When parallel speedups hit the memory wall
Alex F. A. Furtunato, Kyriakos Georgiou, Kerstin Eder +1
After Amdahl's trailblazing work, many other authors proposed analytical speedup models but none have considered the limiting effect of the memory wall. These models exploited aspe…

Energy-Optimal Configurations for Single-Node HPC Applications
Vitor R. G. Silva, Alex Furtunato, Kyriakos Georgiou +2
Energy efficiency is a growing concern for modern computing, especially for HPC due to operational costs and the environmental impact. We propose a methodology to find energy-optim…

The Benefits of Low Operating Voltage Devices to the Energy Efficiency of Parallel Systems
Samuel Xavier-de-Souza, Eduardo A. Neves, Alex F. A. Furtunato +3
Programmable circuits such as general-purpose processors or FPGAs have their end-user energy efficiency strongly dependent on the program that they execute. Ultimately, it is the p…
