New electronic services rely on an increasingly sophisticated infrastructure composed of powerful servers, numerous fixed or mobile clients, and the system and networking software. The central processing units have evolved from simple processors, to symmetric multi-processors (SMP), non-uniform memory access (NUMA) SMPs and more recently multi-core (SMP on a single chip) systems. Embedded soft and hard real-time multi-core multi-computer systems are exceedingly difficult to debug and tune. Many problems, often timing related, only show under real loads, when the hardware (cache, page tables, synchronization) and software (operating system, virtual machines, libraries and applications) are interacting in real-time. The development time of distributed, online, applications is a major stumbling block for creating new services. Tools are needed to extract precise, globally ordered, debugging and performance data while minimizing the overhead on the systems under test. This data must be made available to suitable monitoring, visualization and analysis frameworks.
Experts from industry and university present the state of the art in the area of tracing/monitoring of computer systems, (including distributed and multi-core systems) and have advanced users present challenging problems they are facing. This should better adapt the R&D efforts in the area of diagnostic (security, reliability, accuracy, debugging, optimization, resource utilisation, timing behaviour) to the real priorities of industrial and governmental practitioners.
This event is held jointly by Ericsson, Defence R&D Canada and l’École Polytechnique de Montréal in preparation of a DND/NSERC R&D partnership project and the creation of an Eclipse tracing framework.
The representatives from each organization are:
- Michel Dagenais has been active in the area of system analysis tools for the past 15 years. The Linux Trace Toolkit, developed under his supervision at Ecole Polytechnique, is used throughout the world and gained the cooperation of a large number of industrial contributors over the years from Autodesk Media and Entertainment, Ericsson, Google, IBM, Monte Vista, Sony and others.

- Robert Charpentier after working at CAE Electronics on flight simulators, joined Canada Defense Research at Valcartier where he specialized in infrared imagery and space-based surveillance. His current research interests are in secure interoperability and software robustness.
Day 1 - Tuesday January 29, 2008
9h00-10h20 Michel Dagenais, Gabriel Matni, Pierre-Marc Fournier, Robert Roy
Survey of the best available tools and techniques for system performance tracing and analysis (part1, part2, part3, part4)
The talk will describe the different types of tools and techniques used to extract, analyze and visualize system execution and performance data. The survey will cover source level and binary instrumentation (e.g. Dtrace, SystemTap), as well as sampling (e.g. gprof, OProfile) for extracting data. Different visualization and analysis tools and frameworks will be described, including tools from the Eclipse framework, QNX and Wind River. As will be described by Robert Roy, for large parallel computing applications, the ultimate challenge of parallel performance analysis tools is to help in finding bottlenecks and synchronization problems and further optimizing the code. He will focus on the use of performance analysis tools for developing parallel solvers (inputs, ease of use, scalability).
10h30 – 10h50 Frank C. Eigler / RedHat
Description of the SystemTap free software infrastructure to simplify the gathering of information about running Linux systems. SystemTap eliminates the need for the developer to go through the tedious and disruptive instrument, recompile, install, and reboot sequence that may be otherwise required to collect data.
11h30 – 12h20 Robert Wisniewski / IBM
Performance analysis and debugging at IBM (slides)
Discussion of the performance analysis and debugging he has done at IBM. He will describe the challenges presented by both external and internal IBM clients, typically in the area of HPC and multi-core servers. He will then describe the tools he has worked on to address those challenges.
13h30-14h20 Eugene Chan / IBM - Eclipse Test & Performance Tools Platform
Extending Eclipse Test and Performance Tools Platform (TPTP) (slides)
Overview of the TPTP architecture following by a quick look at the profiling features of TPTP. Finally, we will focus on UI extensions that are available to support non-Java context.
14h30- 15h20 Steven Shaw / IBM Rational
IBM Rational Systems Developer Extensibility with consideration of UML Debug and Trace integrations (slides)
This presentation will provide a brief overview of the Rational Systems Developer tooling and then drive into the different extensibility features that it offers. The architecture of the product with respect to the open source components that it leverages will be explored as well as the relevant extensibility of those components. For example, we will briefly look at the extensibility mechanisms for Eclipse platform, EMF (Meta-model framework), UML2 (concrete meta-model built using EMF), GEF (Graphical Editing Framework), GMF (Graphical / Generative Modeling Framework), RSD (Rational Systems Developer). Finally we will create / examine some example plug-ins / plug-lets that utilize the extensibility with consideration of typical integrations that would be important for debugging a UML system.
15h30-15h50 Elena Zannoni / Oracle
Tracing at Oracle (slides)
Elena will talk about the experience of the Oracle DataBase team with tracing and the problems they face.

10h00 – 10h20 Henrik Thane / ZealCore
Monitoring, Information Fusion, Reverse Engineering and Replay Debugging (slides)
Discussion on different trace recording approaches including handling of multi-core systems, and most importantly what do you do with the recorded information? How can you fuse different trace logs, do reverse engineering and raise the level of Debugging? We will especially look into the problem on how to achieve forward and backward replay debugging on the UML model level (reanimated state-machines and sequence diagrams) based on reverse engineering of minimal target run-time recordings.
10h30-11h20 Beth Tibbitts / IBM Research
Eclipse Parallel Tools Platform & Performance Tools Framework (slides)
The Eclipse Parallel Tools Platform (http://eclipse.org/ptp) aims to produce an open-source industry-strength platform that provides a highly integrated environment specifically designed for parallel application development. This includes a standard, portable parallel IDE that supports a wide range of parallel architectures and runtime systems, a scalable parallel debugger, support for the integration of a wide range of parallel tools, an environment that simplifies the end-user interaction with parallel systems. A performance tools framework is being designed to ease the integration of performance tools into Eclipse and PTP. The University of Oregon has developed Eclipse plugins for PTP for its TAU (Tuning and Analysis Utilities) and we are working to generalize and make these features and others available to ease integration of other tools, including performance tools with PTP and EclipseParallel computing tracing with Eclipse Parallel Tools Platform Performance Analysis Framework / Tuning and Analysis Utilities.
12h30-13h20 Andrew McDermott / WindRiver
Developing OS-agnostic visualization tools (slides)
Today it is desirable to use a common [visualization] tool for diagnosing system behaviour. However, it is more common to find different tools, different user interfaces, different data formats and different levels of overall tool capability on a [operating] system-by-system basis. Additionally, the mechanics of querying the data in an ad-hoc manner outside the boundaries of the tool are typically programming language specific or non-existent. Wind River’s System Viewer, previously known as WindView, is a sophisticated visualization tool that enables developers to view the dynamic operation of their system. System Viewer has evolved to address the deficiencies listed above to be an OS-agnostic visualization tool (e.g., VxWorks and LTT), providing a separate and SQL-query able data engine that can accommodate new systems.
13h30-14h20 Felix Burton / WindRiver
Target Communication Framework (slides)
Today almost every device software development tool on the market has its own method of communicating with the target system. Communication methods often conflict with each other, requiring individual setup, configuration, maintenance, and imposes different limitations for different tools. TCF is designed to establish a common communication mechanism between development tools and embedded devices for the purposes of debugging, performance monitoring, file system access, etc.
Wind River Sensorpoint Technology (slides)
Increasingly complex systems are hard to debug using traditional techniques such as breakpoints and stepping or printf. Sensorpoints allow dynamic instrumentation of software in the lab as well as in the field with minimal impact on the system performance and system resources. This makes it ideal for diagnosing complex problems as well as creating patches to fix such issues in deployed devices. Sensorpoints are code fragments that can be dynamically “injected” into a binary image, without requiring a restart of the application or the device.
14h45-16h15 Michel Dagenais, Robert Charpentier, Dominique Toupin
Michel Dagenais, Robert Charpentier and Dominique Toupin will animate a discussion to identify the most important current and upcoming challenges for system analysis shared by the participants.
