cTuning-related recent and upcoming events and news:

Collective Repository

Public repositories of knowledge about computer systems (big data)

Powered by Latest version Development years Current status Public access
cTuning3 repository aka Collective Mind (cM) beta 2012-cur. Active agile development; plugin-based framework; NoSQL based repository; json internal representation; powerful ElasticSearch indexing; universal auto-tuning and data mining; support for practically any Unix and Windows-based desktops, laptops, supercomputers, cloud servers, and even tablets and mobile phones with ARM,Intel,ST,Loongson,AMD,NVidia and other chips; powerful graph capabilities; BSD-style and LGPL license.

Since 2013, it is available on demand. Currently being tested and improved with several academic partners, and licensed to several industrial partners. Will be open for public at some point in 2013. Contact Grigori Fursin for more info.
cTuning1 platform (and CCC) 2.5 2006-2010 Stable, MySQL and NoSQL based. Development finished. Will be merged with cM. Used in multiple international collaborative projects including MILEPOST to develop the first machine learning enabled compiler. Link
cTuning2 repository aka CTI   2010-2011 Grigori Fursin and his group developed this repository for Intel Exascale Lab in 2010-2011 as presented at our BOF at SC'2011. Not available yet (mostly internal Lab/Intel use). Will have a very limited public access. Focus on Intel tools and architectures.
FCO repository   2003-2007 Stable, NoSQL based. Discontinued for CCC framework. Used in several collaborative projects (tuning Open64-based compilers for Loongson processor in collaboration with ICT, China). Discontinued for cTuning1/CCC framework.
EOS repository 2.2 1999-2006 Stable, NoSQL based. Discontinued for EOS framework. Used in MHAOTEU project. Discontinued for FCO framework.
SCS (SuperComputer Web Services) repository 1.3 1996-1999 Beta, MySQL based. Discountinued for EOS framework. Discontinued for EOS framework.

New collective research methodology and publication model for computer engineering

With our background in physics and AI, and a practical need to get efficient computer systems to solve our tasks, we are shocked by the current state of computer engineering. It is rare to find publications with reproducible and statistically meaningful results, systematized knowledge, open-source data and tools. One of the main reason is that sharing of data and tools simply doesn't pay off while the main focus is to publish as many papers as possible and to share as little data or tools as possible to avoid competition. However, since our aim to build efficient computer systems in terms of performance, power and reliability is to continue innovation in science, since 1996 we started a long-term and painful process of systematization of knowledge about design and optimization of computer systems through collaborative open-source tools and repositories. The first public repository have been used to enable machine learning self-tuning compiler - users ('crowd') have been searching effective predictive models to explain the behavior of computer systems preserved in the cTuning database. These models have been integrated with the MILEPOST GCC compiler or could be used as plugins for dynamic program adaptation (UNIDAPT framework).
