[gentoo-soc] [GSoC] Weekly Report : June 3-June 16 -- BLAS/LAPACK Runtime Switch

[Mo Zhou]

Hi list,

During the two weeks I finished the re-design of the
proposed BLAS/LAPACK runtime switching mechanism, and
actually implemented it. The initial design and
implementation was completely deprecated.

The details about the new ld.so.conf+eselect based
solution could be found from related discussions on
gentoo-dev. The code could be found here[1].

Specifically, the skeleton of the implementation
involves two customized eselect modules[2] and
the updated reference implementation[3]. They are
basically ready to merge but I still need to check
the help messages and manpages to assure correctness.

If no one is object to this solution, I'm going
to submit the first batch of PR on June 24~26.

According to the original schedule, the following
tasks should have been done before June 17:

1. update ebuild for reference blas/lapack and
   integrate the framework.
2. package BLIS and add it as a candidate

"1" was completed at the time of writing except
for a documentation check. "2" was finished and
it's actually working well. We are not lagging
behind the schedule despite the unexpected
redesign.

Best,
Mo.
