Navigation: cTuning.org > CTools

The Interactive Compilation Interface (or 'ICI' for short) is a plugin system with a high-level compiler-independent and low-level compiler-dependent API to transform current compilers into collaborative open modular interactive toolsets. The ICI framework acts as a "middleware" interface between the compiler and the user-definable plugins. It opens up and reuses the production-quality compiler infrastructure to enable program analysis and instrumentation, fine-grain program optimizations, simple prototyping of new development and research ideas while avoiding building new compilation tools from scratch. For example, it is used in MILEPOST GCC to automate compiler and architecture design and program optimizations based on statistical analysis and machine learning. It should enable universal self-tuning compilers adaptable to heterogeneous, reconfigurable, multi-core architectures ranging from supercomputers to embedded systems.

Background:

Current development - source code repository, bug reports, discussions

Downloads

Plugin repository

Documentation and API - functionality, API reference guide, features, FAQ

User suggestions and feedback

Projects to extend ICI, plugins and compilers - more than 15 projects currently

ICI is an open collaborative community-driven project. You are welcome to join and participate in developments, discussions, provide feedback or suggestions to extend ICI or add new features. We develop ICI for GCC at the moment, but trying to keep it compiler independent in case someone would like to port it to other compilers to extend collaborative tools.

News

2009.April.27 - We gave a talk at the University of Illinois at Urbana-Champaign about Collective Tuning Initiative and tools and MILEPOST project ("Collective Optimization, run-time adaptation and machine learning"). Presentation is available here. We would like to thank all the UIUC colleagues for a very interesting and useful feedback.

2009.April.21 - Several projects to enable automatic fine-grain program optimization and run-time adaptation in GCC using iterative compilation and machine learning (based on our cTuning/UNIDAPT/ICI/MILEPOST technology) have been accepted by the Google Summer of Code. You are welcome to join cTuning community and follow or participate in the developments using our dedicated mailing lists.

2009.April.15 - Rice University made an announcement about a DARPA grant to improve compilers for heterogeneous architectures - this is yet another good motivation for our work since many similar techniques and open-source tools are already being developed by the cTuning community (cTools), within the MILEPOST project and HiPEAC network thus showing the power of collaborative R&D ;) ...

2009.Mar.24 - the new functionality implemented in the master branch on Gitorious was backported to a newly created gcc-4.2.4 branch to support and promote the use of ICI in production environments.

2009.Mar.20 - the master branch of the ICI framework was updated to SVN revision 144783 dated 2009-03-11 16:57:01.

2009.Mar.02 - Google Summer of Code'2009 will be accepting development applications soon - you are welcome to check ICI extension projects and ICI feedback/suggestion pages if you would like to help us to extend our collaborative tools within this program!

2009.Feb.27 - a GCC patch combining ICI-based high-level plugin infrastructure with low-level plugin infrastructure of GCC was submitted to the gcc-patches mailing list.

2009.Feb.13 - the comparison of Mozilla and ICI plugin APIs was uploaded to the GCC Wiki.

2009.Feb.9 - the master branch of the ICI framework was updated to SVN revision 144014 dated 2009-02-08 09:10:15.

2009.Feb.6 - the GCC Steering Committee agreed on the way plugins should be integrated into GCC. A new GCC Wiki page devoted to plugins was opened, and a dedicated "plugins" branch (svn://gcc.gnu.org/svn/gcc/branches/plugins) created in GCC SVN.

2009.Jan.12 - the result of a new SVN sync (SVN rev. 143113 dated 6 January 2009) has been uploaded to Gitorious. It fixes several performance issues which were introduced in GCC 4.3.x.
