Abstract:   Performance analysis and optimization of high-performance I/O systems is challenging. Mainly, this is due to the complex interplay of the involved hardware and software layers. The Scalable I/O for Extreme Performance (SIOX) project provides a versatile environment to monitor activities and research optimizations. The goal of SIOX is to assist in locating and diagnosing problems and to automatically apply optimizations, thus increasing performance-portability across sites. Our modular architecture covers instrumentations of POSIX, MPI and other high-level I/O libraries as well as server-side activities.
This BoF is split into three topics. First, a brief overview of the architecture and concepts is given. Next, technical presentations demonstrate how to instrument file systems and libraries to shed light on I/O behavior. Finally, we describe the modular concepts and how to employ SIOX as a laboratory simplifying I/O research.
Each topic will be illustrated with real-world examples, such as a set of primitive plug-ins to demonstrate the in-situ optimization of applications. Besides the presentations, we will foster a discussion on future directions of I/O monitoring among the attendees.

Targeted Audience
The technical presentations cover a wide range and target developers of tools, high-level I/O libraries and le systems as well as applied scientists and vendors.
