Top-Down Models across CPU Architectures: Applicability and Comparison in a High-Performance Computing Environment

Autor: Fabio Banchelli, Marta Garcia-Gasulla, Filippo Mantovani

Publikováno v: Information, Vol 14, Iss 10, p 554 (2023)

Top-Down models are defined by hardware architects to provide information on the utilization of different hardware components. The target is to isolate the users from the complexity of the hardware architecture while giving them insight into how effi
