Details:
- Updated frame/util/dupl/bli_dupl_unb_var1.c to utilize PACKNR and NR
explicitly so navigate b1 so that situations where PACKNR > NR are
supported.
- Moved the 4x2 and 4x4 reference micro-kernels in frame/3/gemm/ukernels and
frame/3/trsm/ukernels to kernels/c99/.
- Updated clarksville and flame configurations.
Details:
- Fixed a bug in reference implementation of dupl (bli_dupl_unb_var1.c),
which resulted in incorrect duplication.
- Updated old test drivers according to recently updated packm control tree
creation interface.
- Added 'restrict' to x86 gemm microkernel interface.
Details:
- Renamed abs, min, max, dmin, and dmax macros in bli_f2c.h so that they
would not conflict with anything defined by the user (or the language).
Thanks to Devin Matthews for suggesting this fix.
- Updated all instances of the above macros accordingly.
Details:
- Replaced scalar constant macro definitions in bli_const_defs.h with a single,
simplier macro in bli_obj_macro_defs.h.
- Updated invocations of old macros accordingly.
- Removed bli_const_defs.h.
Details:
- Implemented amax operation in BLIS.
- Activated BLAS2BLIS routine mapping for new amax BLIS implementation.
- Added integer support to [f]printv, [f]printm.
- Added integer support to level-0 copys macros.
- Updated printing of configuration information in test suite driver.
- Comment changes to _config.h files.
- Added comments to bla_dot.c to reminder reader what sdsdot()/dsdot() are
used for.
Details:
- Changed all filename and function prefixes from 'bl2' to 'bli'.
- Changed the "blis2.h" header filename to "blis.h" and changed all
corresponding #include statements accordingly.
- Fixed incorrect association for Fran in CREDITS file.
Details:
- Removed #include of "blis2.h" from various lower-level, operation-specific
header files throughout the framework. Given that these low-level headers
are included within #blis2.h in a very specific order, #include'ing blis2.h
within them directly is unnecessary.
Details:
- Changed name of set0 and set0_mxn macros to set0s and set0s_mxn,
respectively.
- Added code to the following operations that sets the output operand to
zero if the corresponding scalar is zero (rather than performing the
floating-point multiply, or in the case of setv, copying the value).
This will prevent nan's and inf's from creeping into results from
uninitialized memory.
- axpy
- dotxv
- scalv
- scal2v
- setv
- gemv
- ger
- hemv
- her
- her2
- gemm reference ukernels
Details:
- Added a highly configurable, unified test suite.
- Removed DUPB configuration constant from bl2_kernel.h and macro-kernel
header files. Now, instead, DUPB is computed as (NDUP != 1) within each
macro-kernel. This fixes a bug in trmm/trsm whereby bp was indexed into
incorrectly when DUPB was set to FALSE but the NDUP was still non-unit.
By encoding both pieces of information into one constant in _kernel.h,
it seems somewhat less likely others will encounter this bug in the
future.
- Added level-2 cache blocksizes to _kernel.h for reference configuration,
and defined blocksizes in _cntl.c files to these default values.
- Changed semantics of her2k and syr2k such that these operations no longer
expect the B matrix to already be conjugate-transposed (or just transposed
for syr2k). However, these semantics are preserved for the internal
mechanics of the implementations, including the internal back-end and all
blocked variants.
- Inserted checks for real-valued alpha and beta for herk/her2k and herk,
respectively.
- Relaxed general object structure constraints in _basic_check() for gemv, ger.
- Changed her front-end to NOT copy-cast to real projection; instead, this is
replaced by selecting either the real part or both parts within the unblocked
algorithm implementation, depending on the value of conjh.
- Added conjh to all _check routines for her so that the code knows when to
verify that alpha has an imaginary component equal to zero (for her, but
not syr).
- Changed control tree for her to forgo packing.
- Added unit diagonal support to fnormm.
- Redefined real versions of abval2s macros in terms of fabs(), fabsf().
- Redefined complex versions of sqrt2s macros using the actual "complex square
root" formula.
- Created new level-0 object-based routines, suffixed with "sc" (for "scalar").
- Defined new level-1v, -1d, and -1m versions of add and sub operations
(two-operand add and subtract).
- Added new scalar macros:
- getris: acquire real and imaginary components.
- setris: set real and imaginary components.
- addjs: addition with conjugated x.
- subjs: subtraction with conjugated x.
- Defined new utility operations:
- absumv: element-wise sum of absolute values for vector elements.
- absumm: element-wise sum of absolute values for matrix elements.
- mkherm: convert existing matrix to Hermitian.
- mksymm: convert existing matrix to symmetric.
- mktrim: convert existing matrix to triangular.
- Added various error checking routines.
- Added bl2_clock_min_diff(), which is used to more cleanly measure the
wall clock time of a code block.
- Added general stride support to bl2_obj_alloc_buffer().
- Added bl2_obj_init_scalar().
- Updated parameter mapping in bl2_param_map.c.
- Added support for queriable version string.
- Fixed a bug in the her2k macro-kernels (which currently are simply
implemented in terms of two invocations of herk) whereby beta was being
applied to both the first and second rank-k updates, rather than only
the first.
- Fixed a bug in trmm/trsm whereby transpose and right side cases were not
properly implemented due to erroneous assumptions regarding aliasing and
root objects.
- Fixed a bug in the upper triangular trsm macro-kernel in which the wrong
MR x NR block of B was being updated.
- Fixed a bug in the inverts macro in the double real case whereby the
value was typecast to float before inversion. This affected non-unit cases
of dtrsm.
- Fixed a bug in the reference kernels for gemmtrsm whereby the minus one
constant was being applied incorrectly.
- Fixed a bug in the overall treatment of non-unit alpha for trsm. The code
now mimics the rank-k strategy of gemm, whereby alpah is applied during
the first iteration of variant 3, with BLIS_ONE passed in instead for
subsequent iterations. This also required passing alpha into the macro-
kernels as well as the fused gemmtrsm micro-kernels.
- Fixed a bug in trsm_u_blk_var1 whereby the gemm macro-kernel was being
called for blocks strictly above the diagonal. While this sounds good in
theory, this cannot be done because gemm_ker_var2 expects row panels of
A to be packed from top to bottom, while for trsm_u, A is actually packed
from bottom to top due to the reverse (BR->TL) nature of the algorithm.
- Fixed a bug in packm_cxk() whereby panel packings with unit panel
dimensions were mishandled due to incorrect arguments to the copyv kernel.
Also changed the copyv kernel invocation to scal2v so that these edge
cases are properly handled when scaling is requested.
- Fixed a bug in packv_int() whereby an uninitialized object is passed in
instead of the source object.
- Fixed a bug whereby level-2 code could allocate memory dynamically via
bl2_malloc() and then attempt to free it via bl2_mm_release(). Also fixed
a potential future bug whereby a mem_t object that is actually no longer
"allocated" from the static pool is mistaken for being allocated due to
failure to NULLify the buffer when the block was most recently released.
- Fixed a bug in bl2_acquire_mpart_*() whreby the uplo field was mistakenly
toggled when the requested subpartition needed to be "reflected" due to it
residing in an unstored region.
Details:
- Added level-0 grabis macro operation to grab imaginary component of one
variable and copy it to the real component of another variable.
- Defined sumsqv operation, which computes the sum of the absolute squares
of the elements of a vector. This implementation is modeled after ?lassq
in netlib LAPACK.
- Defined fnormv and fnormm operations, which compute the Frobenius norm on
vectors and matrices, respectively. These operations are treated as one-
operand operations where the output norm value is the real projection of
the datatype of the input operand. Both operations are implemented in terms
of sumsqv.
Details:
- Fixed some inconsistent usage of n_iter_max and n_iter in the two
bl2_set_dims_incs_uplo_[12]m macros. The right thing ended up happening
despite the bug, which is why I had not discovered it until now.
