high performance computing on graphics processing units: hgpu.org

Cloud computing setups are a huge investment of resources and personnel to maintain. As the workload on a system is a major contributing factor to both the performance of the system and a representation of the needs of system users, a clear understanding of the workload is critical to organizations that support supercomputing systems. In this paper, we analyze traces from two production level supercomputers to infer the characteristics of their workloads, and make observations as to the needs of supercomputer users based on them. We particularly focus on the usage of graphical processing units by domain scientists. Based on this analysis, we generate a synthetic workload that can be used for testing future systems, and make observations as to efficient resource provisioning.
