SkelCL is a multi-GPU skeleton library based on OpenCL. It is actively developed at the University of Münster, Germany, by Michel Steuwer and others. For comments or questions feel free to contact the author: firstname.lastname@example.org Most of the functionality is explained in detail in the following peer-reviewed publications: - S. Breuer, M. Steuwer, and S.

Gorlatch: `SkelCL - A Portable Skeleton Library for High-Level GPU Programming' in 2011 IEEE International Symposium on Parallel and Distributed Processing Workshops and Phd Forum (IPDPSW), 2011, Anchorage, US Three key abstractions are made in this library: 1) memory management is simplified using parallel container data types (vectors and matrices); 2) an automatic data (re)distribution mechanism allows for implicit data movements between GPUs and ensures scalability when using multiple GPUs; 3) computations are conveniently expressed using parallel algorithmic patterns (a.k.a. algorithmic skeletons).
