Emmerald: a fast matrix-matrix multiply using Intel's SSE instructions

摘要

Gereralized matrix-matrix multiplication forms the kernel of many mathematical algorithms, hence a faster matrix-matrix multiply immediately benefits these algorithms. In this paper we implement efficient matrix multiplication for large matrices using the Intel Pentium single instruction multiple data (SIMD) floating point architecture. The main difficulty with the Pentium and other commodity processors is the need to efficiently utilize the cache hierarchy, particularly given the growing gap between main-memory and CPU clock speeds.
