About the BLAS and LAPACK libraries

NOTE: Use of the Intel MKL BLAS is strongly recommended. In a 2019 test, OpenBLAS caused result in severe performance degradation. The reason for this is being investigated, and this may be resolved in the near future.

To select your BLAS/LAPACK, see the instructions in SuiteSparseBLAS.cmake in

SuiteSparse_config/cmake_modules
. If
SuiteSparse_config
finds a BLAS with 64-bit integers (such as the Intel MKL ilp64 BLAS), it configures
SuiteSparse_config.h
with the
SUITESPARSE_BLAS_INT
defined as
int64_t
. Otherwise, if a 32-bit BLAS is found, this type is defined as
int32_t
. If later on, UMFPACK, CHOLMOD, or SPQR are compiled and linked with a BLAS that has a different integer size, you must override the definition with -DBLAS64 (to assert the use of 64-bit integers in the BLAS) or -DBLAS32, (to assert the use of 32-bit integers in the BLAS).

When distributed in a binary form (such as a Debian, Ubuntu, Spack, or Brew package), SuiteSparse should probably be compiled to expect a 32-bit BLAS, since this is the most common case. The default is to use a 32-bit BLAS, but this can be changed in SuiteSparseBLAS.cmake or by compiling with

-DALLOW_64BIT_BLAS=1
.

By default, SuiteSparse hunts for a suitable BLAS library. To enforce a particular BLAS library use either:

CMAKE_OPTIONS="-DBLA_VENDOR=OpenBLAS" make cd Package ; cmake -DBLA_VENDOR=OpenBLAS .. make

To use the default (hunt for a BLAS), do not set

BLA_VENDOR
, or set it to ANY. In this case, if
ALLOW_64BIT_BLAS
is set, preference is given to a 64-bit BLAS, but a 32-bit BLAS library will be used if no 64-bit library is found.

When selecting a particular BLAS library, the

ALLOW_64BIT_BLAS
setting is strictly followed. If set to true, only a 64-bit BLAS library will be used. If false (the default), only a 32-bit BLAS library will be used. If no such BLAS is found, the build will fail.

Some codes optionally use METIS 5.1.0. This package is located in SuiteSparse in the

CHOLMOD/SuiteSparse_metis
directory. Its use is optional. To compile CHOLMOD without it, use the CMAKE_OPTIONS="-DNPARTITION=1" setting. The use of METIS can improve ordering quality for some matrices, particularly large 3D discretizations. METIS has been slightly modified for use in SuiteSparse; see the
CHOLMOD/SuiteSparse_metis/README.txt
file for details.

Refer to each package for license, copyright, and author information. All codes are authored or co-authored by Timothy A. Davis (email: davis@tamu.edu), except for METIS (by George Karypis), GraphBLAS/cpu_features (by Google), GraphBLAS/lz4 and zstd (by Yann Collet, now at Facebook), and GraphBLAS/CUDA/jitify.hpp (by NVIDIA). Parts of GraphBLAS/CUDA are Copyright (c) by NVIDIA. Please refer to each of these licenses.

Licenses for each package are located in the following files, all in PACKAGENAME/Doc/License.txt, and these files are also concatenated into the top-level LICENSE.txt file.


QUICK START FOR MATLAB USERS (Linux or Mac):

Uncompress the SuiteSparse.zip or SuiteSparse.tar.gz archive file (they contain the same thing). Suppose you place SuiteSparse in the /home/me/SuiteSparse folder.

Add the SuiteSparse/lib folder to your run-time library path. On Linux, add this to your ~/.bashrc script, assuming /home/me/SuiteSparse is the location of your copy of SuiteSparse:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/SuiteSparse/lib export LD_LIBRARY_PATH

For the Mac, use this instead, in your ~/.zshrc script, assuming you place SuiteSparse in /Users/me/SuiteSparse:

DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Users/me/SuiteSparse/lib export DYLD_LIBRARY_PATH

Compile all of SuiteSparse with "make local".

Next, compile the GraphBLAS MATLAB library. In the system shell while in the SuiteSparse folder, type "make gbmatlab" if you want to install it system-wide with "make install", or "make gblocal" if you want to use the library in your own SuiteSparse/lib.

Then in the MATLAB Command Window, cd to the SuiteSparse directory and type

SuiteSparse_install
. All packages will be compiled, and several demos will be run. To run a (long!) exhaustive test, do
SuiteSparse_test
.

Save your MATLAB path for future sessions with the MATLAB pathtool or savepath commands. If those methods fail because you don't have system-wide permission, add the new paths to your startup.m file, normally in Documents/MATLAB/startup.m. You can also use the

SuiteSparse_paths
m-file to set all your paths at the start of each MATLAB session.


QUICK START FOR THE C/C++ LIBRARIES:

For Linux and Mac: type the following in this directory (requires system priviledge to do the

sudo make install
):

make sudo make install

All libraries will be created and copied into SuiteSparse/lib and into /usr/local/lib. All include files need by the applications that use SuiteSparse are copied into SuiteSparse/include and into /usr/local/include.

For Windows, import each

*/CMakeLists.txt
file into MS Visual Studio. A single top-level CMake script is being considered as a feature in the future. Be sure to specify the build type as Release; for example, to build
SuiteSparse_config
on Windows in the command window:

cd SuiteSparse_config/build cmake .. cmke --build . --config Release

Be sure to first install all required libraries: BLAS and LAPACK for UMFPACK, CHOLMOD, and SPQR, and GMP and MPFR for SPEX. Be sure to use the latest libraries; SPEX requires MPFR 4.0.2 and GMP 6.1.2 (these version numbers do NOT correspond to the X.Y.Z suffix of libgmp.so.X.Y.Z and libmpfr.so.X.Y.Z; see the SPEX user guide for details).

To compile the libraries and install them only in SuiteSparse/lib (not /usr/local/lib), do this instead in the top-level of SuiteSparse:

make local

If you add /home/me/SuiteSparse/lib to your library search path (

LD_LIBRARY_PATH
in Linux), you can do the following (for example):

S = /home/me/SuiteSparse cc myprogram.c -I$(S)/include -lumfpack -lamd -lcholmod -lsuitesparseconfig -lm

To change the C and C++ compilers, and to compile in parallel use:

CC=gcc CX=g++ JOBS=32 make

for example, which changes the compiler to gcc and g++, and runs make with 'make -j32', in parallel with 32 jobs.

This will work on Linux/Unix and the Mac. It should automatically detect if you have the Intel compilers or not, and whether or not you have CUDA.

NOTE: Use of the Intel MKL BLAS is strongly recommended. The OpenBLAS can (rarely) result in severe performance degradation, in CHOLMOD in particular. The reason for this is still under investigation and might already be resolved in the current version of OpenBLAS. See

SuiteSparse_config/cmake_modules/SuiteSparsePolicy.cmake
to select your BLAS.

You may also need to add SuiteSparse/lib to your path. If your copy of SuiteSparse is in /home/me/SuiteSparse, for example, then add this to your ~/.bashrc file:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/SuiteSparse/lib export LD_LIBRARY_PATH

For the Mac, use this instead:

DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/home/me/SuiteSparse/lib export DYLD_LIBRARY_PATH

Python and Rust interfaces

See scikit-sparse and scikit-umfpack for the Python interface via SciPy:

https://github.com/scikit-sparse/scikit-sparse

https://github.com/scikit-umfpack/scikit-umfpack

See russell for a Rust interface:

https://github.com/cpmech/russell


Compilation options

You can set specific options for CMake with the command (for example):

CMAKE_OPTIONS="-DNPARTITION=1 -DNSTATIC=1 -DCMAKE_BUILD_TYPE=Debug" make

That command will compile all of SuiteSparse except for CHOLMOD/Partition Module. Debug mode will be used. The static libraries will not be built (NSTATIC is true).

CMAKE_BUILD_TYPE: Default: "Release", use "Debug" for debugging. ENABLE_CUDA: if set to true, CUDA is enabled for the project. Default: true for CHOLMOD and SPQR; false otherwise LOCAL_INSTALL: if true, "cmake --install" will install into SuiteSparse/lib and SuiteSparse/include. if false, "cmake --install" will install into the default prefix (or the one configured with CMAKE_INSTALL_PREFIX). Default: false NSTATIC: if true, static libraries are not built. Default: false, except for GraphBLAS, which takes a long time to compile so the default for GraphBLAS is true. For Mongoose, the NSTATIC setting is treated as if it always false, since the mongoose program is built with the static library. SUITESPARSE_CUDA_ARCHITECTURES: a string, such as "all" or "35;50;75;80" that lists the CUDA architectures to use when compiling CUDA kernels with nvcc. The "all" option requires cmake 3.23 or later. Default: "52;75;80". BLA_VENDOR a string. Leave unset, or use "ANY" to select any BLAS library (the default). Or set to the name of a BLA_VENDOR defined by FindBLAS.cmake. See: https://cmake.org/cmake/help/latest/module/FindBLAS.html#blas-lapack-vendors ALLOW_64BIT_BLAS if true: look for a 64-bit BLAS. If false: 32-bit only. Default: false. NOPENMP if true: OpenMP is not used. Default: false. UMFPACK, CHOLMOD, SPQR, and GraphBLAS will be slow. Note that BLAS and LAPACK may still use OpenMP internally; if you wish to disable OpenMP in an entire application, select a single-threaded BLAS/LAPACK. WARNING: GraphBLAS may not be thread-safe if built without OpenMP (see the User Guide for details). DEMO if true: build the demo programs for each package. Default: false.

Additional options are available within specific packages:

NCHOLMOD if true, UMFPACK and KLU do not use CHOLMOD for additional (optional) ordering options

CHOLMOD is composed of a set of Modules that can be independently selected; all options default to false:

NGL if true: do not build any GPL-licensed module (MatrixOps, Modify, Supernodal, and GPU modules) NCHECK if true: do not build the Check module. NMATRIXOPS if true: do not build the MatrixOps module. NCHOLESKY if true: do not build the Cholesky module. This also disables the Supernodal and Modify modules. NMODIFY if true: do not build the Modify module. NCAMD if true: do not link against CAMD and CCOLAMD. This also disables the Partition module. NPARTITION if true: do not build the Partition module. NSUPERNODAL if true: do not build the Supernodal module.
