......Modeling and computation are taking an unprecedented role in the search for, and the extraction of, energy sources like oil and gas. The oil and gas industry already uses high-performance computing (HPC), but it’s still unclear how conventional HPC technologies can meet the demands of tomorrow’s algorithms. In this article, we describe the(More)
Memory-related constraints (memory bandwidth, cache size) are nowadays the performance bottleneck of most computational applications. Especially in the scenario of multiple cores, the performance does not scale with the number of cores in many cases. In our work, we present our FPGA-based solution for the 3D Reverse Time Migration (RTM) algorithm. As the(More)
Depth imaging techniques still face difficulties under the edges of salt bodies. Elf encountered such a problem in a 3-D survey in the North Sea where they hoped to image a reflector that lays beneath a salt body. Based on the 3-D data, Elf created 2-D synthetic model of the salt body and surrounding subsurface. By analyzing this synthetic model using(More)
We distribute the modified normalized cuts image segmentation with random boundaries algorithm on a parallel network to track 3D salt boundaries. We identify two key steps of this algorithm for parallelization. Firstly, we parallelize the calculation of the weight matrix. Secondly, we parallelize the matrix-vector product of the eigenvector calculation.(More)
