SESSION: The Future of the Open Trace Format (OTF) and Open Event Trace Recording

EVENT TYPE: Birds of a Feather

TIME: 5:30PM - 6:30PM

SESSION LEADER(S):Andreas Knuepfer, Felix Wolf


This BOF will discuss the latest plans for the evolution of the Open Trace Format (OTF) into version 2 and also present the design of a unified and open infrastructure for trace generation, profiling, and application instrumentation, OTF 2 will be embedded in. Since 2006, when it was first announced at the SC BOF "The Open Trace Format (OTF) and Open Tracing for HPC", OTF established itself as a community trace format adopted by many performance tools, ranging from smaller academic projects to those offered by larger vendors. The current open-source implementation of OTF includes a library with a stable API to read and write the format plus a number of command line tools. Although support for emerging architectures such as Cell and GPUs was added in the past, it has always retained backward and forward compatibility. The plans towards OTF 2 to be outlined during the BOF draw from the work of five academic research groups and include major enhancements such as increased performance and scalability, for example, after reducing the number of temporary files during trace recording to avoid file-system contention. Still, backward compatibility with OTF 1 will be preserved. In addition to OTF 2, there are related plans for a unified performance measurement infrastructure that will support tracing, profiling, and code instrumentation in one package. This will allow a larger number of tools to be used in combination with much greater ease, helping to exploit their full potential to the benefit of HPC users. All interested parties are cordially invited to join the discussion.
