The Performance Evaluation Research Institute (PERI) is an Integrated Software Infrastructure Center (ISIC) for improving high-end computer performance. It was developed under the Department of Energy’s Scientific Discovery through Advanced Computing (SciDAC) program. The center is developing a science for understanding the performance of scientific applications on high-end computing systems. It develops engineering strategies for improving performance on these systems. The project integrates several active efforts in the high performance computing community and is forging alliances with application scientists working on DOE Office of Science missions to ensure that the resulting techniques and tools are truly useful to end users. The project focuses on how to best execute a specific application on a given platform.
PERI research emphasizes three areas: (1) performance modeling and prediction; (2) automatic performance optimization; and (3) performance engineering of high profile applications. The performance modeling and prediction activity develops and refines the performance models for given applications or computer systems, significantly reducing the cost of collecting the data upon which the models are based and increasing model fidelity, speed and generality. Spurred by the strong preference among HPC community, the institute is also devoting a large amount of activities in automatic tuning software research. The goal is to provide methodologies for automatic performance tuning that build upon our performance modeling and prediction techniques, and substantially reduce the performance burden on the application programmer. In addition, PERI also commits significant resources to application engagement by working directly with selected application projects, targeting performance improvements on large scale systems, and facilitating major scientific advances.
Power consumption and temperature dispassion are increasing challenges for large-scale systems. With tens to hundreds of thousands of processors, these systems consume megawatts of power, especially when executing computation-intensive DOE workloads. The RENCI team builds power and performance measurement infrastructure, and develops power management and scheduling techniques to adaptively reduce power demands with minimal effect on execution time. In addition, the team also investigates the probability of system failures due to large numbers of interacting components and develops a failure prediction toolkit that uses health measurement data to predict failures. Integrating the fault tolerances with performance and power optimization, the team applies multi-objective functions to balance the two objectives and creates prototype software for runtime performance tuning and adaptations for DOE codes.
