Details:
- Added a new sandbox called 'gemmlike', which implements sequential and
multithreaded gemm in the style of gemmsup but also unconditionally
employs packing. The purpose of this sandbox is to
(1) avoid select abstractions, such as objects and control trees, in
order to allow readers to better understand how a real-world
implementation of high-performance gemm can be constructed;
(2) provide a starting point for expert users who wish to build
something that is gemm-like without "reinventing the wheel."
Thanks to Jeff Diamond, Tze Meng Low, Nicholai Tukanov, and Devangi
Parikh for requesting and inspiring this work.
- The functions defined in this sandbox currently use the "bls_" prefix
instead of "bli_" in order to avoid any symbol collisions in the main
library.
- The sandbox contains two variants, each of which implements gemm via a
block-panel algorithm. The only difference between the two is that
variant 1 calls the microkernel directly while variant 2 calls the
microkernel indirectly, via a function wrapper, which allows the edge
case handling to be abstracted away from the classic five loops.
- This sandbox implementation utilizes the conventional gemm microkernel
(not the skinny/unpacked gemmsup kernels).
- Updated some typos in the comments of a few files in the main
framework.

Details:
- Removed support for all induced methods except for 1m. This included
removing code related to 3mh, 3m1, 4mh, 4m1a, and 4m1b as well as any
code that existed only to support those implementations. These
implementations were rarely used and posed code maintenance challenges
for BLIS's maintainers going forward.
- Removed reference kernels for packm that pack 3m and 4m micropanels,
and removed 3m/4m-related code from bli_cntx_ref.c.
- Removed support for 3m/4m from the code in frame/ind, then reorganized
and streamlined the remaining code in that directory. The *ind(),
*nat(), and *1m() APIs were all removed. (These additional API layers
no longer made as much sense with only one induced method (1m) being
supported.) The bli_ind.c file (and header) were moved to frame/base
and bli_l3_ind.c (and header) and bli_l3_ind_tapi.h were moved to
frame/3.
- Removed 3m/4m support from the code in frame/1m/packm.
- Removed 3m/4m support from trmm/trsm macrokernels and simplified some
pointer arithmetic that was previously expressed in terms of the
bli_ptr_inc_by_frac() static inline function (whose definition was
also removed).
- Removed the following subdirectories of level-0 macro headers from
frame/include/level0: ri3, rih, ri, ro, rpi. The level-0 scalar macros
defined in these directories were used exclusively for 3m and 4m
method codes.
- Simplified bli_cntx_set_blkszs() and bli_cntx_set_ind_blkszs() in
light of 1m being the only induced method left within BLIS.
- Removed dt_on_output field within auxinfo_t and its associated
accessor functions.
- Re-indexed the 1e/1r pack schemas after removing those associated with
variants of the 3m and 4m methods. This leaves two bits unused within
the pack format portion of the schema bitfield. (See bli_type_defs.h
for more info.)
- Spun off the basic and expert interfaces to the object and typed APIs
into separate files: bli_l3_oapi.c and bli_l3_oapi_ex.c; bli_l3_tapi.c
and bli_l3_tapi_ex.c.
- Moved the level-3 operation-specific _check function calls from the
operations' _front() functions to the corresponding _ex() function of
the object API. (This change roughly maintains where the _check()
functions are called in the call stack but lays the groundwork for
future changes that may come to the level-3 object APIs.) Minor
modifications to bli_l3_check.c to allow the check() functions to be
called from the expert interface APIs.
- Removed support within the testsuite for testing the aforementioned
induced methods, and updated the standalone test drivers in the 'test'
directory so reflect the retirement of those induced methods.
- Modified the sandbox contract so that the user is obliged to define
bli_gemm_ex() instead of bli_gemmnat(). (This change was made in light
of the *nat() functions no longer existing.) Also updated the existing
'power10' and 'gemmlike' sandboxes to come into compliance with the
new sandbox rules.
- Updated BLISObjectAPI.md, BLISTypedAPI.md, Testsuite.md documentation
to reflect the retirement of 3m/4m, and also modified Sandboxes.md to
bring the document into alignment with new conventions.
- Updated various comments; removed segments of commented-out code.
- Add a testsuite for gathering performance (in GFLOPs) and measuring correctness for the POWER10 GEMM reduced precision/integer kernels.
- Reworked GENERIC_GEMM template to hardcode the cache parameters.
- Remove kernel wrapper that checked that only allowed matrices that weren't transposed or conjugated. However, the kernels still assume the matrices are not transposed. This wrapper was removed for performance reasons.
- Renamed and restructured files and functions for clarity.
- Editted the POWER10 document to reflect new changes.

Details:
- This commit adds a new BLIS sandbox that (1) provides implementations
based on low-precision gemm kernels, and (2) extends the BLIS typed
API for those new implementations. Currently, these new kernels can
only be used for the POWER10 microarchitecture; however, they may
provide a template for developing similar kernels for other
microarchitectures (even those beyond POWER), as changes would likely
be limited to select places in the microkernel and possibly the
packing routines. The new low-precision operations that are now
supported include: shgemm, sbgemm, i16gemm, i8gemm, i4gemm. For more
information, refer to the POWER10.md document that is included in
'sandbox/power10'.
