Details:
- Removed BLIS_CONTIG_STRIDE_ALIGN_SIZE from bli_config.h of all
configurations. It was already going unused in packm_init() since the
recent 4m/3m commit. This setting was rarely, if ever, useful, and its
existence only posed a potential risk for 4m/3m-based implementations.
- Removed BLIS_CONTIG_STRIDE_ALIGN_SIZE usage from mem_pool_macro_defs.h.
- Updated comments regarding CONTIG_STRIDE_ALIGN_SIZE in template
micro-kernels.
Details:
- Standard names for reference kernels (levels-1v, -1f and 3) are now
macro constants. Examples:
BLIS_SAXPYV_KERNEL_REF
BLIS_DDOTXF_KERNEL_REF
BLIS_ZGEMM_UKERNEL_REF
- Developers no longer have to name all datatype instances of a kernel
with a common base name; [sdcz] datatype flavors of each kernel or
micro-kernel (level-1v, -1f, or 3) may now be named independently.
This means you can now, if you wish, encode the datatype-specific
register blocksizes in the name of the micro-kernel functions.
- Any datatype instances of any kernel (1v, 1f, or 3) that is left
undefined in bli_kernel.h will default to the corresponding reference
implementation. For example, if BLIS_DGEMM_UKERNEL is left undefined,
it will be defined to be BLIS_DGEMM_UKERNEL_REF.
- Developers no longer need to name level-1v/-1f kernels with multiple
datatype chars to match the number of types the kernel WOULD take in
a mixed type environment, as in bli_dddaxpyv_opt(). Now, one char is
sufficient, as in bli_daxpyv_opt().
- There is no longer a need to define an obj_t wrapper to go along with
your level-1v/-1f kernels. The framework now prvides a _kernel()
function which serves as the obj_t wrapper for whatever kernels are
specified (or defaulted to) via bli_kernel.h
- Developers no longer need to prototype their kernels, and thus no
longer need to include any prototyping headers from within
bli_kernel.h. The framework now generates kernel prototypes, with the
proper type signature, based on the kernel names defined (or defaulted
to) via bli_kernel.h.
- If the complex datatype x (of [cz]) implementation of the gemm micro-
kernel is left undefined by bli_kernel.h, but its same-precision real
domain equivalent IS defined, BLIS will use a 4m-based implementation
for the datatype x implementations of all level-3 operations, using
only the real gemm micro-kernel.
Details:
- Removed macro constant definitions related to incremental blocksizes
from all configurations' bli_kernel.h files. This change is minor and
is mostly a cleanup related to a previous commit.
Details:
- Modified build system (mostly configure and top-level Makefile) so that
a user can build a BLIS library outside of the top-level directory of
the source distribution.
- Added "test" target to Makefile so that the user can run "make test",
which will compile, link, and run the testsuite binary. This works even
if the build directory is externally located, thanks to the test suite
binary's new -g and -o command-line options. Also, when creating the
test suite via the top-level Makefile, the linking is against the
local archive, in lib/<configname>, rather than at <install_prefix>/lib.
- Modified testsuite/Makefile so that it links against the library built
locally, in ../lib/<configname>.
- Added "-lm" to LDFLAGS of most configurations' make_defs.mk.
- Various other cleanups to build system.
Details:
- Updated template micro-kernel implementations (located in
config/template/kernels), to adhere to the new auxinfo_t interface.
Meant to include this change in a0331fb1.
- Changed template configuration to use 64-bit integers (for both BLIS
and the BLAS compatibility layer).
Details:
- Changed top-level Makefile so that headers are installed to
$(INSTALL_PREFIX)/include/blis/. (Header directories are no longer
named by version/configuration and then symlinked.)
- Added uninstall targets, including uninstall-old to clean out old
library archives.
- Added GREP makefile definitions to all configurations' make_defs.mk.
Details:
- Added missing object wrappers to level-1f test suite modules. This was
only apparent if you were configuring with something other than the
reference configuration.
- Commented out object-wrappers in level-1f front-ends. These were not
working as intended the reference configuration was selected, because
most kernel sets, such as those in the template set, do not have object
wrappers.
- Whitespace changes to template micro-kernels.
- Comment changes to template level-1f kernel headers.
Details:
- Removed support for duplication from the gemmtrsm/trsm micro-kernels
and all framework code.
- Updated test suite modules according to above changes.
Details:
- Fixed a bug whereby BLIS assumed that the imaginary components of the
diagonal elements of Hermitian matrices were already zero. This property
is now enforced when the matrix is packed (bli_packm_blk_var2). Thanks
to Vladimir Sukharev for reporting this bug.
- Minor comment updates to template kernels.
Details:
- Fixed bugs in scalm and setm that resulted in segmentation faults when
beta is not the same type as the matrix operand. Thanks to Vladimir
Sukharev for reporting this bug.
- Changed axpym and scal2m front-ends in fashion similar to that of scalm
and setm; namely, the alpha scalar is copy-cast the type of the first
matrix operand.
- Changed the template and reference configurations' bli_config.h files
so that the number of memory allocator blocks of A and B are set based
on BLIS_MAX_NUM_THREADS.
- Comment updates to bli_obj.c and variable rename in bla_nrm2.c.
Details:
- Added test modules in test suite for level-1f kernels and level-3
micro-kernels. (Duplication in the micro-kernels, for now, is NOT
supported by these test modules.)
- Added section override switches to test suite's input.operations file.
- Added obj_t APIs for level-1f front-ends and their unblocked variants to
facilitate the level-1f test modules. Also added front-end for dupl
operation.
- Added obj_t-based check routines for level-1f operations, which are
called from the new front-ends mentioned above.
- Added query routines for axpyf, dotxf, and dotxaxpyf that return fusing
factors as a function of datatype, which is needed by their respective
test modules.
- Whitespace changes to bli_kernel.h of all existing configurations.
Details:
- Added a 'template' configuration, which contains stub implementations of the
level 1, 1f, and 3 kernels with one datatype implemented in C for each, with
lots of in-file comments and documentation.
- Modified some variable/parameter names for some 1/1f operations. (e.g.
renaming vector length parameter from m to n.)
- Moved level-1f fusing factors from axpyf, dotxf, and dotxaxpyf header files
to bli_kernel.h.
- Modifed test suite to print out fusing factors for axpyf, dotxf, and
dotxaxpyf, as well as the default fusing factor (which are all equal
in the reference and template implementations).
- Cleaned up some sloppiness in the level-1f unb_var1.c files whereby these
reference variants were implemented in terms of front-end routines rather
that directly in terms of the kernels. (For example, axpy2v was implemented
as two calls to axpyv rather than two calls to AXPYV_KERNEL.)
- Changed the interface to dotxf so that it matches that of axpyf, in that
A is assumed to be m x b_n in both cases, and for dotxf A is actually used
as A^T.
- Minor variable naming and comment changes to reference micro-kernels in
frame/3/gemm/ukernels and frame/3/trsm/ukernels.
