Discovering Faster Linear Solvers for FLASH Magnetic-Diffusion Systems
We built a system to discover faster linear solvers for magnetic-diffusion systems arising in FLASH. To ground the discovery process, we assembled an initial dataset of linear systems from parameter variations of AlWire problems 1 and 2 and the ZPinch example, together with two MagDiff unit tests: the implicit-AMR test and the edge test. We achieved a 1.546× speedup (54.6%) over baseline.
