Open XDMoD is an open source tool designed to facilitate the management of high-performance computing (HPC) systems. The Open XDMoD portal provides a rich set of analysis and charting tools that let users quickly display a wide variety of job accounting metrics over any desired timeframe. Two additional tools, which provide quality-of-service metrics and(More)
Machine learning techniques were applied to job accounting and performance data for application classification. Job data were accumulated using the XDMoD monitoring technology named SUPReMM, they consist of job accounting information, application information from Lariat/XALT, and job performance data from TACC_Stats. The results clearly demonstrate that(More)
The Technology Audit Service has developed, XDMoD, a resource management tool. This paper utilizes XDMoD and the XDMoD data warehouse that it draws from to provide a broad overview of several aspects of XSEDE users and their usage. Some important trends include: 1) in spite of a large yearly turnover, there is a core of users persisting over many years, 2)(More)
In this investigation, we study how application performance is affected when jobs are permitted to share compute nodes. A series of application kernels consisting of a diverse set of benchmark calculations were run in both exclusive and node-sharing modes on the Center for Computational Research's high-performance computing (HPC) cluster. Very little(More)
