Unreleased Apha version -- Planned Public Release Milestone July 2018
I am currently refactoring the architecture of the API and library into two parts, the database and the query engine. This is to allow a more compact and flexible training/learning implementation and to use GPU or dedicated hardware implmentation for the metric space/topology or search egnine.
The main artefact of the project is the sdm runtime library which offers a high performance sparse distributed memory or semantic vector database targeted at a number of platforms.
The sdm library is currently written in C++ making extensive use of boost multiprocessing template library to provide memory management tools to allow the supporting data structures to be allocated from a memory mapped file, thus providing a database and RTL/API to act on it.
The application is high performance associative memory to further research and development of the capabilities of a general model of hyper-dimensional sparse space. This model has been extensively applied to and indeed was incubated in the domain of data/text mining particularly word level embeddings.
There is a c library under active development currently driven by the need for a foreign function interface for client languages. This currently supercedes the c++ library classes and may end up as the only API. Tho' is seems a shame to miss out on integrations using say boost python or other clever and efficient FFI bindings.
Requires cmake and (recommended) out of source build the build type Release is cruicial (unless a default Debug build is required) else performance will be an order of magnitude or more worse.
mkdir build;
cd build;
cmake -DCMAKE_BUILD_TYPE=Release ../src

make test && make installRequires doxygen
doxygenWill generate doc -- N.B. a C++ library is not currently built for standalone C++ clients as the entire library is more or less template based. This is unlikely to change unless this thing proves to be of use outside beyond scope of the research it now supports.
The c library is a very cut down shim of the full capability of the C++ implementation and serves the ad-hoc needs of the FFI.
