Tutorial: Open XDMoD – Providing comprehensive resource management for HPC Systems: Democratization of Access to HPC System Resource Use Information

The stakeholders of high performance computing (HPC) systems include users who run applications, application developers, support and consulting staff of HPC facilities, systems administrators, managers of HPC facilities and the funders of HPC facilities. Maximally productive use of these highly utilized and often oversubscribed systems, which enable computational and data intensive engineering and science, is important to all the above mentioned stakeholders. The recent availability of comprehensive resource use data at the job/core level enables a new data driven approach to systems design, optimization and management. The emerging domain of "data driven/data intensive" science can now be applied to management of HPC systems. With the framework described here, the execution behavior of all jobs on an HPC system can be characterized in terms of their resource use without the need to recompile the application code. This data can also be aggregated across many different sets of attributes including users, applications, application domains, "good" or "bad" resource use patterns, and is readily available through the XDMoD and Open XDMoD tools (XDMoD is specific for XSEDE resources while Open XDMoD is open source and available for any HPC center). XDMoD (and Open XDMoD) implements a very broad range of reports targeting the information needs of all stakeholder types.
The XDMoD system is or will be available on most or all major XD Net HPC resource providers including Stampede. Open XDMoD for academic and industrial HPC centers is available for download now. The information needs of all stakeholders in HPC systems ranging across individual users, developers of community codes, systems administrators and consultants, systems managers and facility funding agencies can thus all be systematically and comprehensively addressed.
