Details:
- Removed trailing commas from enums in bli_type_defs.h. Thanks to
Erling Andersen for pointing out this inconsistency and suggesting
the change.
Details:
- Added explicit handling of situations where i == dim to
bli_determine_blocksize_b_sub(). This isn't actually needed by any
current use case within BLIS, but handling the situation is nonetheless
prudent. Thanks to Minh Quan for reporting this issue and requesting
the fix.
Details:
- Fixed a bug in bli_l3_packm() that caused cntl_t-cached packed mem_t
entries to be released and then re-acquired unnecessarily. (In essence,
the "<" operands in the conditional that guards the
release-and-reacquire code block simply needed to be swapped.) The bug
should have only affected performance (rather than the computed result).
Thanks to Minh Quan for identifying and reporting the bug.
Details:
- Removed the family field inside the cntx_t struct and re-added it to the
cntl_t struct. Updated all accessor functions/macros accordingly, as well
as all consumers and intermediaries of the family parameter (such as
bli_l3_thread_decorator(), bli_l3_direct(), and bli_l3_prune_*()). This
change was motivated by the desire to keep the context limited, as much
as possible, to information about the computing environment. (The family
field, by contrast, is a descriptor about the operation being executed.)
- Added additional functions to bli_blksz_*() API.
- Added additional functions to bli_cntx_*() API.
- Minor updates to bli_func.c, bli_mbool.c.
- Removed 'obj' from bli_blksz_*() API names.
- Removed 'obj' from bli_cntx_*() API names.
- Removed 'obj' from bli_cntl_*(), bli_*_cntl_*() API names. Renamed routines
that operate only on a single struct to contain the "_node" suffix to
differentiate with those routines that operate on the entire tree.
- Added enums for packm and unpackm kernels to bli_type_defs.h.
- Removed BLIS_1F and BLIS_VF from bszid_t definition in bli_type_defs.h.
They weren't being used and probably never will be.
Details:
- Dropped 'u' from the list of modifiers passed into the library archiver
ar. Previously, "cru" was used, while now we employ only "cr". This
change was prompted by a warning observed on Ubuntu 16.04:
ar: `u' modifier ignored since `D' is the default (see `U')
This caused me to realize that the default mode causes timestamps to be
zero, and thus the 'u' option, which causes only changed object files to
be inserted, is not applicable.
Details:
- Added an option to configure that allows the user to force an arbitrary
version string at configure-time. The help text also now describes the
usage information.
- Changed the way the version string is communicated to the Makefile.
Previously, it was read into the VERSION variable from the 'version' file
via $(shell cat ...). Now, the VERSION variable is instead set in
config.mk (via a configure-substituted anchor from config.mk.in).
Details:
- Updated the non-tree openmp and pthreads barriers defined in
bli_thrcomm_openmp.c and bli_thrcomm_pthreads.c to instead call a common
implementation in bli_thrcomm.c, bli_thrcomm_barrier_atomic(). This new
implementation goes through the same motions as the previous codes, but
protects its loads and increments with GNU atomic built-ins. These atomic
statements take memory ordering parameters that allow us to specify just
enough constraints for the barrier to work as intended on weakly-ordered
hardware. The prior implementation was only guaranteed to work on systems
with strongly- ordered memory. (Thanks to Devin Matthews for suggesting
this change and his crash-course in atomics and memory ordering.)
- Removed 'volatile' from structs' barrier field declarations in
bli_thrcomm_*.h.
- Updated bli_thrcomm_pthread.? files to use renamed struct barrier fields
consistent with that of the _openmp.? files.
- Updated other bli_thrcomm_* files to rename "communicator" variables to
simply "comm".
Details:
- Renamed bli_env_get_nway() -> bli_thread_get_env().
- Added bli_thread_set_env() to allow setting environment variables
pertaining to multithreading, such as BLIS_JC_NT or BLIS_NUM_THREADS.
- Added the following convenience wrapper routines:
bli_thread_get_jc_nt()
bli_thread_get_ic_nt()
bli_thread_get_jr_nt()
bli_thread_get_ir_nt()
bli_thread_get_num_threads()
bli_thread_set_jc_nt()
bli_thread_set_ic_nt()
bli_thread_set_jr_nt()
bli_thread_set_ir_nt()
bli_thread_set_num_threads()
- Added #include "errno.h" to bli_system.h.
- This commit addresses issue #140.
- Thanks to Chris Goodyer for inspiring these updates.
Details:
- Renamed all level-3 induced method files to use the "_vir.c" suffix
instead of "_ref.c". Also renamed functions within these files
accordingly.
- Renamed cpp macro definitions in frame/ind/include according to the
above changes.
- Removed frame/3/old.
