A Portable and Versatile Limited-Memory BFGS Implementation in PETSc/TAO
Hansol Suh, Tobin Isaac, Alp Dener +3
The limited-memory BFGS (L-BFGS) Hessian update scheme is the critical kernel in many quasi-Newton optimization algorithms. The most common approach to implementing L-BFGS uses $2m…
Strong Scaling for Numerical Weather Prediction at Petascale with the Atmospheric Model NUMA
Andreas Müller, Michal A. Kopera, Simone Marras +3
Numerical weather prediction (NWP) has proven to be computationally challenging due to its inherent multiscale nature. Currently, the highest resolution NWP models use a horizontal…
Recursive Algorithms for Distributed Forests of Octrees
Tobin Isaac, Carsten Burstedde, Lucas C. Wilcox +1
The forest-of-octrees approach to parallel adaptive mesh refinement and coarsening (AMR) has recently been demonstrated in the context of a number of large-scale PDE-based applicat…
