چکیده

We report the design and implementation of a callgraph profiler for GNU Octave, a numerical computing platform. GNU Octave simplifies matrix computation for use in modeling or simulation. Our work provides a callgraph profiler, which is an improvement on the flat profiler. We elaborate design constraints of building a profiler for numerical computation, and benchmark the profiler by comparing it to the rudimentary timer start-stop (tic-toc) measurements, for a similar set of programs. The profiler code provides clean interfaces to internals of GNU Octave, for other (newer) profiling tools on GNU Octave.

Spectutils, an Audio Signal Analysis and Visualization Toolkit for Gnu Octave Templates for Dafx-08, Finland, France Templates for Dafx04, Naples, Italy

Spectutils is a GNU Octave toolkit for analyzing and visualizing audio signals. Spectutils allows to display oscillograms, FFT spectrograms as well as pitch detection graphs. Spectutils can best be characterized as a user interface for GNU Octave, which integrates signal analysis and visualization functionality into dedicated function calls. Therefore, signal analysis with Spectutils requires l...

A Sample-Driven Call Stack Profiler

Call graph profiling reports measurements of resource utilization along with information about the calling context in which the resources were consumed. We present the design of a novel profiler that measures resource utilization and its associated calling context using a stack sampling technique. Our scheme has a novel combination of features and mechanisms. First, it requires no compiler supp...
