4bit gemm implementation with avx using tile.

1.
tile size is 2blk by 4. in case of size less then tile, it reduce to
1blk by 4, 2blk by 1 and lastly 1blk by 1.
with internal kernel, weight and activation are loaded based on SIMD
register width and blk length:
avx2 256bit register, 64 weights and activation are loaded.
   blklen16: 4 blks are computed by the internal kernel
   blklen32: 2 blks are computed by the internal kernel
   blklen64: 1 blk are computed by the internal kernel
   blklen128: 1 blks are computed 2 times by the internal kernel
   blklen16: 1 blks are computed 4 times by the internal kernel

avx512 512bit register, 128 weights and activation are loaded.
   blklen16: 8 blks are computed by the internal kernel
   blklen32: 4 blks are computed by the internal kernel
   blklen64: 2 blk are computed by the internal kernel
   blklen128: 1 blks are computed by the internal kernel
   blklen16: 1 blks are computed 2 times by the internal kernel

2.
blksum is precomputed during prepacking. 
computation is reformed:
Sum1(scale_a * scale_b * Sum_blk(a_i * b_i)) + Sum2(blksum_a * blksum_b)
  Sum_blk is over one blk
  Sum1 is over all blks for one output
  Sum2 is over all blks for one output
Sum is computed with sgemm with the current implementation. Further
improvement is possible.

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.

ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.

ONNX Runtime training can accelerate the model training time on multi-node NVIDIA GPUs for transformer models with a one-line addition for existing PyTorch training scripts. Learn more →
