Presentation tools for performance visualization: the M31 instrumentation experience
M.H. Reilly · 2002
The performance analysis tools developed for M31, Digital Equipment Corporation's experimental multiprocessor, are described. The tools allow a user to instrument an application, monitor its execution, and analyze the collected event traces. The analysis and presentation tools give a view of the application's dynamic call tree as well as the flow of control within and between cooperating processes. The trajectory of a scientific application is described through the performance debugging process.>
