HPC Application Performance and Cost Efficiency in the Cloud

Unlike traditional cluster systems, the Cloud Computing paradigm provides access to an execution environment without upfront investments in hardware and facilities. Due to the elasticity and the pay-per-use billing model, it is possible to configure experimental environments with minimal idle costs. In this paper, we perform an extensive evaluation of the major commercial public clouds. Our results show that performance degradation due to virtualization and other cloud overheads is insignificant. However, the network interconnection in the cloud still remains a large bottleneck for HPC application performance.
