Performance Evaluation of Adaptive-Precision SpMV with Reduced-Precision Formats
Résumé
This study explores the potential for performance improvement in the adaptive-precision sparse matrix-vector product (SpMV) (Graillat et al. 2023) by using reduced-precision formats other than the IEEE standard ones. In addition to FP32 and FP64, we consider to utilize reduced-precision formats of 8/16/24/40/48/56-bit length. Our evaluation compares the performance of four- and nine-precision versions with that of the existing two-precision only version using FP32 and FP64 and demonstrates the effectiveness.
