Wei Huang from NCAR introduced a new tool which helps to get organized with FORTRAN codes. It greatly support a developer in understanding other people's codes and as well as identify design flaws in his own one.
It allows to easily visualize the call tree and module use. In addition it adds things like variable and function use counts.
Holger Brunst from the Technical University of Dresden showed how performance analysis data gathered on Cell code can be visualized and what information are available from it.
Implementing the same mathematical method for both, Cell and GPU platforms gives despite of the amount of work a deep insight on the performance differences especially under consideration that data has to be moved to and from the processing elements. Jose gave an analysis and comparison of how this affects his work
Godehard Sutmann from the Jülich Supercomputing Center (JSC) then gave an introduction into methods for simulating dilute solutions of polymers while taking into account hydrodynamic interactions.
This was followed by a talk about an implementation of parts of the outlined algorithms by Annika Schiller (also JSC). For realizing her project she applied the BSC's superscalar framework for Cell.
