Optiflop measures the optimally achievable FLOPs for mathematical operations on various platforms.

Optiflop

A tool for measuring peak performance and roofline analysis.

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.
