As Cloud Computing services become ever more prominent, it appears necessary to assess the efficiency of these solutions. This paper presents a performance evaluation of the OpenStack Could Computing middleware using our XDEM application simulating the pyrolysis of biomass as a benchmark.

A systematic study is presented, based on a fully automated benchmarking framework to evaluate three different configurations: native (i.e. no virtualization), OpenStack with KVM and XEN hypervisors. The authors' approach features the following advantages: real user application, the fair comparison using the same hardware, the large scale distributed execution, while being fully automated and reproducible.

Experiments have been run on two different clusters, using up to 432 cores. Results show a moderate overhead for sequential execution and a significant penalty for distributed execution under the Cloud middleware. The overhead on multiple nodes is between 10% and 30% for OpenStack/KVM and 30% and 60% for OpenStack/XEN.
