Authors

  • beta versions, V1.0 (2006-2009):
    • Grigori Fursin (INRIA, France) - original design of the MILEPOST/ICI/cTuning framework
    • Mircea Namolaru (IBM Research Lab, Israel) - feature extractor pass

History

  • MILEPOST GCC 4.4.0 - 20090629 - New official version of MILEPOST GCC with new ICI v2.0 and updated static feature extractor.
  • MILEPOST GCC 4.2.2 - 20080613 - Stable MILEPOST GCC version used in most MILEPOST Year 3 experiments.

Requirements

In order to install MILEPOST GCC, you will need:

  • C compiler that can compile GCC 4.x.
  • uuid or uudigen tool to generate unique identifiers.
  • PHP (needed to communicate with cTuning web-services).

Directory structure

gcc-4.4.0                       - MILEPOST GCC 4.4.0 source directory (core + gfortran)
src-third-party                 - Third party support tools
 |     
 +-- gmp-4.3.0                  - GMP library
 +-- mpfr-2.4.1                 - MPFR library
 +-- ppl-0.10.2                 - PPL library (for GRAPHITE)
 +-- cloog                      - CLOOG library (for GRAPHITE)
 +-- XSB                        - Prolog for machine learning tools (MILEPOST, UNIDAPT, cTuning)
plugins-ici-2.0                 - Plugins for GCC 4.4.0 ICI 2.0 (see README inside this directory)
install                         - Directory with installed binaries

Installation

  • ./build_gcc.sh will build GCC with all the third-party tools.
  • ./build_plugins.sh will build all non-machine learning plugins.
  • ./build_plugins_ml.sh will build all machine learning plugins.

Now you can test the plugin system using self-explanatory tests in plugins-ici-2.0/tests directory.

Future work

It's now a community-driven project. You can find information
about extensions at http://ctuning.org/ici
Since 2009 we are working with GCC community to move parts 
of the ICI to the mainline.
