We introduce a new open-source software library $ Jet $, which uses task-based parallelism
to obtain speed-ups in classical tensor-network simulations of quantum circuits. These …

Was Betelgeuse once in a binary star system? What causes it to vary over a vast range of
timescales? Why did it dim dramatically in 2020? When and how will it explode? J. Craig …

We study the properties of double white dwarf (DWD) mergers by performing hydrodynamic
simulations using the new and improved adaptive mesh refinement code octo-tiger. We …

We investigate the merger between a 16M⊙ star, on its way to becoming a red supergiant
(RSG), and a 4M⊙ main-sequence companion. Our study employs three-dimensional …

Between a widening range of GPU vendors and the trend of having more GPUs per compute
node in supercomputers such as Summit, Perlmutter, Frontier and Aurora, develo** …

Ranging from NVIDIA GPUs to AMD GPUs and Intel GPUs: Given the heterogeneity of
available accelerator cards within current supercomputers, portability is a key aspect for …

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

Currently, technological development has exponentially fostered a growing collection of
dispersed and diversified information. In the case of galaxy interaction studies, it is important …

Abstract Asynchronous Many-Task (AMT) runtime systems take advantage of multi-core
architectures with light-weight threads, asynchronous executions, and smart scheduling. In …

The increasing availability of machines relying on non-GPU architectures, such as ARM
A64FX in high-performance computing, provides a set of interesting challenges to …
