This repository is supposed to contain some benchmarks
for various things. However, at this time of writing,
only a benchmark for the dot product in context of
artificial networks exists in the ann folder.
Look into the source and makefile for more explanations how to modify the examples.
In order to try out, just enter
$ make -C ann benchmark
On my computer, an i5-2540M equipped one, this leads to something like this:
