We would like to add common API to current simulation platforms such as UNISIM and SimpleScalar, for example. We would like to connect simulators with the ICI-enabled compilers and Collective Optimization Database to enable research on joint software/hardware optimizations.

This project has not started yet. You are welcome to join us and leave suggestions below or participate in this project.

News
  • 2010.April.28 - Discussion page about GCC as a research compiler has been updated; Google Summer of Code'10 projects for GCC has been announced; project to modularize GCC has been proposed by Diego Novillo.
  • 2010.April.14 - Long awaited GCC 4.5 has been released! It features new plugin framework with some parts of ICI to continue GCC modularization and parametrization, simplify pass manipulation and reordering, and enable better integration with cTuning/MILEPOST tools to automate optimization space exploration and prediction of profitable combinations of program transformations during multi-objective optimizations (balancing execution time, code size, compilation time, etc) for a given program/dataset/architecture.
  • 2010.March.17 - We pre-released all tools including MILEPOST GCC, CCC framework, cBench and cDatabase. It's a major update of cTuning tools including changes behind to support transparent optimizations of programs and libraries, better multi-objective optimization (including balancing of execution time, code size and compilation time), bug fixes in averaging multiple optimization cases, C++ support in MILEPOST GCC, support of all version of GCC 4.4, new static features in MILEPOST GCC, extended documentation, etc. Feedback and comments are welcome here.
  • 2010.March.01 - CGO'10 program is available on-line.
  • 2010.January.28 - Proceedings and slides from GROW'10 and SMART'10 are now available online.
  • 2010.January.4 - Call for participation: GROW'10 and SMART'10 workshops will be held on the 23rd and 24th of January in Pisa, Italy co-located with the HiPEAC conference. Preliminary programs are available: SMART'10 program and GROW'10 program.
  • 2010.January.1 - We wish you all a very happy and prosperous New Year with lots of exciting achievements maybe even related to cTuning technology ;) !
  • 2009.November.11 - Small CCC analysis plugins update available at SVN to speedup queries when dealing with large amount of optimization data in cDatabases (gigabytes of data).
  • 2009.November.7 - Submission deadline for SMART'10 workshop has been extended until the 22nd of November, 2009.
  • 2009.October.2 - We successfully passed the final MILEPOST review and the project is officially over. We would like to thank all the partners from the University of Edinburgh, IBM Haifa, CAPS and ARC for a great collaborative work during last 3 years and cTuning community for a very interesting feedback and extensions! We released all the tools from the project and hope to continue extending them within community-driven cTuning.org. This infrastructure should open up many interesting research opportunities for performance auto-tuning based on statistical and machine learning techniques so we hope to see many more interesting extensions to the MILEPOST/cTuning technology soon ;) !..
  • 2009.September.25 - New CFP for SMART'10 workshop co-located with HiPEAC'10 conference in Pisa, Italy is now available. Prof. Keith Cooper from Rice University kindly agreed to give a keynote talk.
  • 2009.September.22 - Congratulations to Dr.Christophe Dubach who has won a presitigious BCS/CPHC Distinguished Dissertation Award for his thesis "Using Machine-Learning to Efficiently Explore the Architecture/Compiler Co-Design Space" supervised by Prof. Michael O'Boyle. This topic is related to cTuning technology!
