Details:
- Updated herk_front() and her2k_front() to explicitly set the imaginary
components of the diagonal entries of C to zero after the computation
is complete. This is needed in case downstream applications read the
full diagonal entries (i.e., including imaginary part), which could, in
the absence of this modification, accumulate numerical error from
subsequent rank-k/rank-2k updates.
- Updated BLAS compatibility wrappers for herk and her2k to return early
if:
n == 0 || ( ( alpha == 0 || k == 0 ) && beta == 1 )
This also results in the imaginary components of diagonal entries NOT
being set to zero (see above), which is consistent with BLAS.
- Updated mkherm to use setid instead of an inlined loop over the
diagonal.
BLIS framework
README
---
Thank you for deciding to try out the BLIS framework!
BLIS is a portable framework for instantiating BLAS-like libraries. The
framework was designed to isolate essential kernels of computation that,
when optimized, immediately enable optimized implementations of most of
its commonly used and computationally intensive operations.
BLIS has many features. For more detailed information about the project,
please check the BLIS homepage:
http://code.google.com/p/blis/
You can keep in touch with developers and other users of the project by
joining one or more of the following mailing lists:
o blis-announce - http://groups.google.com/group/blis-announce
Used only for announcements and other important messages regarding
BLIS.
o blis-discuss - http://groups.google.com/group/blis-discuss
Please join and post to this mailing list if you have general questions
or feedback regarding BLIS. Application developers (end users) should
probably post here.
o blis-devel - http://groups.google.com/group/blis-devel
Please join and post to this mailing list if you are a BLIS developer
(i.e., you are trying to use BLIS to create libraries, you want to
write kernels for the framework, or you are trying to modify or extend
the framework itself).
Also, please read the LICENSE file for information on copying and
distributing this software.
For a step-by-step guide on configuring, compiling, and installing BLIS,
please read the INSTALL file. Also, please check the BLIS website's wiki
page for other useful how-to guides.
Thanks again for your interest in BLIS!
