Gaalop (Geometic Algebra Algorithms Optimizer) is a software to compile and optimize geometric algebra (GA) expressions into high-level programming language code. Geometric algebra expressions can be developed using the freely available CLUCalc software by Christian Perwass. Gaalop optimizes CLUCalc expressions and produces C++ (AMP), OpenCL, CUDA, CLUCalc or LaTeX output. The optimized code is free of geometric algebra operations and runs very efficiently on various platforms.
This is probably best explained in this article: https://slehar.wordpress.com/2014/03/18/clifford-algebra-a-visual-introduction/ or this book: http://www.amazon.de/Foundations-Geometric-Algebra-Computing-Geometry/dp/3642317936
Note that this repository also contains Gaalop Precompiler (GPC) in the branch gaalop_precompiler. GPC integrates Gaalop directly into CMake-generated C/C++-toolchains. Gaalop Precompiler reuses most of the code of Gaalop which is why merges from Gaalop are required quite often.
