Details: - Fixed a bug in packm_cxk() whereby the packm ukernel was being chosen from ldp, which is always equal to PACKMR or PACKNR. The problem with this is that the pack ukernels were implicitly assuming that the panel dimension of the panel being packed was equal to ldp, which is not the case when the register blocksizes extensions are non-zero (ie: when PACKMR > MR or PACKNR > NR, whichever is applicable). This problem has been fixed by passing ldp into the pack ukernels, which now walk through the packed micro-panel region by incrementing by this value, rather than incrementing by the inherent panel dimension value assumed by each packm ukernel (e.g. 4 in the case of packm_ref_4xk). - Also fixed a very minor edge case inefficiency whereby pack ukernels smaller than the default were not being used in edge cases, and instead those situations were being handled by scal2m. This is related to the issue above, because the pack ukernel itself was being chosen based on ldp instead of the panel dimension.
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!
