Multithreaded sparse LU factorization library

Official package sites : http://crd.lbl.gov/~xiaoye/SuperLU/ ·

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions. This is the multi-threaded version (POSIX threads or OpenMP).

General

doc
Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
examples
Install examples, usually source code
int64
Build the 64 bits integer library
openmp
Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
static-libs
Build static versions of dynamic libraries as well
test
Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
threads
Add threads support for various packages. Usually pthreads

app-shells / tcsh : Enhanced version of the Berkeley C shell (csh)

virtual / blas : Virtual for FORTRAN 77 BLAS implementation

virtual / pkgconfig : Virtual for the pkg-config implementation

virtual / blas : Virtual for FORTRAN 77 BLAS implementation

*/*: [QA] Fix trivial cases of MissingTestRestrict
The result was achieved via the following pipeline: pkgcheck scan -c RestrictTestCheck -R FormatReporter \ --format '{category}/{package}/{package}-{version}.ebuild' | xargs -n32 grep -L RESTRICT | xargs -n32 sed -i -e '/^IUSE=.*test/aRESTRICT="!test? ( test )"' The resulting metadata was compared before and after the change. Few Go ebuilds had to be fixed manually due to implicit RESTRICT=strip added by the eclass. Two ebuilds have to be fixed because of multiline IUSE. Suggested-by: Robin H.
