Blaze-Iterative

This is a set of iterative linear system solvers intended for use with the Blaze library, a high-performance C++ linear algebra library (https://bitbucket.org/blaze-lib/). The API is currently based on a tag-dispatch system to choose a particular algorithm.

Currently implemented algorithms:

• Conjugate Gradient (CG)
• BiCGSTAB

Planned algorithms:

• Preconditioned CG
• Preconditioned BiCGSTAB
• (Preconditioned) BiCGSTAB(l)
• GMRES
• Arnoldi
• Lanczos

Potential algorithms (if sufficient interest):

• LSQR
• LSMR

Please open an issue to discuss/request features.

Installation

Installing BlazeIterative is done via the usual CMake procedure:

• create an out-of-tree build directory (highly recommended)
• run cmake
• build and install using your favorite build systems

An example of the process on a linux-like system might be (from the BlazeIterative root):

mkdir build && cd build
ccmake .. # This is where you set your install location, defaults to /usr/local on my machine
make && make install

The library headers will install to ${CMAKE_INSTALL_PREFIX}/include/BlazeIterative. The cmake files that allow you to find_package(BlazeIterative) are installed in ${CMAKE_INSTALL_PREFIX}/share/BlazeIterative/cmake. If CMAKE_INSTALL_PREFIX is on your CMAKE_PREFIX_PATH, then find_package(BlazeIterative) should work without any issues (tested with cmake 3.9).

Using BlazeIterative in your projects

BlazeIterative is developed using CMake, so it is easy to use in another CMake project. The installation process exports the target: "BlazeIterative::BlazeIterative", which should be linked against. This will take care of linking against Blaze, but you still must find the blaze package in your own project (if anyone knows how to solve the transitive dependency problem in cmake, please teach me!). This is a minimal example of a CMakeLists.txt for a project using BlazeIterative.
