Autotuning parameters/heuristics within gcc - best place to start?

[gfursin@gmail.com]

Hello,

Actually MILEPOST link is quite outdated. We now have a new 
python-based Collective Mind framework which includes universal 
multi-dimensional multi-objective auto-tuner with a web-based interface.

If you are interested, you may find some optimization flags and parameters 
for different versions of GCC in JSON format for this framework here:
http://c-mind.org/repo/?cm_menu=browse&browse_module_uoa=ctuning.compiler

The framework itself and our long-term vision is available here: 
http://c-mind.org

By the way, we are not advertising this framework much since it became
quite large in the past few years and includes many different proof-of-concept
plugins for our current work on reproducible experimentation and predictive modeling - 
therefore it's in our plans to release a lighter and simpler version at some point ;) ...

Hope it's of any help and take care,
Grigori

The Milepost project might also be of interest:
