KonstSolver is a high-performance vector and matrix library for .NET (C#, C++ and VB), thread based, 100% managed code. Parallel LU algorithm for solving dense system of linear equations Ax=b provides amazing speedup on multicore and multiprocessor computers. KonstSolver allows the following parallel matrix/vector operations: add, substract, multiply vector and/or matrix, divide by constant, etc. Many of modern PCs and servers have multicore or multiprocessor hardware available. But sequential algorithms cannot be run in parallel without using special techniques. It is necessary to separate a code to subtasks and run them on different threads. KonstSolver is easy to use, intuitive predicted library, you can use matrix/vector/constant operators +, -, *, / in standard way. Such algorithms are parallel and optimized for .NET platform. Amdahl's laws works. It means that vector and matrix operations can be parallelized with very high speedup. Even such low-granular tasks as LU decomposition for solving dense linear equations can be done in effective way. KonstSolver will make your software faster, relaible and precesious. The library is extensible and allows you to built your custom classes over existing infrastructure.
