PMEvo: portable inference of port mappings for out-of-order processors by evolutionary optimization
Fabian Ritter, Sebastian Hack · 2020
Achieving peak performance in a computer system requires optimizations in every layer of the system, be it hardware or software. A detailed understanding of the underlying hardware, and especially the processor, is crucial to optimize software. One key criterion for the performance of a processor is its ability to exploit instruction-level parallelism. This ability is determined by the port mapping of the processor, which describes the execution units of the processor for each instruction.
