Performance studies on datacenter usage are usually limited (and perhaps even biased) due to the scale of the respective studies. In this paper, we present an extensive field study of several in-production datacenters that have been observed during a two-year time period. We present an extensive workload characterization study that sheds lights on the primary features of typical datacenter workloads,...
As a large-scale global parallel file system, Lustre file system plays a key role in High Performance Computing (HPC) system, and the potential performance of such systems can be difficult to predict because the potential impact to application performance is not clearly understood. It is important to gain insights into the deliverable Lustre file system IO efficiency. In order to gain a good understanding...
