Or clone the project:

git clone https://github.com/mdesantis/rubystone

Usage

Use the rubystone executable (bin/rubystone if you cloned the project)

Translated from ADA to C by Rick Richardson. Every method to preserve ADA-likeness has been used, at the expense of C-ness.

Translated from Python to Ruby by Maurizio De Santis.

Changes

The Ruby version runs two indentical benchmarks sequentially, the cold run and the warm run: the latter is intended for platforms with JIT compilation (JRuby, Rubinius).
