Heterogeneous many-cores are now an integral part of modern computing systems ranging
from embedding systems to supercomputers. While heterogeneous many-core design offers …

We present a highly scalable demonstration of a portable asynchronous many-task
programming model and runtime system applied to a grid-based adaptive mesh refinement …

Meeting both scalability and performance portability requirements is a challenge for any
HPC application, especially for adaptively refined ones. In Octo-Tiger, an astrophysics …

Modern calculation codes used in supercomputing are very demanding of computing
resources. For their effective appliance requires the use of parallelization at all levels …

Octo-Tiger, a large-scale 3D AMR code for the merger of stars, uses a combination of HPX,
Kokkos and explicit SIMD types, aiming to achieve performance-portability for a broad range …
