SuiteSparse

Changes to the cmake build system.

Allow a specific BLAS library to be selected.

Changes to build system. METIS now integrated into the CHOLMOD library with all functions renamed so there can be no conflict with any non-modified METIS package. Added Fortran functions to AMD library

Fixes the build process when METIS is not compiled for use in SuiteSparse. Adds more instructions in README.

Revisions to cmake build system.

v6.0.0-beta3: adding NSTATIC option to disable the build of static libraries, and adding the installation of the SuiiteSparse_config/cmake_modules in /usr/local/lib/cmake/SuiteSparse (where /usr/local is CMAKE_INSTALL_PREFIX, in general).

For most packages, NSTATIC defaults to false (so static libraries are built). For GraphBLAS, the compilation takes a long time so the default is true (do not build the static libgraphblas.a). For Mongoose, the option is always false and ignored if set to true, since the static library is needed by the mongoose program.

Revised CMake / Makefile install rules. For the Makefiles:

• make: installs in /usr/local (or whatever CMAKE_INSTALL_PREFIX says). This is the default. Normally would require "sudo make install"
• make local: installs in SuiteSparse/lib, ./include, ./bin (ignoring CMAKE_INSTALL_PREFIX)
• make global: same as "make", but can be done after "make local" to reset what "make install" does
• make both: installs in both places

These are handled by CMake options: -DGLOBAL_INSTALL=(true or false, 0 or 1), and -DLOCAL_INSTALL=(ditto). By default, GLOBAL_INSTALL is true (like "make global", install in CMAKE_INSTALL_PREFIX) and LOCAL_INSTALL (install in SuiteSparse/lib, SuiteSparse/include) is false.

Nov 4, 2022: SuiteSparse 6.0.0 (beta1 release)

* major update: using CMake build system for all packages
* CMake Find*: all packages now have a Find*.cmake.  See
    SuiteSparse_config/cmake_modules.
* integers: int (32-bit) and SuiteSparse_long (nominally 64-bit) replaced
    with int32_t and int64_t.  The SuiteSparse_long #define has been
    deprecated and removed.  Replace its use with int64_t in any code that
    uses SuiteSparse v6.0.0 or later.  This is unlikely to change any
    use of any SuiteSparse package, but since it's possible that
    SuiteSparse_long was 32-bits on some platforms, the SO_VERSION of
    all packages has been increased by one.
* UMFPACK: new options to support ParU.  Single umfpack.h include file.
* CHOLMOD: Single cholmod.h include file.
* SuiteSparse/metis-5.1.0: renamed SuiteSparse_metis, to avoid confusion
    with the unmodified metis-5.1.0.  The compiled library is named
    libsuitesparse_metis.so.  The unmodified libmetis.so cannot be used
    with SuiteSparse.
* SPDX License Identifier: added to each file. No change in license.
* BLAS/LAPACK interface: now supports any Fortran BLAS/LAPACK, with
    either 32-bit (default) or 64-bit integers.
* SPEX: replaces SLIP_LU

Includes GraphBLAS v7.2.0.

* GraphBLAS v7.2.0:  see GraphBLAS/Doc/ChangeLog for details.
    * performance:  more compact serialization (ZSTD added, now the
        default compression method).
    * MATLAB interface: faster linear indexing, reshape, bandwidth,
        istril, istriu, isbanded, isdiag.  C(I,J)=A can now grow the
        size of C.
    * features: reshape methods, cube root operator, isStoredElement
    * bugs: a minor bug; user-defined types were incorrectly limited to
        128 bytes in size in v7.0.3.

GraphBLAS v7.0.3

Added GraphBLAS v6.2.5, plus minor updates to build system.

May 17, 2021, SuiteSparse 5.10.1

* CUDA: remove sm_30 from SuiteSparse_config.mk
* GraphBLAS v5.0.5: minor bug fix
* minor changes to Makefiles

SuiteSparse v5.10.0 with GraphBLAS v5.0.4

GraphBLAS upgraded from v3.3 to v4.0.3 with many new features, and increased performance. Betweeness Centrality about 2x faster, and now faster than the GAP benchmark for larger matrices. BFS about 5x faster. For the very latest versions of GraphBLAS, see https://github.com/DrTimothyAldenDavis/GraphBLAS where stable releases are more frequent. Those updates are added to this SuiteSparse meta-package on a slower release cycle.

July 14, 2020, SuiteSparse 5.8.1

* SLIP_LU v1.0.2: resolved issue #51
* GraphBLAS v3.3.3: bug fix (GraphBLAS issue #13)

SuiteSparse 5.8.0, July 3, 2020:

* SLIP_LU v1.0.1 added: for solving Ax=b exactly.  Requires
    the GNU GMP and MPRF libraries.
* GraphBLAS v3.3.1: see the GraphBLAS/Doc/Changlog
* replaced UFget with ssget: affects nearly all packages:
    UMFPACK, KLU, CHOLMOD, CXSparse/CSparse, etc,
    but their version numbers are left unchanged since it affects
    the MATLAB tests only, not the compiled libraries.
* ssget v2.2.0: better URL redirects
* updates to SuiteSparse build system

June 30, 2020, SuiteSparse 5.8.0

* GraphBLAS v3.3.1: see the GraphBLAS/Doc/Changlog
* replaced UFget with ssget

GraphBLAS v3.2.2: port to Windows.

Feb 20, 2020, SuiteSparse 5.7.1

* SuiteSparse_config: update version number
* Makefile: fixed install issue with README.txt

Feb 20, 2020, SuiteSparse 5.7.0

* GraphBLAS 3.2.0: better performance, new ANY and PAIR operators,

* added: CONTRIBUTIING.md, CODE_OF_CONDUCT.md, README.md.
