PROFILE
Jonas Plank
Contributed to the dealii/dealii repository by developing three core features over two months, focusing on enhancing parallel matrix operations and test reliability. Leveraging C++ and MPI programming, extended the PETScWrappers::MPI module with a FullMatrix API and introduced centralized utilities for MPI process information, improving code clarity and maintainability. Implemented a scalar assignment operator for matrices and expanded support for affine constraints with MPI-enabled PETSc FullMatrix, enabling more scalable parallel constraint handling. Emphasized robust engineering practices by strengthening unit and integration test coverage, reducing test flakiness, and ensuring reliable solver verification for large-scale numerical simulations and parallel computing workflows.

Jun 1, 2026June 2026: Delivered two core features for dealii/dealii with expanded test coverage and no reported major bugs. Feature 1: Matrix scalar assignment operator with tests validating solver functionality via PETSc FullMatrix and Vector (commit efeab16e25c0c554e6a80be74441d8412de6c6ec). Feature 2: MPI-enabled PETSc FullMatrix support for affine constraints to enable parallel constraint handling (commit ec05844c3a8ba95197d6dc5e3c6c81e3c945f21a). Impact: improved scalability for large-scale simulations and more reliable solver verification. Technologies/skills: MPI, PETSc, deal.II affine constraints, FullMatrix/Vector, C++, unit/integration testing.
