About Optiflop

==============

Optiflop is a program for measuring the peak computational performance

(in FLOPs per second) and memory bandwidth on a compute node.  Tests are

written in C with a goal of portability.

Quick usage guide

=================

This is still a development branch, so the build process requires an extra step

or two.

1. Generate the ``configure`` script and ``Makefile``, then ``make``.::

      $ autoreconf

      $ ./configure

      $ make

To run for a default vector size (3200)::

   ./optiflop

For further options, ``optiflop --help``.
