Details:
- Fixed a couple of bugs that affected OpenMP and POSIX threads
configurations that resulted in compiler errors and warnings due
to type mismatch, and in the case of pthreads, a missing function
argument. The bugs are fairly recent, introduced in a017062.
Details:
- Integrated a patch originally authored and submitted by Ricardo Magana
of HP Enterprise. The changeset inserts use of a new object type, membrk_t,
(memory broker) that allows multiple sets of memory pools on, for example,
separate NUMA nodes, each of which has a separate memory space.
- Added membrk field to cntx_t and defined corresponding accessor macros.
- Added membrk field to mem_t object and defined corresponding accessor macros.
- Created new bli_membrk.c file, which contains the new memory broker API,
including:
bli_membrk_init(), bli_membrk_finalize()
bli_membrk_acquire_[mv](), bli_membrk_release(),
bli_membrk_init_pools(), bli_membrk_reinit_pools(),
bli_membrk_finalize_pools(),
bli_membrk_pool_size()
- In bli_mem.c, changed function calls to
bli_mem_init_pools() -> bli_membrk_init()
bli_mem_reinit_pools() -> bli_membrk_reinit()
bli_mem_finalize_pools() -> bli_membrk_finalize()
- In bli_packv_init.c, bli_packm_init.c, changed function calls to:
bli_mem_acquire_[mv]() -> bli_membrk_acquire_[mv]()
bli_mem_release() -> bli_membrk_release()
- Added bli_mutex.c and related files to frame/thread. These files define
abstract mutexes (locks) and corresponding APIs for pthreads, openmp, or
single-threaded execution. This new API is employed within functions
such as bli_membrk_acquire_[mv]() and bli_membrk_release().
Details:
- Reorganized code and renamed files defining APIs related to multithreading.
All code that is not specific to a particular operation is now located in a
new directory: frame/thread. Code is now organized, roughly, by the
namespace to which it belongs (see below).
- Consolidated all operation-specific *_thrinfo_t object types into a single
thrinfo_t object type. Operation-specific level-3 *_thrinfo_t APIs were
also consolidated, leaving bli_l3_thrinfo_*() and bli_packm_thrinfo_*()
functions (aside from a few general purpose bli_thrinfo_*() functions).
- Renamed thread_comm_t object type to thrcomm_t.
- Renamed many of the routines and functions (and macros) for multithreading.
We now have the following API namespaces:
- bli_thrinfo_*(): functions related to thrinfo_t objects
- bli_thrcomm_*(): functions related to thrcomm_t objects.
- bli_thread_*(): general-purpose functions, such as initialization,
finalization, and computing ranges. (For now, some macros, such as
bli_thread_[io]broadcast() and bli_thread_[io]barrier() use the
bli_thread_ namespace prefix, even though bli_thrinfo_ may be more
appropriate.)
- Renamed thread-related macros so that they use a bli_ prefix.
- Renamed control tree-related macros so that they use a bli_ prefix (to be
consistent with the thread-related macros that were also renamed).
- Removed #undef BLIS_SIMD_ALIGN_SIZE from dunnington's bli_kernel.h. This
#undef was a temporary fix to some macro defaults which were being applied
in the wrong order, which was recently fixed.
