Geometry-Aware Computational Meshing in PETSc

Abstract Building on the framework for computational meshing in the PETSc library knepleykarpeev09,knepley2025, we have developed a tightly coupled geometry-discretization infrastructure, enabling geometric data to be used directly in simulation and analysis.

Verifying PETSc Vector Components Using CIVL

Abstract This paper presents a modular approach to verifying the vector module of PETSc, a widely used library in scientific computing, using the CIVL model checker. Our approach relies on the creation of stub functions, which serve a dual purpose of specifying the intended behavior of individual PETSc functions and providing an abstraction ...

PETSc/TAO developments for GPU-based early exascale systems

The International Journal of High Performance Computing Applications
The Portable Extensible Toolkit for Scientific Computation (PETSc) library provides scalable solvers for nonlinear time-dependent differential and algebraic equations and for numerical optimization via the Toolkit for Advanced Optimization (TAO). PETSc is used in dozens of scientific fields and is an important building block for many simulation codes.
