Double-Precision Matrix Multiplication Emulation via Ozaki-II Scheme with FP8 Quantization
Yuki Uchino, Katsuhisa Ozaki, Toshiyuki Imamura
In this paper, we propose a method for emulating double-precision general matrix--matrix multiplication (DGEMM), a fundamental and performance-critical kernel in many high-performa…
Iterative Refinement for a Subset of Eigenvectors of Symmetric Matrices via Matrix Multiplications
Takeshi Terao, Katsuhisa Ozaki, Toshiyuki Imamura +1
We develop an iterative refinement method that improves the accuracy of a user-chosen subset of eigenvectors () of an real symmetric matrix. Using an orthog…
Error Analysis of Matrix Multiplication Emulation Using Ozaki-II Scheme
Yuki Uchino, Katsuhisa Ozaki, Toshiyuki Imamura
The Ozaki-II scheme is an emulation method that leverages the Chinese Remainder Theorem to compute high-precision matrix multiplication via a sequence of low-precision matrix multi…
High-Performance and Power-Efficient Emulation of Matrix Multiplication using INT8 Matrix Engines
Yuki Uchino, Katsuhisa Ozaki, Toshiyuki Imamura
Recent architectures integrate high-performance and power-efficient matrix engines. These engines demonstrate remarkable performance in low-precision matrix multiplication, which i…
Performance Enhancement of the Ozaki Scheme on Integer Matrix Multiplication Unit
Yuki Uchino, Katsuhisa Ozaki, Toshiyuki Imamura
This study was aimed at simultaneously achieving sufficient accuracy and high performance for general matrix multiplications. Recent architectures, such as NVIDIA GPUs, feature hig…
