[Valgrind-users] Announcing new performance profiler: aprof

[Emilio C. <er...@gm...>]

Hi everyone,

We are developing a new Valgrind tool called aprof, a performance profiler
designed to help developers understand how an application’s performance
scales as a function of its input data. The tool automatically generates,
for each executed function, a 2D chart that relates performance to input
size, yielding clues to the "big Oh" of the underlying algorithm and
exposing possible asymptotic inefficiencies. Charts that analyze the input
workloads are also generated, among many others.

The tool and a profile visualizer have been brewing for some time and we
think they are mature enough to be released. For the time being, we're
keeping them at:

https://code.google.com/p/aprof

Please check the wiki for a manual and a brief tutorial explaining the main
goals of our profiler and how to use it. For an example of the kind of info
one can get from aprof see, e.g., Frank Reininghaus' blog

We would be happy to hear about any experience, difficulties, questions, or
suggestions about aprof.
Cheers,
Emilio
