SuiteSparse branches

* dev: the default branch, with recent updates of features to appear in
    the next stable release.  The intent is to keep this branch in
    fully working order at all times, but the features will not be
    finalized at any given time.
* stable: the most recent stable release.
* dev2: working branch.  All submitted PRs should made to this branch.
    This branch might not always be in working order.

For distro maintainers (Linux, homebrew, spack, R, Octave, Trilinos, ...):

Thanks for packaging SuiteSparse! Here are some suggestions:

* GraphBLAS takes a long time to compile because it creates many fast
    "FactoryKernels" at compile-time.  If you want to reduce the compile
    time and library size, enable the COMPACT mode, but keep the JIT
    enabled.  Then GraphBLAS will compile the kernels it needs at run-time,
    via its JIT.  Performance will be the same as the FactoryKernels once
    the JIT kernels are compiled.  User compiled kernels are placed in
    ~/.SuiteSparse, by default.  You do not need to distribute the source
    for GraphBLAS to enable the JIT: just libgraphblas.so and GraphBLAS.h
    is enough.

* GraphBLAS needs OpenMP!  It's fundamentally a parallel code so please
    distribute it with OpenMP enabled.  Performance will suffer
    otherwise.

* CUDA acceleration:  CHOLMOD and SPQR can benefit from their CUDA
    kernels.  If you do not have CUDA or do not want to include it in
    your distro, this version of SuiteSparse skips the building of
    the CHOLMOD_CUDA and SPQR_CUDA libraries, and does not link
    against the GPUQREngine and SuiteSparse_GPURuntime libraries.
    The latter can be excluded from your distro (the "make" command
    will build them, but they will be empty).

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.

Contents.m  a list of contents for 'help SuiteSparse' in MATLAB.

CSparse     a concise sparse matrix package, developed for my
            book, "Direct Methods for Sparse Linear Systems",
            published by SIAM.  Intended primarily for teaching.
            Note that the code is (c) Tim Davis, as stated in the book.
            For production, use CXSparse instead.  In particular, both
            CSparse and CXSparse have the same include filename: cs.h.
            This package is used for the built-in DMPERM in MATLAB.
            author: Tim Davis

CXSparse    CSparse Extended.  Includes support for complex matrices
            and both int or long integers.  Use this instead of CSparse
            for production use; it creates a libcsparse.so (or *dylib on
            the Mac) with the same name as CSparse.  It is a superset
            of CSparse.  Any code that links against CSparse should
            also be able to link against CXSparse instead.
            author: Tim Davis, David Bateman

include     'make install' places user-visible include files for each
            package here, after 'make local'

KLU         sparse LU factorization, primarily for circuit simulation.
            Requires AMD, COLAMD, and BTF.  Optionally uses CHOLMOD,
            CAMD, CCOLAMD, and METIS.
            authors: Tim Davis, Ekanathan Palamadai

LDL         a very concise LDL' factorization package
            author: Tim Davis

lib         'make install' places shared libraries for each package
            here, after 'make local'

Makefile    optional, to compile all of SuiteSparse

            make            compiles SuiteSparse libraries.
                            Subsequent "make install" will install
                            in just CMAKE_INSTALL_PATH (defaults to
                            /usr/local/lib on Linux or Mac).

            make local      compiles SuiteSparse.
                            Subsequent "make install will install only
                            in ./lib, ./include only.
                            Does not install in CMAKE_INSTALL_PATH.

            make global     compiles SuiteSparse libraries.
                            Subsequent "make install" will install in
                            just /usr/local/lib (or whatever your
                            CMAKE_INSTALL_PREFIX is).
                            Does not install in ./lib and ./include.

            make install    installs in the current directory
                            (./lib, ./include), and/or in
                            /usr/local/lib and /usr/local/include,
                            depending on whether "make", "make local",
                            or "make global" has been done.

            make uninstall  undoes 'make install'

            make distclean  removes all files not in distribution, including
                            ./bin, ./share, ./lib, and ./include.

            make purge      same as 'make distclean'

            make clean      removes all files not in distribution, but
                            keeps compiled libraries and demoes, ./lib,
                            ./share, and ./include.

            Each individual package also has each of the above 'make'
            targets.

            Things you don't need to do:
            make docs       creates user guides from LaTeX files
            make cov        runs statement coverage tests (Linux only)

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, zstd, and xxHash (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):

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 the default system-wide folder (/usr/local/lib on Linux). All include files need by the applications that use SuiteSparse are copied into /usr/local/include (on Linux).

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

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 (because of -DNPARTITION=1). Debug mode will be used (the build type). The static libraries will not be built (since -DNSTATIC=1 is set).

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

CMAKE_INSTALL_PREFIX:   defines the install location (default on Linux is
                    /usr/local).  For example, this command in the top
                    level SuiteSparse folder will set the install directory
                    to "/stuff", used by the subsequent "sudo make install":

                        CMAKE_OPTIONS="-DCMAKE_INSTALL_PREFIX=/stuff" make
                        sudo make install

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.
