Hi!

The library has method Simd::PrintInfo which prints system information about SIMD extensions used on current platform.

If you want to receive more detail information about acceleration received with Simd Library I would recommend to run Simd tests (see Test application).

An example to run tests:

./Test -m=a -tt=1

And you will receive a table with information about functions acceleration (see last columns).
