2024-12-11 06:30:28 -08:00
Ray Smith e69bc3bc1c Added the TensorInfo arg to the compressor so the shape and scale can be output correctly to the file in future.
Corrected some errors in the TensorIndex.

Jan Wassenberg f74d496879 Threading/infra improvements.
* Add Parallelize*Range helpers and partitioning helpers
* Refactor Pinning class, store original affinity (required to construct another NestedPools after pinning happened)

Compress:
* prevent Compress printing stats in tests
* zero-pad tensors

Matmul:
* add matmul_unit_test (TODO) and bench_matmul
* matmul_test: change norm to row vectors (that is what is added) and include bf16 rounding error
* Prepare for L2/L3 retrieval

Ray Smith 0d68555f87 Eliminated TConfig.
Changed CompressedLayer and CompressedWeights to be constructed with an instance of a LayerConfig and WeightsConfig respectively.
Added CompressedModel to remove ByteStorageT and get rid of most of the type casting, as well as allowing the default destructor to be used and work properly.
Adjusted WeightsWrapper and ForwardLayer etc to match.
The only remaining template arg is the weight type.
This enables all the instantiations to be deleted, apart from one per type.
It also enables (but not yet done) the config to be stored in the blob file instead of having to be specified separately.
Reduces the size of the gemma_lib and weights shared libraries by a factor of 4.3 and 3.2 respectively.

Jan Wassenberg 8c0a8834c1 Major compression update, arbitrary-len unpack + new Dot
Compression:
* Implement {any packed} x {bf16, f32} 'Load2' and DecompressAndZeroPad
* New compression test for all packed formats, add to GEMMA_TEST_FILES, remove from sfp/nuq_test
* Decompress->DecompressAndZeroPad, use PackedSpan for args with bounds checking
* NUQ: support arbitrary-length enc/dec
* New compression/shared, remove sfp.h and nuq.h
* Move Store2 into Traits and provide Compress2 wrapper
* Remove unused Decompress()-with-pool overload
* Simplify CompressedArrayLen, rename to CompressedArrayElements
* Remove unused DistortionStats b_l1_

Misc:
* Add compensated and Kahan dot, support any length
* Use same Dot function everywhere
* Move exact arithmetic functions into fp_arith
* use FloatPtr and MatPtr typedefs in tests; less stack usage
* Rename args to packed/raw
* Remove Traits::Name, instead TypeName<T>()
* Move kMaxSFP and kClusters/kGroupSize into Sfp/NuqStream

Jan Wassenberg 301dc8067a Major MatMul update, 1.9-2.3x speedup on Zen4 via bf16 mul
Supports converting all weight/activation formats to native MulT (bf16/f32)

Also:
- ConstMat/MutableMat for const correctness
- Move RowVectorBatch to allocator.h so it can be used from Matmul
- Add matmul.h so MatMulEnv can be used from Activations
- Remove kMaxThreads, detect from PerClusterPools
- Build fix: -inl.h files must be textual_hdrs, and highway.h should precede -inl.h

David Coles 39e385782c Allow building on Windows using `clang-cl` toolchain
It's not possible to build `gemma.cpp` with the standard MSVC front-end
as it doesn't support arrays more than `0x7ffffffff` bytes (see Compiler Error C2148),
however this isn't a problem with the optional Visual Studio Clang/LLVM frontend.

This can be specified using the `-T` flag when running CMake:

```
$ cmake -B build -T ClangCL
$ cmake --build build --config Release
```

Windows doesn't provide `pread`/`pwrite` so this must be emulated using
the `ReadFile`/`WriteFile` Win32 APIs.

`_CRT_SECURE_NO_WARNINGS` is defined to prevent a large number of warnings
about using "depricated" function names (e.g. `close` instead of `_close`).

`NOMINMAX` is defined to prevent the `min`/`max` macros from `windows.h`
from conflicting with expressions like `std::min`. Generally libraries should
avoid including `windows.h` in their public headers or define `WIN32_LEAN_AND_MEAN`
before including the `windows.h` header, but this unfortunately isn't always the case.
