Polly - Publications

http://polly.llvm.org/publications.html

LLVM Framework for High-Level Loop and Data-Locality Optimizations. Hexagonal tiling in 3D. Polly Labs Research Laboratory. Publications about polyhedral compilation. Has a large list of publications related to polyhedral compilation. They are very useful to get an idea of the latest developments in this area of compilation as well as to understand what kind of optimizations can be built on top of Polly. The canonical publication to cite Polly is:. Tobias Grosser, Armin Groesslinger, Christian Lengauer.

Polly - Performance

http://polly.llvm.org/performance.html

LLVM Framework for High-Level Loop and Data-Locality Optimizations. Hexagonal tiling in 3D. Polly Labs Research Laboratory. To evaluate the performance benefits Polly currently provides we compiled the Polybench 2.0. Benchmark suite. Each benchmark was run with double precision floating point values on an Intel Core Xeon X5670 CPU @ 2.93GHz (12 cores, 24 thread) system. We used PoCC. And the included Pluto.

Polly - Load Polly into clang

http://polly.llvm.org/example_load_Polly_into_clang.html

LLVM Framework for High-Level Loop and Data-Locality Optimizations. Hexagonal tiling in 3D. Polly Labs Research Laboratory. Load Polly into clang and automatically run it at -O3. Even though this example makes it very easy to use Polly, you should be aware that Polly is a young research project. It is expected to crash, produce invalid code or to hang in complex calculations even for simple examples. In case you see such a problem, please check the Bug database. And consider reporting a bug. To automatic...

Polly - Polyhedral optimizations for LLVM

http://polly.llvm.org/index.html

LLVM Framework for High-Level Loop and Data-Locality Optimizations. Hexagonal tiling in 3D. Polly Labs Research Laboratory. Polly is a high-level loop and data-locality optimizer and optimization infrastructure for LLVM. It uses an abstract mathematical representation based on integer polyhedra to analyze and optimize the memory access pattern of a program. We currently perform classical loop transformations, especially tiling and loop fusion to improve data-locality. Polly can also exploit O...The July ...

Polly - Getting Started

http://polly.llvm.org/get_started.html

LLVM Framework for High-Level Loop and Data-Locality Optimizations. Hexagonal tiling in 3D. Polly Labs Research Laboratory. Building and Installing Polly. There is a script. Available to automatically checkout, update, build, and test Polly. This script contains all the commands that are subsequently described on this webpage. The automatic installation consists of four simple steps:. Mkdir polly & cd polly wget http:/ polly.llvm.org/polly.sh chmod x polly.sh ./polly.sh.
