Analysis of GPU Power Consumption Using Internal Sensors
Mariza Ferro,André Yokoyama,Vinícius Klôh,Gabrieli Silva,Rodrigo Gandra,Ricardo Braganca,Andre Bulcão,Bruno Schulze +7 more
TL;DR: This work wrote their own tools to query the sensors of two NVIDIA GPUs from different generations and compare the accuracy of them, and compares the power profile of GPU with CPU using IPMItool.
Proceedings ArticleDOI
Energy Estimation Tool FPGA-based Approach for Petroleum Industry
G.S. Menezes,Abel G. Silva-Filho,V.L. Souza,Victor Wanderley Costa de Medeiros,Manoel Eusebio de Lima,Rodrigo Gandra,Ricardo Braganca +6 more
TL;DR: An analysis tool of energy consumption of a seismic application applied to FPGA architecture for a real Brazilian industry and results indicate an increase in efficiency/Joule of about 23 and 1.5 times higher respectively.
Proceedings ArticleDOI
Performance Evaluation Model based on Precision Reduction and FPGAs Applied to Seismic Modeling
Abner Correa Barros,Bruno Holanda Tavares Charamba Dutra,Vinicius V. Brito,Manoel Eusebio de Lima,Abel G. Silva-Filho,Rodrigo Gandra,Ricardo Braganca +6 more
TL;DR: In this paper, a real case study was used in order to evaluate the efficiency of two different metrics applied to this seismic application based on RTM algorithm, and the main strategy is to explore the precision reduction in terms of SNR (Signal-to-Noise Ratio) and UIQI (Universal Image Quality Index) metrics, to improve the performance of the system.
Proceedings ArticleDOI
FPGA-based Accelerator to Speed-up Seismic Applications
Victor Wanderley Costa de Medeiros,Rodrigo Camarotti Ferreira da Rocha,Antonyus P. A. Ferreira,J.C.B.L. Correia,João Paulo Barbosa,Abel G. Silva-Filho,Manoel Eusebio de Lima,Rodrigo Gandra,Ricardo Braganca +8 more
TL;DR: This work presents an FPGA-based solution that explores efficiently the reuse of data and parallelization in both space and time domains for the first computational stage of the RTM (Reverse Time Migration) algorithm, the seismic modeling.
