The FASP++ is a C++ package designed for developing parallel iterative solvers and preconditioners for PDEs and systems of PDEs. The main components of the package are standard Krylov methods, algebraic multigrid methods, geometric multigrid methods, Schwarz methods, incomplete factorization methods, etc.

Install

There is a top level cmake for configuration and building of the FASP++ library and the test programs suite. You can use a cmake-style approach to compile the package; see https://cmake.org on how to use cmake for your own operating system. The typical command for compiling FASP++ is:

Config the environment for building with cmake:

  > mkdir Build; cd Build; cmake ..

After succesfully configing, just make the library as well as examples:

  > make  # to compile the FASP++ lib only; do not install

To make the library and install it, run:

  > make install  # to compile and install the FASP++ lib
