Details:
- In light of recent segfaulting issues when compiling on 32-bit systems,
I've changed the default typedef for gint_t and guint_t from int64_t and
uint64_t to int32_t and uint32_t, respectively.
- Disabled 64-bit integers in the blas2blis layer for the reference
configuration.
- Added type sizes of gint_t, guint_t, and the four floating-point datatypes
to introductory output of the testsuite.
Details:
- Changed the BLIS_HEAP_STRIDE_ALIGN_SIZE in the configurations from 16 to
BLIS_CACHE_LINE_SIZE (typically 64).
- Changed the use of nr in sizing of bd buffer to packnr in level-3 macro-
kernels.
- Reformulated gemm_ker_var2 to look more like the other level-3 macro-
kernels, in that the interior and edge-case handling is expressed once
inside the loops in the n and m dimensions, rather than the edge-case
handling being "unrolled" and expressed as distinct code regions. The
previous macro-kernel now lives in retired form in the subdirectory
other/bli_gemm_ker_var2.c.old.
- Updated experimental gemm_ker_var5 according to above change.
- Fixed bug in bli_her2k.c whereby incorrect transformations were being
applied to optimize the macro-kernel accesses pattern on C when C is
row-stored.
- Various updates inside of test/exec_sizes.
Details:
- Added support for C99 complex types to bli_type_defs.h and overloaded
complex arithmetic to the scalar-level macros in include/level0. This
includes a somewhat substantial reorganization and re-layering of much
of the existing machinery present in the level0 macros.
- Added new #define for BLIS_ENABLE_C99_COMPLEX to bli_config.h files,
commented-out by default, which optionally enables the use of built-in
C99 complex types and arithmetic.
- Minor changes to clarksville and reference configs' make_defs.mk files.
- Removed macro definitions from bli_param_macro_defs.h which was not being
used (bli_proj_dt_to_real_if_imag_eq0).
Details:
- Changed the way bli_type_defs.h defines integer types so that dim_t,
inc_t, doff_t, etc. are all defined in terms of gint_t (general signed
integer) or guint_t (general unsigned integer).
- Renamed Fortran types fchar and fint to f77_char and f77_int.
- Define f77_int as int64_t if a new configuration variable,
BLIS_ENABLE_BLIS2BLAS_INT64, is defined, and int32_t otherwise.
These types are defined in stdint.h, which is now included in blis.h.
- Renamed "complex" type in f2c files to "singlecomplex" and typedef'ed
in terms of scomplex.
- Renamed "char" type in f2c files to "character" and typedef'ed in terms
of char.
- Updated bla_amax() wrappers so that the return type is defined directly
as f77_int, rather than letting the prototype-generating macro decide
the type. This was the only use of GENTFUNC2I/GENTPROT2I-related macros,
so I removed them. Also, changed the body of the wrapper so that a
gint_t is passed into abmaxv, which is THEN typecast to an f77_int
before returning the value.
- Updated f2c code that accessed .r and .i fields of complex and
doublecomplex types so that they use .real and .imag instead (now that
we are using scomplex and dcomplex).
Details:
- Added new memory alignment constants:
BLIS_HEAP_STRIDE_ALIGN_SIZE (previously assumed to be same as SYSTEM_MEM)
BLIS_CONTIG_ADDR_ALIGN_SIZE (previously assumed to be same as PAGE_SIZE)
BLIS_STACK_BUF_ALIGN_SIZE (previously not enforced)
and renamed existing ones
BLIS_SYSTEM_MEM_ALIGN_SIZE -> BLIS_HEAP_ADDR_ALIGN_SIZE
BLIS_CONTIG_MEM_ALIGN_SIZE -> BLIS_CONTIG_STRIDE_ALIGN_SIZE
to better convey what the alignment factor is used for (and what it is
not used for).
- Removed BLIS_ENABLE_SYSTEM_MEM_ALIGN. Dynamic memory alignment is now
disabled by setting BLIS_HEAP_STRIDE_ALIGN_SIZE to 1.
- Inserted instances of __attribute__((aligned(BLIS_STACK_BUF_ALIGN_SIZE)))
into macro-kernels to specify stack alignment of temporary buffers.
- Modified test suite driver to output new constants.
- Removed bli_align_dim_to_sys() and bli_align_dim_to_cmem(). Instead, we now
use bli_align_dim_to_size(), which takes a third argument (the desired
alignment).
Details:
- Removed the #define of _POSIX_C_SOURCE in bli_config.h (for both reference
and clarksville configurations) and added "-D_POSIX_C_SOURCE=200112L" to
the compiler command line arguments in make_defs.mk (for both configs).
Thanks to Devin Matthews for suggesting this change.
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:
- Renamed BLIS_MEMORY_ALIGNMENT_SIZE to BLIS_CONTIG_MEM_ALIGN_SIZE.
- Renamed BLIS_ENABLE_MEMORY_ALIGNMENT to BLIS_ENABLE_SYSTEM_MEM_ALIGN.
- Added BLIS_SYSTEM_MEM_ALIGN_SIZE, which controls only the alignment
passed into posix_memalign() or equivalent.
- Defined new function, bli_align_dim_to_cmem(), which applies the
contiguous memory alignment (rather than the system/malloc alignment).
Details:
- Removed guard around #define for memory alignment size constant.
Memory alignment should always be enabled, and so this value should
always be defined.
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.
