Description

PolyOpt/Fortran is a polyhedral loop optimization framework for Fortran, integrated in the ROSE compiler. The main features are:

  • Automatic extraction of regions that can be optimized in the polyhedral model
  • Full support of PoCC (the Polyhedral Compiler Collection) analysis and optimizations:
    • Dependence analysis with Candl
    • Program transformations for tiling and parallelism with Pluto
    • Code generation with CLooG
    • Parametric tiling with PTile
  • Numerous under-the-hood functionalities and optimizations

Note, only a subset of Fortran is currently supported by PolyOpt/Fortran: see PolyOpt/C for C/C++ programs support.

News

  • 03/09/2012: Release of the 0.1.0 version of PolyOpt/Fortran.

Documentation

Please note that the following document is preliminary. The documentation will be improved soon. In the meantime, don't hesitate to contact the author for any question.

PolyOpt manual: polyopt.pdf.


Installation

The installation of PolyOpt/Fortran is packaged in an installer script install.sh. It assumes ROSE is built, and will download and install a local copy of PoCC.

$> tar xzf polyopt-fortran-0.1.0.tar.gz
$> cd polyopt-fortran-0.1.0
$> export ROSE_ROOT=/path/to/rose/install
$> export BOOST_ROOT=/path/to/boost/install
$> ./install.sh
$> export PATH=$PATH:`pwd`/src


For a test run of the compiler:

$> PolyRose --polyopt-help
