## Changes in 0.8.0
November 19, 2020
Improvements present in 0.8.0:
Framework:
- Implemented support for the level-3 operation `gemmt`, which performs a `gemm` on only the lower or only the upper triangle of a square matrix C. For now, only the conventional/large code path (and not the sup code path) is provided. This support also includes `gemmt` APIs in the BLAS and CBLAS compatibility layers. (AMD)
- Added a C++ template header, `blis.hh`, containing a BLAS-inspired wrapper to a set of polymorphic CBLAS-like function wrappers defined in another header, `cblas.hh`. These headers are installed only when running the `install` target with `INSTALL_HH` set to `yes`.
- Disallow `randv`, `randm`, `randnv`, and `randnm` from producing vectors and matrices with 1-norms of zero.
- Changed the behavior of user-initialized `rntm_t` objects so that packing of A and B is disabled by default. (Kiran Varaganti)
- Transitioned to using `bool` keyword instead of the previous integer-based `bool_t` typedef. (RuQing Xu)
- Updated all inline function definitions to use the cpp macro `BLIS_INLINE` instead of the `static` keyword. (Giorgos Margaritis, Devin Matthews)
- Relocated `#include "cpuid.h"` directive from `bli_cpuid.h` to `bli_cpuid.c` so that applications can `#include` both `blis.h` and `cpuid.h`. (Bhaskar Nallani, Devin Matthews)
- Defined `xerbla_array_()` to complement the netlib routine `xerbla_array()`. (Isuru Fernando)
- Replaced the previously broken `ref99` sandbox with a simpler, functioning alternative. (Francisco Igual)
- Fixed a harmless bug whereby `herk` was calling `trmm`-related code for determining the blocksize of KC in the 4th loop.
Kernels:
- Implemented a full set of `sgemmsup` assembly millikernels and microkernels for `haswell` kernel set.
- Implemented POWER10 `sgemm` and `dgemm` microkernels. (Nicholai Tukanov)
- Added two kernels (`dgemm` and `dpackm`) that employ ARM SVE vector extensions. (Guodong Xu)
- Implemented explicit beta = 0 handling in the `sgemm` microkernel in `bli_gemm_armv7a_int_d4x4.c`. This omission was causing testsuite failures in the new `gemmt` testsuite module for `cortexa15` builds given that the `gemmt` correctness check relies on `gemm` with beta = 0.
- Updated `void*` function arguments in reference `packm` kernels to use the native pointer type, and fixed a related dormant type bug in `bli_kernels_knl.h`.
- Fixed missing `restrict` qualifier in `sgemm` microkernel prototype for `knl` kernel set header.
- Added some missing n = 6 edge cases to `dgemmsup` kernels.
- Fixed an erroneously disabled edge case optimization in `gemmsup` variant code.
- Various bugfixes and cleanups to `dgemmsup` kernels.
Build system:
- Implemented runtime subconfiguration selection override via `BLIS_ARCH_TYPE`. (decandia50)
- Output the python found during `configure` into the `PYTHON` variable set in `build/config.mk`. (AMD)
- Added configure support for Intel oneAPI via the `CC` environment variable. (Ajay Panyala, Devin Matthews)
- Use `-O2` for all framework code, potentially avoiding intermitten issues with `f2c`'ed packed and banded code. (Devin Matthews)
- Tweaked `zen2` subconfiguration's cache blocksizes and registered full suite of `sgemm` and `dgemm` millikernels.
- Use the `-fomit-frame-pointer` compiler optimization option in the `haswell` and `skx` subconfigurations. (Jeff Diamond, Devin Matthews)
- Tweaked Makefiles in `test`, `test/3`, and `test/sup` so that running any of the usual targets without having first built BLIS results in a helpful error message.
- Add support for `--complex-return=[gnu|intel]` to `configure`, which allows the user to toggle between the GNU and Intel return value conventions for functions such as `cdotc`, `cdotu`, `zdotc`, and `zdotu`.
- Updates to `cortexa9`, `cortexa53` compilation flags. (Dave Love)
Testing:
- Added a `gemmt` module to the testsuite and a standalone test driver to the `test` directory, both of which exercise the new `gemmt` functionality. (AMD)
- Support creating matrices with small or large leading dimensions in `test/sup` test drivers.
- Support executing `test/sup` drivers with unpacked or packed matrices.
- Added optional `numactl` usage to `test/3/runme.sh`.
- Updated and/or consolidated octave scripts in `test/3` and `test/sup`.
- Increased `dotxaxpyf` testsuite thresholds to avoid false `MARGINAL` results during normal execution. (nagsingh)
Documentation:
- Added Epyc 7742 Zen2 ("Rome") performance results (single- and multithreaded) to `Performance.md` and `PerformanceSmall.md`. (Jeff Diamond)
- Documented `gemmt` APIs in `BLISObjectAPI.md` and `BLISTypedAPI.md`. (AMD)
- Documented commonly-used object mutator functions in `BLISObjectAPI.md`. (Jeff Diamond)
- Relocated the operation indices of `BLISObjectAPI.md` and `BLISTypedAPI.md` to appear immediately after their respective tables of contents. (Jeff Diamond)
- Added missing perl prerequisite to `BuildSystem.md`. (pkubaj, Dilyn Corner)
- Fixed missing `conjy` parameter in `BLISTypedAPI.md` documentation for `her2` and `syr2`. (Robert van de Geijn)
- Fixed incorrect link to `shiftd` in `BLISTypedAPI.md`. (Jeff Diamond)
- Mention example code at the top of `BLISObjectAPI.md` and `BLISTypedAPI.md`.
- Minor updates to `README.md`, `FAQ.md`, `Multithreading.md`, and `Sandboxes.md` documents.
