Cloud computing has emerged as an economical alternative to supercomputers for some of the high-performance computing (HPC) applications. Particularly suitable are applications that can scale without high-end interconnects; during testing; debugging; and for smaller-scale deployments. An increasing number of HPC users adopts hybrid deployments, where part of the resources are in-house and part of them are in the cloud. This raises the question of which platform is better for which applications, problem sizes, data sets, and scale. In this presentation, we explore the economical tradeoffs of running applications in the Cloud vs. on supercomputers. We characterize HPC applications running on platforms from dedicated supercomputers to commodity clusters, both in-house and in the cloud, and for different degrees of virtualization. We then propose mechanisms to match HPC applications to the best deployment platform. We analyze the performance-cost tradeoffs and show that careful mapping can substantially reduce the cost without incurring significant performance penalty.
