Anomalous-diffusion synthesis of non-Gaussian reservoir anomalies for time-lapse seismic inversion
Anderson Mateus de Sousa Nogueira, Paulo Vitor Ferreira, Katerine Rincon Perez +5
We develop a physics-informed framework for learned time-lapse (4D) seismic inversion that estimates production-induced velocity changes associated with subsurface fluid migration.…
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…
PATSMA: Parameter Auto-tuning for Shared Memory Algorithms
Joao B. Fernandes, Felipe H. S. da Silva, Samuel Xavier-de-Souza +1
Programs with high levels of complexity often face challenges in adjusting execution parameters, particularly when these parameters vary based on the execution context. These dynam…
