liftracc is a library framework to create accelerated replacements of existig

libraries. The new library can be used instead of the old, unaccelerated

version. One technique to use such libraries is 'shared library interposing'.

Through a flexible plugin system it is possible to integrate existing versions

of accelerated sublibraries. Also it is possible to write the needed

programmcode directly inside a plugin to control the hardware accelerator

(e.g. grafik card, accelerator board).

The framework provides mechanisms to dynamically select between different

implementations of one function (provided through the plugins). Thus it is

possible to use different accelerators on different problem sizes. Research

around the liftracc project has shown that you can get certain speedup from

such dynamic selection.

In this repository, as an example, the framework is used to build an

accelerated version of the blas (basic linear algebra subprogramms) interface.

A function collection of mathematical vector an matrix functions.

For further information on how to install, use and extend the framework have a

look at 'liftracc/library/documentation/html/index.html' after cloning.
