SpAMM, the Sparse Approximate Matrix Multiply.

Build Instructions

This library uses CMake. Simply run

cmake .
make

to build it. For extra convenience, we provide a shell script that configures and builds spammpack out-of-source in a directory called build.

./build.sh

will create a new directory build and compile the sources in that directory. The script honors the following environment variables, and passes them to the cmake command.

CMAKE_BUILD_TYPE
SPAMM_DEBUG_LEVEL
CMAKE_VERBOSE_MAKEFILE
CMAKE_C_COMPILER
CMAKE_Fortran_COMPILER

Building with full debugging

Configurating the library using

cmake -DCMAKE_BUILD_TYPE=Debug -DSPAMM_DEBUG_LEVEL=2 .

will set compiler flag defaults that include bounds checking (we currently support GNU and Intel compilers).

Building with a specific compiler

When cmake is run, it searches for a suitable Fortran compiler. If the one it finds is not the one you would like to use, you have to explicitly specify the compiler as

cmake -DCMAKE_Fortran_COMPILER=FCompiler

where the FCompiler can be the name of the compiler executable with or without an absolute path.

Emacs suggested settings

For emacs users we have a suggested set of settings we use. Have a look at emacs-settings.el. This file can simply be copy and pasted into an existing ~/.emacs configuration file.

Some other useful things to know

The ctags and etags targets generate tags files for vim and emacs, respectively. The tags file is written to the repository root directory.

make etags
