Developing multiphysics applications that run on the supercomputers of the exascale era is a daunting task. The varying workload in different regions of a problem can make load balancing difficult, especially when simultaneously handling GPU and CPU resources. Task-based parallelism is a promising way out of this dilemma but it introduces significant complexity for the application developer...
Particle–mesh methods such as Particle-in-Cell (PIC) remain central to plasma, beam, and astrophysical simulation. We present the current state of the IPPL (Independent Parallel Particle Layer) library, which provides performance portable and dimension independent building blocks for scientific simulations requiring particle-mesh methods. IPPL makes use of Kokkos, HeFFTe, and MPI (Message...
This research is in the context of IPPL (Independent Parallel Particle Layer), an open-source C++ framework providing performance-portable, dimension-independent building blocks for particle–mesh simulations, which combine Eulerian field solvers and Lagrangian particle dynamics. IPPL leverages Kokkos for on-node portability, MPI for distributed parallelism, and heFFTe for scalable FFTs,...

Solid-state batteries (SSBs) are a promising technology to overcome physicochemical limitations of the currently dominant battery technology, lithium-ion batteries with liquid electrolytes. However, the interaction between solid mechanics and electrochemical phenomena remains an unresolved challenge in these systems. To gain a deeper understanding, microstructure-resolved computational models...
The 4C (Comprehensive Computational Community Code, https://4c-multiphysics.org) multiphysics simulation framework has been developed to address complex physical phenomena across various scientific and engineering domains. From its inception, 4C has relied on the Trilinos project, an open-source software library for scalable numerical computations, as its backbone for sparse linear algebra and...
