ESODYP
ESODYP is a dynamic optimizer that models data accessing behaviour and prefetches the data in advance. It is a dynamic
predictor that builds a graph of memory strides and uses the graph to predict the next access strides.
This page is presentation of the system with links to a technical report (in french) and articles (in english) that
explain the system.
Finally, there is also a brief documentation of the framework that can be found here.

Download
For the moment, I admit the source code is in a single file and probably isn't the easiest thing to read. Good luck and don't hesitate to send me an email.
There will be at least 3 versions to the Esodyp framework, downloads will be put online as soon as I can find time to do it.
All the code has been put under the GPL Licence, send me an email for any questions/suggestions about the code...
- The stride version Download
- The version using the address values Download
- The version using a structure (easier to modify) Download
- The version using a manager with the stride version Download
Esodyp Viewer
Pierre-Yves HAEGY did a nice wxWidget interface that lets us create input configuration files and parses output files for the results of the model. Here's the link to the Esodyp Viewer.
