[GSoC] fortnightly: blas/lapack enhancements

[Mo Zhou <lumin@debian.org>]

Hi team,

My gsoc project involves several tracks of works. And the following is
a summary about the current progress:
(The list is tracked at
 https://salsa.debian.org/lumin/gsoc2020-debian-blaslapack/-/blob/master/README.md
 and it will grow over time)

Threading-aware virtual blas (status: stopped)
----------------------------------------------

RFC https://lists.debian.org/debian-science/2020/05/msg00023.html

Bumping system default blas/lapack provider (status: stopped)
-------------------------------------------------------------

https://lists.debian.org/debian-science/2020/06/msg00022.html
Conclusion: different BLAS/LAPACK have slightly different behaviour.
Keeping the netlib blas/lapakc as the default provider is a preferrable choice,
lest some reverse dependencies fail to build due to test errors.

Deprecating libcblas
--------------------

https://lists.debian.org/debian-science/2020/05/msg00050.html
Status: already merged. lintian will report an INFO message when there is
ELF binary linked against libcblas.so.

Julia support
-------------

https://lists.debian.org/debian-science/2020/05/msg00032.html
Status: libopenblas64-julia is still waiting in the new queue.

libflame (a better LAPACK)
--------------------------

https://ftp-master.debian.org/new/libflame_5.2.0-1.html
Status: still in NEW.
