Details:
- Added documentation to docs/BLISObjectAPI.md for a handful of
commonly-used obj_t accessor functions.
- Minor updates to docs/BLISTypedAPI.md.
Details:
- Created a 'studies' subdirectory within 'test' to be used to house
test drivers, makefiles, run scripts, matlab plot code, and related
files that have been customized for collecting performance data on
specific host machines or product lines. This new setup will help us
catalog, track, and share test driver materials over time, and in a
way that facilitates reproducibility.
- Created an 'skx' subdirectory within 'test/studies' to house various
level-3 test driver files used to measure performance on SkylakeX
nodes (specifically, those nodes used by TACC's stampede2 system).
Details:
- Deleted some lines from the API function signatures that did not
belong (and were only left over from the copy-paste of the typed API).
- Fixed some paragraph-in-bullet indentation.
Details:
- Added first draft of BLISObjectAPI.md. (Object management section is
still missing.)
- Small fixes to BLISTypedAPI.md found while writing BLISObjectAPI.md.
- In various .md files, changed ``` verbatim blocks to language
attributes (e.g. ```c for C code).
Details:
- Added missing pthreads library linking to example makefile in
docs/BuildSystem.md, as well as similar language to build requirements
at the beginning of the document. Thanks to Stefanos Mavros for
bringing this to our attention.
- Updated CREDITS file.
Details:
- Minor updates to BLISTypedAPI.md, mostly to bring terminology
up-to-date with the new "typed API" classification.
- Added contents section to KernelsHowTo.md.
Details:
- Added missing level-1v operations to BLISTypedAPI (e.g. axpbyv,
xpbyv).
- Updated broken linkes in KernelsHowTo.md based on misnamed anchors.
- Other minor changes.
Details:
- Fixed stale calls to dscalv() from the dotxf and dotxaxpyf penryn
kernels that were not updated during the basic/expert API separation
in e88aeda.
Details:
- Added language to README.md to bring the reader's attention to the
example code for the typed API (in addition to those for the object
API).
Details:
- Updated wiki links according to renamed/relocated files in 'docs'.
- Converted links to relative paths.
- Added link to docs/Multithreading.md.
Details:
- Within the documents in docs/*.md, reverted links to other local
documents to relative paths.
- Fixed some links/documents that did not yet have the '.md' suffix.
- Testing whether we can use relative links ('docs/BLISTypedAPI.md')
from within README.md.
Details:
- Updated most markdown links in the documents/wikis to use absolute
paths instead of the relative paths that were in use previously.
A few links were not updated, except for adding a ".md" to reflect
the documents' new names, in order to test whether relative
linking still works.
Details:
- Exported all github wikis to a new 'docs' directory.
- Renamed 'BLISAPIQuickReference' wiki to 'BLISTypedAPI' and removed
all cntx_t* arguments from the (now non-expert) APIs (with the
exception of the kernel APIs).
- Added section to BuildSystem documenting new ARG_MAX hack.
Details:
- Renamed various files that were previously named according to a
"with context" or "without context" convention. For example, the
following files in frame/3 were renamed:
frame/3/bli_l3_oapi_woc.c -> frame/3/bli_l3_oapi_ba.c
frame/3/bli_l3_oapi_wc.c -> frame/3/bli_l3_oapi_ex.c
frame/3/bli_l3_tapi_woc.c -> frame/3/bli_l3_tapi_ba.c
frame/3/bli_l3_tapi_wc.c -> frame/3/bli_l3_tapi_ex.c
Here, the "ba" is for "basic" and "ex" is for "expert". This new
naming scheme will make more sense especially if/when additional
expert parameters are added to the expert APIs (typed and object).
Details:
- Split existing typed APIs into two subsets of interfaces: one for use
with expert parameters, such as the cntx_t*, and one without. This
separation was already in place for the object APIs, and after this
commit the typed and object APIs will have similar expert and non-
expert APIs. The expert functions will be suffixed with "_ex" just as
is the case for expert interfaces in the object APIs.
- Updated internal invocations of typed APIs (functions such as
bli_?setm() and bli_?scalv()) throughout BLIS to reflect use of the
new explictly expert APIs.
- Updated example code in examples/tapi to reflect the existence (and
usage) of non-expert APIs.
- Bumped the major soname version number in 'so_version'. While code
compiled against a previous version/commit will likely still work
(since the old typed function symbol names still exist in the new API,
just with one less function argument) the semantics of the function
have changed if the cntx_t* parameter the application passes in is
non-NULL. For example, calling bli_daxpyv() with a non-NULL context
does not behave the same way now as it did before; before, the
context would be used in the computation, and now the context would
be ignored since the interace for that function no longer expects a
context argument.
* Upload artifacts built on appveyor (#228)
* Upload artifacts
* Fix install in appveyor
* Remove windows.h in bli_winsys.c (#229)
Looks like it is unneeded.
* Implemented ARG_MAX hack in configure, Makefile.
Details:
- Added support for --enable-arg-max-hack to configure, which will
change the behavior of make when building BLIS so that rather than
invoke the archiver/linker with all of the object files as command
line arguments, those object files are echoed to a temporary file
and then the archiver/linker is fed that temporary file via the @
notation. An example of this can be found in the GNU make docs at
https://www.gnu.org/software/make/manual/make.html#File-Function
- Thanks to Isuru Fernando for prompting this feature.
* Enable x86_64 and arg-max-hack on appveyor

Details:
- Added new example code to examples/tapi demonstrating how to use the
BLIS typed API. These code examples directly mirror the corresponding
example code files in examples/oapi. This setup provides a convenient
opportunity for newcomers to BLIS to compare and contrast the typed
and object APIs when they are used to perform the same tasks.
- Minor cleanups to examples/oapi.
Details:
- Implemented bli_obj_scalar_cast_to(), which will typecast the value in
the internal scalar of an obj_t to a specified datatype.
- Changed bli_obj_scalar_attach() so that the scalar value being attached
is first typecast to the storage datatype of the destination object
rather than the target datatype.
- Reformatted function type signatures in bli_obj_scalar.c as well as
prototypes in its corresponding header file.
Details:
- Fixed incorrect bit shifts in the following static functions:
bli_obj_set_target_domain()
bli_obj_set_target_prec()
bli_obj_set_exec_domain()
bli_obj_set_exec_prec()
- Fixed incorrect bitmask in bli_dt_proj_to_single_prec().
- Updated bli_obj_real_part() and bli_obj_imag_part() so that it updates
the target and exec datatypes (in addition to the storage datatypes).
Details:
- Added a new field to the auxinfo_t struct that can be used, in theory,
to request type conversion before the microkernel stores/accumulates
its microtile back to memory.
- Added the appropriate get/set static functions to bli_type_defs.h.
Details:
- This commit fixes several bugs in configure relating to selecting a C
compiler. By dumb luck, two of the two bugs sort of cancelled each
other out in most use cases, which manifested as the expected behavior.
Thanks to Mathieu Poumeyrol for bringing this issue to our attention,
and to Devin Matthews for suggesting the more portable way of
capturing both stdout and stderr and suggesting a return code check
instead of testing stdout/stderr.
- The first bug: As the values of the compiler search list are iterated
over, only stderr is captured when querying a compiler with --version
rather than both stdout and stderr.
- The second bug: After each query, a conditional attempted to test
whether the query resulted in anything being output. That conditional
erroneously was using "-z" instead of "-n" for non-emptiness. Thus,
most of the time, stderr was empty (because the --version info was
being output on stdout), and since it was empty, the -z conditional
(intended to execute only when a compiler was found to be responsive)
executed.
- A third bug was also fixed in the way that the merged stdout/stderr
output was tested for non-emptiness (moving the 'cat' invocation to
another line and testing the contents of a variable instead).
- The three bugs above have been fixed as part of a partial rewrite of
the select_cc() function in terms of a return code check, which
obviated the need to save the output of stdout and stderr.
- The fourth bug involved a misnamed variable in the right-hand side
of a statement intended to prepend CC to search_list when CC was
non-empty. This typically did not manifest as a bug since usually CC
(if it was set) was set to a value that was known to work.
Details:
- Added mention of the new support for preset CFLAGS, LDFLAGS to the
bottom of the text output by './configure --help'.
- Updated usage example to use 'haswell' instead of 'sandybridge'.
Details:
- Any preexisting values set to the CFLAGS environment variable (or the
CFLAGS variable if given on the command line) are saved by configure
for later inclusion (prepending, to be precise) along with the
compiler flags automatically determined by the BLIS build system.
LDFLAGS is treated in a similar manner.) Thanks to Dave Love for
requesting this feature in issue #223 and Mathieu Poumeyrol for his
support on this and a previous related issue.
- Comment updates to build/config.mk.in.
- Strip whitespace from return value of various cflags functions in
common.mk.
Details:
- Added definitions of static functions bli_dt_domain()/bli_dt_prec(),
which extract a dom_t domain or prec_t precision value, respectively,
from a num_t datatype.
- Changed the return types of bli_obj_domain() and bli_obj_prec() from
objbits_t to dom_t and prec_t. (Not sure why they were ever set to
return objbits_t.)
Details:
- Added static functions for projecting a datatype to single precision
or double precision, both for obj_t's storage datatypes and standalone
datatypes.
Details:
- Added two presently-disabled cpp blocks in bli_cntx_init_haswell.c to
easily allow one to switch to a set of column-preferential gemm
microkernels (in the haswell subconfiguration). The second column-
preferring block sets the the register blocksizes to their appropriate
values. However, cache blocksizes are left unchanged, and therefore are
likely suboptimal. This should be addressed later.
Details:
- Added functions to bli_obj_macro_defs.h to get and set the target
domain and target precision bits in the obj_t, and also added the
appropriate support in bli_type_defs.h.
