摘要：In recent years, the use of public cloud platforms asinfrastructure has been gaining popularity in manyscientific areas and High Performance Computing(HPC) is no exception. These kinds of platformscan be used by system administrators as Test-Bedsystems for evaluating and detecting performanceinefficiencies in the I/O subsystem, and for takingdecisions about the configuration parameters thathave influence on the performance of an application,without compromising the performance ofthe production HPC system. In this paper, wepropose a methodology to evaluate parallel applicationsby using virtual clusters as a test system.Our experimental validation indicates that virtualclusters are a quick and easy solution for systemadministrators, for analyzing the impact of theI/O system on the I/O kernels of the parallel applicationsand for taking performance decisions ina controlled environment
