulations have been used to enable discovery in a broad spectrum of application areas, these show irregular demanding characteristics computing resources from time time. The adoption virtualized high performance cloud, rather than CPU-centric platform (such as supercomputers), is gaining interest interests mainly due its ease-of-use, multi-tenancy and flexibility. Basically, provisioning virtual cluster, which consists lot machines, real-time has critical impact on the successful deployment HPC clouds for computational simulations. However, cost concurrently creating many machines constructing cluster can be much two orders magnitude worse expected. One main factors this bottleneck spent create images machines. In paper, we propose novel technique minimize creation machine improve I/O provisioned clusters. We also confirm that our proposed outperforms conventional ones using various sets experiments.
