SuiteSparse_config, 2018, Timothy A. Davis, http://www.suitesparse.com
(formerly the UFconfig package)
This directory contains a default SuiteSparse_config.mk file. It tries to
detect your system (Linux, SunOS, or Mac), which compiler to use (icc or cc),
which BLAS and LAPACK library to use (OpenBLAS or MKL), and whether or not to
compile with CUDA.
For alternatives, see the comments in the SuiteSparse_config.mk file.
License: No licensing restrictions apply to this file or to the
SuiteSparse_config directory.
--------------------------------------------------------------------------------
SuiteSparse_config contains configuration settings for all many of the software
packages that I develop or co-author. Note that older versions of some of
these packages do not require SuiteSparse_config.
Package Description
------- -----------
AMD approximate minimum degree ordering
CAMD constrained AMD
COLAMD column approximate minimum degree ordering
CCOLAMD constrained approximate minimum degree ordering
UMFPACK sparse LU factorization, with the BLAS
CXSparse int/long/real/complex version of CSparse
CHOLMOD sparse Cholesky factorization, update/downdate
KLU sparse LU factorization, BLAS-free
BTF permutation to block triangular form
LDL concise sparse LDL'
LPDASA LP Dual Active Set Algorithm
RBio read/write files in Rutherford/Boeing format
SPQR sparse QR factorization (full name: SuiteSparseQR)
SuiteSparse_config is not required by these packages:
CSparse a Concise Sparse matrix package
MATLAB_Tools toolboxes for use in MATLAB
GraphBLAS graph algorithms in the language of linear algebra
In addition, the xerbla/ directory contains Fortan and C versions of the
BLAS/LAPACK xerbla routine, which is called when an invalid input is passed to
the BLAS or LAPACK. The xerbla provided here does not print any message, so
the entire Fortran I/O library does not need to be linked into a C application.
Most versions of the BLAS contain xerbla, but those from K. Goto do not. Use
this if you need too.
If you edit this directory (SuiteSparse_config.mk in particular) then you
must do "make purge ; make" in the parent directory to recompile all of
SuiteSparse. Otherwise, the changes will not necessarily be applied.
