Details:
- Fixed a makefile error encountered when building the testsuite directly
in its directory (as opposed to indirectly via 'make test'). The fix
involves introducing a new variable, BUILD_PATH, alongside the existing
DIST_PATH variable. By default, BUILD_PATH is set to the current
directory, and is overridden by other Makefiles used by, for example,
the testsuite and standalone test drivers in testsuite or test,
respectively.
- Some files/directories in common.mk were redefined in terms of
BUILD_DIR, such as the locations of config.mk file and the intermediate
include directory.
Details:
- Fixed semi-broken testsuite Makefile and very-broken test driver Makefiles,
as well as those for test/3m4m, test/thread_ranges, and test/exec_sizes
sub-directories.
- Factored out much of the top-level Makefile into common.mk. A Makefile
needs only set DIST_PATH to the relative path to the top level of the
BLIS source distribution before including common.mk in order to acquire
all of the definitions typically needed in a Makefile that tests BLIS.
Details:
- Expanded/updated interface for bli_get_range_weighted() and
bli_get_range() so that the direction of movement is specified in the
function name (e.g. bli_get_range_l2r(), bli_get_range_weighted_t2b())
and also so that the object being partitioned is passed instead of an
uplo parameter. Updated invocations in level-3 blocked variants, as
appropriate.
- (Re)implemented bli_get_range_*() and bli_get_range_weighted_*() to
carefully take into account the location of the diagonal when computing
ranges so that the area of each subpartition (which, in all present
level-3 operations, is proportional to the amount of computation
engendered) is as equal as possible.
- Added calls to a new class of routines to all non-gemm level-3 blocked
variants:
bli_<oper>_prune_unref_mparts_[mnk]()
where <oper> is herk, trmm, or trsm and [mnk] is chosen based on which
dimension is being partitioned. These routines call a more basic
routine, bli_prune_unref_mparts(), to prune unreferenced/unstored
regions from matrices and simultaneously adjust other matrices which
share the same dimension accordingly.
- Simplified herk_blk_var2f, trmm_blk_var1f/b as a result of more the
new pruning routines.
- Fixed incorrect blocking factors passed into bli_get_range_*() in
bli_trsm_blk_var[12][fb].c
- Added a new test driver in test/thread_ranges that can exercise the new
bli_get_range_*() and bli_get_range_weighted_*() under a range of
conditions.
- Reimplemented m and n fields of obj_t as elements in a "dim"
array field so that dimensions could be queried via index constant
(e.g. BLIS_M, BLIS_N). Adjusted/added query and modification
macros accordingly.
- Defined mdim_t type to enumerate BLIS_M and BLIS_N indexing values.
- Added bli_round() macro, which calls C math library function round(),
and bli_round_to_mult(), which rounds a value to the nearest multiple
of some other value.
- Added miscellaneous pruning- and mdim_t-related macros.
- Renamed bli_obj_row_offset(), bli_obj_col_offset() macros to
bli_obj_row_off(), bli_obj_col_off().
