OpenME

OpenME is a simple plugin-based event framework to decompose complex software (tools, applications) into interconnected and shareable plugins. It is also used to connect user programs written in any language to Collective Knowledge (CK) framework and enable plugin-based auto-tuning and run-time adaptation (see our publications below describing the concept).

Currently, we support interfacing with C, C++, Fortran, Java and PHP. Python is natively supported in Collective Knowledge framework.

The proof-of-concept (various auto-tuning version and Interactive Compilation Interface) has been successfully used in several academic and industrial projects since 1999, and has been eventually included to mainline GCC since version 4.6 (to enable interactive compilers and plugin-based auto-tuning combined with machine learning).

Java version of OpenME is used in Collective Mind Node to crowdsource compiler auto-tuning using mobile phones: https://play.google.com/store/apps/details?id=com.collective_mind.node

Note, that we currently updating this version to work with the new Collective Knowledge Framework. It may take some time, so please be patient!
