Which data residual norm for robust elastic frequency-domain full waveform inversion? (2010, methodology): “These have been based on direct solvers, iteraive solvers, hybrid direct/iterative solvers, and time-domain aproaches Nihei and Li, 2007; Operto et al., 2007; Plessix, 2007; arner et al., 2007; Sirgue et al., 2008; Sourbier et al., 2008; Etienne t al., 2009 .”
An efficient frequency-domain full waveform inversion method using simultaneous encoded sources (2011, methodology): “However, the time and memory cost of the LU factorization together with its limited scalability on large-scale distributed memory platforms prevents the application of the direct solver to large-scale 3D problems (Operto et al., 2007; Brossier et al., 2010).”
On 3D modeling of seismic wave propagation via a structured parallel multifrontal direct Helmholtz solver (2011, methodology): “Direct factorization methods have the natural advantage that the matrix factorization needs be carried out only once (per frequency), the factors being used in solving fastly the equation for multiple right-hand-sides (Operto et al. 2007, 2009).”
An overview of full-waveform inversion in exploration geophysics (2009, methodology): “However, the time and memory complexities of LU factorization and its limited scalability on large-scale distributed memory platforms prevent use of the approach for large-scale 3D problems (cid:1) i.e., problems involving more than 10 million unknowns; Operto et al., 2007 (cid:2) .”
