GenASiS: General Astrophysical Simulation System. II. Self-gravitating Baryonic Matter
Christian Y. Cardall, Reuben D. Budiardja, R. Daniel Murphy +1
GenASiS (General Astrophysical Simulation System) is a code being developed initially and primarily, though not exclusively, for the simulation of core-collapse supernovae on the w…
Dynamical Dark Energy Imprints in the Lyman-Alpha Forest
Diego Garza, Brant Robertson, Piero Madau +7
The nature of dark energy (DE) remains elusive, even though it constitutes the dominant energy-density component of the Universe and drives the late-time acceleration of cosmic exp…
Simulating many-engine spacecraft: Exceeding 1 quadrillion degrees of freedom via information geometric regularization
Benjamin Wilfong, Anand Radhakrishnan, Henry Le Berre +9
We present an optimized implementation of the recently proposed information geometric regularization (IGR) for unprecedented scale simulation of compressible fluid flows applied to…
MFC 5.0: An exascale many-physics flow solver
Benjamin Wilfong, Henry A. Le Berre, Anand Radhakrishnan +16
Many problems of interest in engineering, medicine, and the fundamental sciences rely on high-fidelity flow simulation, making performant computational fluid dynamics solvers a mai…
OpenACC offloading of the MFC compressible multiphase flow solver on AMD and NVIDIA GPUs
Benjamin Wilfong, Anand Radhakrishnan, Henry A. Le Berre +3
GPUs are the heart of the latest generations of supercomputers. We efficiently accelerate a compressible multiphase flow solver via OpenACC on NVIDIA and AMD Instinct GPUs. Optimiz…
Experiences Readying Applications for Exascale
Paul T. Bauman, Reuben D. Budiardja, Dmytro Bykov +29
The advent of exascale computing invites an assessment of existing best practices for developing application readiness on the world's largest supercomputers. This work details obse…
