Universal Adaptation Framework |
| Statically enabling run-time optimization and adaptation |
Navigation: cTuning.org > CTools UNIversal aDAPTation Framework (UNIDAPT) is the hybrid static/dynamic framework to enable low-overhead run-time adaptation, optimization and scheduling for unicore and heterogeneous multi-core architectures (GPGPU, CELL, etc) based on static function cloning (with explicit memory transfers if needed), dynamic monitoring routines and run-time decision trees based on static and dynamic program and dataset features. We are implementing this framework in GCC 4.4/4.5 combined with ICI (though maybe source-to-source adaptation framework can still be useful) within Google Summer of Code'09 program. We also hope to provide a unified view of heterogeneous architectures (CPU/GPU, CELL-like, FPGA, accelerators), optimizations and data movement/partitioning with a high-level abstraction layer (architectures, compilers, run-time systems) to automate and simplify program development and optimization for heterogeneous multi-core systems.    |
