Details: - Fixed a bug that affects all level-2 and level-3 blocked variants. The bug only manifested, however, if the packing of operands (A and B in gemm, for example) spanned multiple nodes in the control tree. Until recently, the main consumers of packm were level-3 operations, all of which packed both input operands from blocked variant 1 (B outside of the loop, and A within the loop). This particular usage masked a flaw in the code whereby bli_obj_release_pack() would always release the underlying mem_t buffer (provided it was allocated), even if the buffer was not allocated in the current variant. This has been fixed by replacing all calls to bli_obj_release_pack() with calls to a new function, bli_packm_release(), which takes the same control tree node argument passed into the object's corresponding call to packm_init() or packv_init(). bli_packm_release() then proceeds to invoke bli_obj_release_pack() only if the control tree node indicates that packing was requested. Thanks to Devangi Parikh for identifying this bug.
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!
