Auto-Tuning for OpenMP Dynamic Scheduling applied to Full Waveform Inversion
Felipe H. S. da Silva, João B. Fernandes, Idalmis M. Sardina +3
Full Waveform Inversion (FWI) is a widely used method in seismic data processing, capable of estimating models that represent the characteristics of the geological layers of the su…
Adaptive Asynchronous Work-Stealing for distributed load-balancing in heterogeneous systems
João B. Fernandes, Ítalo A. S. de Assis, Idalmis M. S. Martins +2
Supercomputers have revolutionized how industries and scientific fields process large amounts of data. These machines group hundreds or thousands of computing nodes working togethe…
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…
