Abstract
In this paper, a new methodology for speeding up Matrix–Matrix Multiplication
using Single Instruction Multiple Data unit, at one and more cores having a
shared cache, is presented. This methodology achieves higher execution speed than
ATLAS state of the art library (speedup from 1.08 up to 3.5), by decreasing the number
of instructions (load/store and arithmetic) and the data cache accesses and misses in
thememory hierarchy. This is achieved by fully exploiting the software characteristics
(e.g. data reuse) and hardware parameters (e.g. data caches sizes and associativities)
as one problem and not separately, giving high quality solutions and a smaller search
space.
