The PETSc Community Is the Infrastructure
Mark Adams, Satish Balay, Oana Marin +13
The communities who develop and support open source scientific software packages are crucial to the utility and success of such packages. Moreover, these communities form an import…
Understanding performance variability in standard and pipelined parallel Krylov solvers
Hannah Morgan, Patrick Sanan, Matthew G. Knepley +1
In this work, we collect data from runs of Krylov subspace methods and pipelined Krylov algorithms in an effort to understand and model the impact of machine noise and other source…
Vertically resolved magma ocean-protoatmosphere evolution: H, HO, CO, CH, CO, O, and N as primary absorbers
Tim Lichtenberg, Dan J. Bower, Mark Hammond +4
The earliest atmospheres of rocky planets originate from extensive volatile release during magma ocean epochs that occur during assembly of the planet. These establish the initial…
Linking the evolution of terrestrial interiors and an early outgassed atmosphere to astrophysical observations
Dan J. Bower, Daniel Kitzmann, Aaron S. Wolf +3
A terrestrial planet is molten during formation and may remain so if subject to intense insolation or tidal forces. Observations continue to favour the detection and characterisati…
Numerical solution of a non-linear conservation law applicable to the interior dynamics of partially molten planets
Dan J. Bower, Patrick Sanan, Aaron S. Wolf
The energy balance of a partially molten rocky planet can be expressed as a non-linear diffusion equation using mixing length theory to quantify heat transport by both convection a…
Extreme-scale Multigrid Components within PETSc
Dave A. May, Patrick Sanan, Karl Rupp +2
Elliptic partial differential equations (PDEs) frequently arise in continuum descriptions of physical processes relevant to science and engineering. Multilevel preconditioners repr…
