Vampir
Vampir is a framework for performance analysis, which enables developers to quickly study program behavior at a fine level of detail. Performance data obtained from a parallel program run can be analyzed with a collection of specialized performance views. Intuitive navigation and zooming are the key features of the tool, which help to quickly identify inefficient or faulty parts of a program code.
An important and unique feature of Vampir is its intuitive and interactive graphical representation of detailed performance event recordings over time (timelines) and as aggregated profiles. Extensive searching and filtering capabilities allow to quickly identify critical bottlenecks. In contrast to traditional profiling the details that caused a problem remain close at hand. The performance charts include rich sets of performance information and can be customized to the needs of both beginners and experts.
The scalable analysis backend VampirServer addresses very large performance analysis scenarios on supercomputers. Its objective is to ousource data intensive analysis operations from the Vampir user interface to powerful server hardware.
