Details: - Fixed some bugs that only manifested in multithreaded instances of some (non-gemm) level-3 operations. The bugs were related to invalid allocation of "edge" cases to thread subpartitions. (Here, we define an "edge" case to be one where the dimension being partitioned for parallelism is not a whole multiple of whatever register blocksize is needed in that dimension.) In BLIS, we always require edge cases to be part of the bottom, right, or bottom-right subpartitions. (This is so that zero-padding only has to happen at the bottom, right, or bottom-right edges of micro-panels.) The previous implementations of bli_get_range() and _get_range_weighted() did not adhere to this implicit policy and thus produced bad ranges for some combinations of operation, parameter cases, problem sizes, and n-way parallelism. - As part of the above fix, the functions bli_get_range() and _get_range_weighted() have been renamed to use _l2r, _r2l, _t2b, and _b2t suffixes, similar to the partitioning functions. This is an easy way to make sure that the variants are calling the right version of each function. The function signatures have also been changed slightly. - Comment/whitespace updates. - Removed unnecessary '/' from macros in bli_obj_macro_defs.h.
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!
