Efficient N-to-M Checkpointing Algorithm for Finite Element Simulations

Autor: Ham, David A., Hapla, Vaclav, Knepley, Matthew G., Mitchell, Lawrence, Sagiyama, Koki

In this work, we introduce a new algorithm for N-to-M checkpointing in finite element simulations. This new algorithm allows efficient saving/loading of functions representing physical quantities associated with the mesh representing the physical dom

Autor: Schade, Malte, Boesch, Cyrill, Hapla, Vaclav, Fichtner, Andreas

Publikováno v: Schade, M., Boesch, C., Hapla, V., & Fichtner, A. (2024). A quantum computing concept for 1-D elastic wave simulation with exponential speedup. Geophysical Journal International, ggae160

Quantum computing has attracted considerable attention in recent years because it promises speed-ups that conventional supercomputers cannot offer, at least for some applications. Though existing quantum computers are, in most cases, still too small

Fully Parallel Mesh I/O using PETSc DMPlex with an Application to Waveform Modeling

Autor: Hapla, Vaclav, Knepley, Matthew G., Afanasiev, Michael, Boehm, Christian, van Driel, Martin, Krischer, Lion, Fichtner, Andreas

Publikováno v: SIAM J. Sci. Comput. 43 (2021) C127-C153

Large-scale PDE simulations using high-order finite-element methods on unstructured meshes are an indispensable tool in science and engineering. The widely used open-source PETSc library offers an efficient representation of generic unstructured mesh
