Towards a Community Infrastructure With and Around Open|SpeedShop

Open|SpeedShop (O|SS) is an open source performance analysis toolset for Linux clusters using IA64, IA32, EM64T, and AMD64 processors. It supports both large scale parallel applications based on MPI and multithreaded codes and offers multiple interfaces including a comprehensive graphical user interface and a textual command line interface.  However, despite its comprehensive functionality, it only represents one point in the space of tools that will be necessary to successfully support code development on current and future large scale machines.  Nevertheless, many of its components are generally applicable (often taken or adapted from other open source projects) and could be shared among a large number of tools.  This would not only reduce the effort necessary to design and implement new tools, but would also focus the joint development to few highly stable and robust components.

We will use this workshop to explore what components of Open|SpeedShop could be useful for a larger community, how they should be adapted to be more generally applicable, which other existing components or tools should be included in such a community infrastructure, and which capabilities are still missing to be able to provide scalable tools for next generation machines.  It is our hope that this workshop will help foster collaborations and drive future collaborative developments in this area.

The workshop will consist of a set of presentations from groups that are building scalable tools highlighting how they envision a larger cross-tool community infrastructure and what they expect from it.  This will be followed by discussions on how such tools could be combined, what kind of interfaces already exist and what additional components would be necessary to achieve true tool interoperability.
