Linear Algebra PACKage
Branch: CURRENT,
Version: 3.6.1,
Package name: lapack3.6.1,
Maintainer: adamLAPACK is a highly portable Fortran 77 library which provides routines
for solving systems of simultaneous linear equations, leastsquares
solutions of linear systems of equations, eigenvalue problems, and
singular value problems. The associated matrix factorizations (LU,
Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are
related computations such as reordering of the Schur factorizations
and estimating condition numbers. Dense and banded matrices are
handled, but not general sparse matrices. In all areas, similar
functionality is provided for real and complex matrices, in both
single and double precision.

Log message:
Updated lapack to 3.6.1.
LAPACK 3.6.1: Whatâ€™s new
[Mark Gates, UTK] blocked backtransformation for the nonsymmetric eigenvalue \
problem
It blocks NB gemv calls into one gemm call inside trevc. To do
that, it needs a new routine, trevc3, because unfortunately the
lwork was not passed into trevc. Attached is the performance speedup
for dgeev. It gives a nice 1.5x speedup for N=20000, and that
appears to still be increasing with N. This is not the improvements
that Greg Henry recently provided for doing the triangular solves
as BLAS3 instead of BLAS1. That will take a while to process,
but we expect another, even larger increase in performance when
those changes are applied. This also does not include doing multiple
(BLAS1) triangular solves in parallel, which is available in MAGMA,
since that requires OpenMP or pthreads.

Log message:
Changes 3.5.0:
* added Symmetric/Hermitian LDLT factorization routines with rook pivoting algorithm
* 2by1 CSD to be used for tall and skinny matrix with orthonormal columns (in \
LAPCK 3.4.0, we already integrated CSD of a full square orthogonal matrix)
* New stopping criteria for balancing.
