Details:
- Updated External packages section in anticipation of introducing BLIS
into Debian package universe. Thanks to M. Zhou for sponsoring BLIS in
Debian.
Details:
- Implemented support for gemm where A, B, and C may have different
storage datatypes, as well as a computational precision (and implied
computation domain) that may be different from the storage precision
of either A or B. This results in 128 different combinations, all
which are implemented within this commit. (For now, the mixed-datatype
functionality is only supported via the object API.) If desired, the
mixed-datatype support may be disabled at configure-time.
- Added a memory-intensive optimization to certain mixed-datatype cases
that requires a single m-by-n matrix be allocated (temporarily) per
call to gemm. This optimization aims to avoid the overhead involved in
repeatedly updating C with general stride, or updating C after a
typecast from the computation precision. This memory optimization may
be disabled at configure-time (provided that the mixed-datatype
support is enabled in the first place).
- Added support for testing mixed-datatype combinations to testsuite.
The user may test gemm with mixed domains, precisions, both, or
neither.
- Added a standalone test driver directory for building and running
mixed-datatype performance experiments.
- Defined a new variation of castm, castnzm, which operates like castm
except that imaginary values are not touched when casting a real
operand to a complex operand. (By contrast, in these situations castm
sets the imaginary components of the destination matrix to zero.)
- Defined bli_obj_imag_is_zero() and substituted calls in lieu of all
usages of bli_obj_imag_equals() that tested against BLIS_ZERO, and
also simplified the implementation of bli_obj_imag_equals().
- Fixed bad behavior from bli_obj_is_real() and bli_obj_is_complex()
when given BLIS_CONSTANT objects.
- Disabled dt_on_output field in auxinfo_t structure as well as all
accessor functions. Also commented out all usage of accessor
functions within macrokernels. (Typecasting in the microkernel is
still feasible, though probably unrealistic for now given the
additional complexity required.)
- Use void function pointer type (instead of void*) for storing function
pointers in bli_l0_fpa.c.
- Added documentation for using gemm with mixed datatypes in
docs/MixedDatatypes.md and example code in examples/oapi/11gemm_md.c.
- Defined level-1d operation xpbyd and level-1m operation xpbym.
- Added xpbym test module to testsuite.
- Updated frame/include/bli_x86_asm_macros.h with additional macros
(courtsey of Devin Matthews).
Details:
- Replaced much of "Getting Started" section with a shortened version of
the bullet list of documentation currently shown in the github wiki
page. Thanks to Devangi Parikh for her feedback in this change.
Details:
- Rewrote bli_winsys.c to define bli_setenv() and bli_sleep()
unconditionally, but differently for Windows and non-Windows, but
then disabled the definition of bli_setenv() entirely since BLIS
no longer needs to set environment variables. Updated bli_winsys.h
accordingly, and call bli_sleep() from within testsuite instead of
sleep() directly.
- Use
#if !defined(_POSIX_BARRIERS) || (_POSIX_BARRIERS != 200809L)
instead of
#if !defined(_POSIX_BARRIERS) || (_POSIX_BARRIERS < 0)
when guarding against local definition of pthread barrier in
testsuite. (The description for unistd.h implies that _POSIX_BARRIERS
should always be set to 200809L when barriers are supported, though I
won't be surprised if we encounter a case in the future where it is
set to something else such as 1 while still supported.)
- Removed old _VERS_CONF_INST definitions and installation rules in
top-level Makefile. These are no longer needed because we no longer
output libraries with the version and configuration name as
substrings.
- Comment/whitespace updates in Makefile, config.mk.in, common.mk,
configure, bli_extern_defs.h, and test_libblis.h.
- Added mention of 1m to README.md and other trivial tweaks.
Details:
- Added links, and sandbox language to README.md.
- Adjusted some comments in high-level level-3 object functions to make
clear what bli_thread_init_rntm() does.
Details:
- Updated the typed and object APIs to include language on the rntm_t
parameters in the expert interfaces.
- Updated README to include link to object API.
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:
- Created a separate section of README.md for external packages, with
one bullet each for Dave Love's rpms and Nico Schlömer's Ubuntu apt
packages. Thanks to Dave and Nico for their contributions.
Details:
- Added bli_setgetijm.c, which defines bli_setijm(), bli_getijm(), and
related functions that can be used to read and write individual
elements of an obj_t.
- Defined a new function, bli_obj_create_conf_to(), in bli_obj.c that will
create a new object with dimensions conformal to an existing object.
Transposition and conjugation states on the existing object are ignored,
as are structure and uplo fields.
- Defined a new function, bli_datatype_string(), in bli_obj.c that returns
a char* to a string representation of the name of each num_t datatype.
For example, BLIS_DOUBLE is "double" and BLIS_DCOMPLEX is "dcomplex".
BLIS_INT is included (as "int"), but BLIS_CONSTANT is not, and thus is
not a valid input argument to bli_datatype_string().
- Added calls to bli_init_once() to various functions in bli_obj.c, the
most important of which was bli_obj_create_without_buffer().
- Removed unintended/extra newline from the end of printv output.
- Whitespace changes to
- frame/base/bli_machval.c
- frame/base/bli_machval.h
- frame/0/copysc/bli_copysc.c
- Trivial changes to README.md and common.mk.
Details:
- Fixed typos in README.md.
- Fixed column heading alignment for testsuite when matlab output is
enabled.
- Minor updates to test/3m4m/runme.sh and test/3m4m/Makefile.
Details:
- Replaced the old (and short) README file with a much more comprehensive
version written in github-flavored markdown. The new file is based on
content taken from the old Google Code homepage.
