Open|SpeedShop: An Open Source Performance Analysis Framework for Cluster Platforms |
| Organizers: | Martin Schulz (Lawrence Livermore National Laboratory) Jim Galarowicz (Krell Institute) David Montoya (Los Alamos National Laboratory) |
Open|SpeedShop (O|SS) is an open source performance analysis tool for Linux clusters using IA64, IA32, EM64T, and AMD64 processors. It supports both large scale parallel applications based on MPI and multithreaded codes. O|SS offers multiple interfaces including a comprehensive graphical user interface and a textual command line interface. Further, O|SS is extensible offering a convenient platform for performance analysis tools research, development, and deployment.
The partnership between the Krell Institute and ASC/NNSA released Version 1.0 of O|SS in November 2006 under (L)GPL. O|SS is freely available for download from sourceforge in binary and source forms and is already in use at many sites.
In this tutorial we will introduce the attendees to O|SS with step-by-step instructions on how to apply it to real applications. We will cover O|SS’s comprehensive GUI as well as its ability to perform a wide variety of experiment types (including sampling and tracing). In the second half of the tutorial, we will then address more advanced issues like parallel performance analysis of MPI codes, the use of O|SS in scripting and batch environments, and the development of simple O|SS extensions and customizations.
