Abstract

Scientists are increasingly considering cloud computing platforms to satisfy their computational needs. Previous work has shown that virtualized cloud environments can have significant performance impact. However there is still a limited understanding of the overheads and the type of applications that might do well in these environments. In this paper, we detail benchmarking results that characterize the virtualization overhead and examine the performance of various interconnect technologies. Our results show that virtualization and less capable interconnect technologies can have a significant impact upon performance of typical HPC applications. We also evaluate the performance of the Amazon Cluster Compute instances and show that it performs approximately equivalently to a 10G Ethernet cluster at low core counts.
