IaaS clouds vs. clusters for HPC: a performance study
Church, Phillip and Goscinski, Andrzej 2011, IaaS clouds vs. clusters for HPC: a performance study, in Cloud Computing 2011 : The 2nd International Conference on Cloud Computing, GRIDS, and Virtualization, [IARIA], [Rome, Italy], pp. 39-45.
The increasing amount of data collected in the fields of physics and bio-informatics allows researchers to build realistic, and therefore accurate, models/simulations and gain a deeper understanding of complex systems. This analysis is often at the cost of greatly increased processing requirements. Cloud computing, which provides on demand resources, can offset increased analysis requirements. While beneficial to researchers, adaption of clouds has been slow due to network and performance uncertainties. We compare the performance of cloud computers to clusters to make clear the advantages and limitations of clouds. Focus has been put on understanding how virtualization and the underlying network effects performance of High Performance Computing (HPC) applications. Collected results indicate that performance comparable to high performance clusters is achievable on cloud computers depending on the type of application run.
