Abstract:
Observing the performance of an application at runtime requires economy in
what performance data is measured and accessed, and flexibility in changing
the focus of performance interest.
This paper describes the performance
callstack as an efficient performance view of a running program which can
be retrieved and controlled by external analysis tools.
The performance
measurement support is provided by the TAU profiling library whereas
tool-program interaction support is available through the DAQV
framework.
How these systems are merged to provide dynamic performance
callstack sampling is discussed.
