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) […]

Trends in bird abundance differ among protected forests but not bird guilds

Kavli Affiliate: Jeffrey F. Miller | First 5 Authors: Jeffrey W. Doser, Aaron S. Weed, Elise F. Zipkin, Kathryn M. Miller, Andrew O. Finley | Summary: Improved monitoring and associated inferential tools to efficiently identify declining bird populations, particularly of rare or sparsely distributed species, is key to informed conservation and management across large spatio-temporal […]

An Improved Dynamical Model for the Microquasar XTE J1550-564

Kavli Affiliate: Jeffrey F. Miller | First 5 Authors: Jerome A. Orosz, James F. Steiner, Jeffrey E. McClintock, Manuel A. P. Torres, Ronald A. Remillard | Summary: We present an improved dynamical model of the X-ray binary and microquasar XTE J1550-564 based on new moderate-resolution optical spectroscopy and near-infrared photometry. By combining our new radial […]
