Evaluating performance and portability of high-level programming models: Julia, Python/Numba, and Kokkos on exascale nodes

Kavli Affiliate: Jeffrey F. Miller | First 5 Authors: William F. Godoy, Pedro Valero-Lara, T. Elise Dettling, Christian Trefftz, Ian Jorquera | Summary: We explore the performance and portability of the high-level programming models: the LLVM-based Julia and Python/Numba, and Kokkos on high-performance computing (HPC) nodes: AMD Epyc CPUs and MI250X graphical processing units (GPUs) […]

A Distributionally Robust Random Utility Model

Kavli Affiliate: David Muller | First 5 Authors: David Müller, Emerson Melo, Ruben Schlotter, , | Summary: This paper introduces the distributionally robust random utility model (DRO-RUM), which allows the preference shock (unobserved heterogeneity) distribution to be misspecified or unknown. We make three contributions using tools from the literature on robust optimization. First, by exploiting […]

Improved bounds on the bosonic dark matter with pulsars in the Milky Way

Kavli Affiliate: Lijing Shao | First 5 Authors: Dicong Liang, Lijing Shao, , , | Summary: Neutron stars (NSs) can be used to constrain dark matter (DM) since a NS can transform into a black hole (BH) if it captures sufficient DM particles and exceeds the Chandrasekhar limit. We extend earlier work and for the […]
