The Tracefile Testbed - A Community Repository for Identifying and Retrieving HPC Performance Data

HPC programmers utilize tracefiles, which record program behavior in great detail, as the basis for many performance analysis activities. The lack of generally accessible tracefiles has forced programmers to develop their own testbeds in order to study the basic performance characteristics of the platforms they use. Since tracefiles serve as input to performance analysis and performance prediction tools, tool developers have also been hindered by the lack of a testbed for verifying and fine-tuning tool functionality. We have created a community repository that meets the needs of both application and tool developers. In this paper, we describe how the Tracefile Testbed was designed to facilitate flexible searching and retrieval of tracefiles based on a variety of characteristics. Its Web-based interface provides a convenient mechanism for browsing, downloading, and uploading collections of tracefiles and tracefile segments, as well as viewing statistical summaries of performance charac...
