CS Roofline Toolkit

Welcome to the CS Roofline Toolkit Bitbucket site. The Empirical Roofline Tool and Roofline Visualizer are currently available here. In the future additional tools will be hosted here. Please see the repository Wiki for additional information.

For an overview of the Roofline Performance Model and this software's place in that context see https://crd.lbl.gov/departments/computer-science/performance-and-algorithms-research/research/roofline/.

Empirical Roofline Tool

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).

This is version 1.1.0 of the ERT -- the second public release.

For details about the ERT, please refer to the User's Manual in the repository under the "Empirical_Roofline_Tool-1.1.0" directory.

Roofline Visualizer

The Roofline Visualizer can visualize the roofline performance data generated locally by the ERT or stored on a remote Roofline repository.

This is version 1.1.0 of the Roofline Visualizer -- the second public release.

For details about the Roofline Visualizer, please refer to the "README.md" file in the repository under the "Roofline_Visualizer-1.1.0" directory.
