OSL -- Orléans Skeleton Library
OSL, the Orléans Skeleton Library provides a set of data parallel skeletons which follow the bulk synchronous parallel (BSP) model of parallel computation. OSL is a library for C++ currently implemented on top of MPI and it uses meta-programming techniques to offer a good efficiency. Our goal is thus to provide an easy to use library for a widely used programming language and that allows simple reasoning about parallel performances based on a simple and portable cost model.
Support
Work on OSL is supported by the Agence Nationale de la Recherche in the program ANR Blanc International, project Parallel Program Development with Algorithmic Skeletons (PaPDAS) and by the SPEED project funded by the Conseil Général du Loiret.
