Empirical roofline tool (ERT) – a benchmark for machine performance characterization

A well known and very useful benchmark for characterizing a machine performance is the Empirical Roofline Tool (ERT).

The Empirical Roofline Tool, ERT, automatically generates a roofline data for a given computer. This includes the maximum bandwidth for the various levels of the memory hierarchy and the maximum gflop rate. This data is obtained using a variety of “micro-kernels”.

The ERT comes with a set of configuration files for a number of computers/architectures. These configuration file can be adapted to your local environment and needs to better measure the roofline parameters of your computer(s).

ERT source code can be found in bitbucket and github.
