Package: suitesparse
Version: 3.1.0-3
There is a new upstream release of suitesparse available that includes a
new sparse QR factorization and solver that is significantly faster than
anything else available. I'd like to be able to include this in Octave
to improve the rank deficient, under- and over-determined solvers. Could
I request that this new version of suitesparse be packaged and in
particular that the new SPQR package be built. The upstream version
number of this new release is 3.2.0.
Attached a changed 13-UFconfig_UFconfig.mk.dpatch and a new
14-memcpy_needs_stringH.dpatch.
The latter should probably go upstream.
Reading the installation note of
http://www.cise.ufl.edu/research/sparse/SuiteSparse/
I believe upstream is already aware of this issue.
The former has two changes: upstream changed the line for BLAS =
and the new SPQR stuff needs -DNOPARTITION as well (I didn't check the
timing stuff, is it useful?).
-DNOPARTITION basically just removes METIS from the build, which is a
good idea as METIS although being a very good graph partitioner is not
GPL compatible. I'd say don't include the timing stuff, as it seems to
just be there for testing the code, and will slowup the factorization.
Cheers
