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 ``` zen4 new 64, 24576, 3072, add=0, MatTA=bf16, MatTB=sfp: 616.6 GFLOPS. 64, 3072, 24576, add=0, MatTA=bf16, MatTB=sfp: 460.7 GFLOPS. 64, 24576, 3072, add=0, MatTA=f32, MatTB=sfp: 598.6 GFLOPS. 64, 3072, 24576, add=0, MatTA=f32, MatTB=sfp: 435.6 GFLOPS. zen4 old 64, 24576, 3072, add=0, MatTA=f32, MatTB=sfp: 257.5 GFLOPS. 64, 3072, 24576, add=0, MatTA=f32, MatTB=sfp: 231.9 GFLOPS. ``` PiperOrigin-RevId: 663729812	2024-08-16 07:52:20 -07:00
Jan Wassenberg	f9b390b134	Support all weight types in a single binary. This changes the command line flags, but the default value retains the previous behavior. Also add a CreateGemma helper to enable extra args without interface changes. PiperOrigin-RevId: 641266411	2024-06-07 09:04:45 -07:00
Zoltan Szabadka	c004799cdc	Add Adam optimizer. Drive-by: Fix compilation errors and tests for backprop functions.	2024-06-06 18:41:36 +00:00
Jan Wassenberg	57c2cd8b52	Simplifications: remove GemmaInterface and GemmaImpl Split common and weights into separate lib Remove common-inl (does not have to be SIMD code), activations.cc Centralize switch(Model) to avoid duplication Move CompressWeightsT to compress_weights.cc Move LoadWeights to weights.cc PiperOrigin-RevId: 640869202	2024-06-06 05:54:21 -07:00
