Details: - Implemented algorithmic optimizations for trmm and trsm whereby the right side case is now handled explicitly, rather than induced indirectly by transposing and swapping strides on operands. This allows us to walk through the output matrix with favorable access patterns no matter how it is stored, for all parameter combinations. - Renamed trmm and trsm blocked variants so that there is no longer a lower/upper distinction. Instead, we simply label the variants by which dimension is partitioned and whether the variant marches forwards or backwards through the corresponding partitioned operands. - Added support for row-stored packing of lower and upper triangular matrices (as provided by bli_packm_blk_var3.c). - Fixed a performance bug in bli_determine_blocksize_b() whereby the cache blocksize extensions (if non-zero) were not being used to appropriately size the first iteration (ie: the bottom/right edge case). - Updated comments in bli_kernel.h to indicate that both MC and NC must be whole multiples of MR AND NR. This is needed for the case of trsm_r where, in order to reuse existing left-side gemmtrsm fused micro-kernels, the packing of A (left-hand operand) and B (right-hand operand) is done with NR and MR, respectively (instead of MR and NR).
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!
