Details:
- Made substantial changes throughout the framework to decouple the leading
dimension (row or column stride) used within each packed micro-panel from
the corresponding register blocksize. It appears advantageous on some
systems to use, for example, packed micro-panels of A where the column
stride is greater than MR (whereas previously it was always equal to MR).
- Changes include:
- Added BLIS_EXTEND_[MNK]R_? macros, which specify how much extra padding
to use when packing micro-panels of A and B.
- Adjusted all packing routines and macro-kernels to use PACKMR and PACKNR
where appropriate, instead of MR and NR.
- Added pd field (panel dimension) to obj_t.
- New interface to bli_packm_cntl_obj_create().
- Renamed bli_obj_packed_length()/_width() macros to
bli_obj_padded_length()/_width().
- Removed local #defines for cache/register blocksizes in level-3 *_cntl.c.
- Print out new cache and register blocksize extensions in test suite.
- Also added new BLIS_EXTEND_[MNK]C_? macros for future use in using a larger
blocksize for edge cases, which can improve performance at the margins.

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!
