We compare different Poisson solvers within the context of an electrostatic Vlasov-Poisson system. These schemes are implemented as part of the IPPL (Independent Parallel Particle Layer) library, which provides performance portable and dimension independent building blocks for scientific simulations requiring particle-mesh methods, with Eulerian (mesh-based) and Lagrangian (particle-based) approaches.The simulation used to compare the performance and portability of the schemes is Landau damping, part of a set of mini-applications implemented to benchmark and showcase the capabilities of the IPPL library.

The nonuniform fast Fourier transform (NUFFT) enables spectral methods for problems with irregularly spaced samples, with applications in medical imaging, molecular dynamics, and kinetic plasma simulations. Existing GPU implementations are limited to shared-memory execution, restricting problem sizes to what fits on a single node. [...]

We summarize the panel discussion on the future of computing held at LATTICE 2025 in Mumbai, India. The panel brought together experts in lattice gauge theory, high-performance computing, machine learning, and quantum computing to assess emerging opportunities and challenges for lattice field theory research.
