April tea-time: Parthenon – a performance portable block-structured adaptive mesh refinement framework
April 15th 2026: Kokkos tea-time
CExA organizes the 18th Kokkos tea-time on Wednesday, April the 15th, 2026 for 45min starting at 7AM Pacific, 10AM Eastern, 4PM Paris, 11PM Tokyo. It can be followed on Zoom, or by phone.
Philipp Grete will give a talk entitled “Parthenon – a performance portable block-structured adaptive mesh refinement framework”
Philipp Grete is a postdoctoral research associate at the University of Hamburg. His interdisciplinary research covers both physics, e.g., turbulence or (astrophysical) plasma modeling and their role in (astro)physical systems, and computer science, e.g., parallelization and HPC, as well as topics in between such as computational fluid dynamics and numerical methods. Philipp is an advocate of open source, community projects and sustainable software development practices.
Parthenon – a performance portable block-structured adaptive mesh refinement framework
Parthenon is an open source, massively parallel, block-structured, adaptive mesh refinement framework. We are using Kokkos for on-node device parallelization and MPI for inter-node parallelization reaching 92% weak scaling parallel efficiency going from a single to 9,216 nodes (73,728 logical GPUs) on Frontier. It is the basis for various downstream codes across disciplines from astrophysical magnetohydrodynamics to multi-material laboratory physics. In this talk, I will highlight our performance-motivated key design decisions in developing Parthenon such as logical packing of variable and meshblocks, and coalesced communication patterns via direct, asynchronous device-to-device messages. Moreover, I will highlight key features of Parthenon such as sparsely allocated variables, integrated solvers, type-based variable indexing, or a flexible directed, graph based tasking.
