The Vera C. Rubin Observatory Data Preview 1
Vera C Rubin Observatory Team, Tatiana Acero Cuellar, Emily Acosta +325
We present Rubin Data Preview 1 DP1, the first data from the NSF DOE Vera C Rubin Observatory, comprising raw and calibrated single epoch images, coadds, difference images, detecti…
A Distributed-memory Tridiagonal Solver Based on a Specialised Data Structure Optimised for CPU and GPU Architectures
Semih Akkurt, Sébastien Lemaire, Paul Bartholomew +1
Various numerical methods used for solving partial differential equations (PDE) result in tridiagonal systems. Solving tridiagonal systems on distributed-memory environments is not…
Performance and scaling of the LFRic weather and climate model on different generations of HPE Cray EX supercomputers
J. Mark Bull, Andrew Coughtrie, Deva Deeptimahanti +7
This study presents scaling results and a performance analysis across different supercomputers and compilers for the Met Office weather and climate model, LFRic. The model is shown…
The densities in diffuse and translucent molecular clouds: estimates from observations of C and from 3-dimensional extinction maps
David A. Neufeld, Daniel E. Welty, Alexei V. Ivlev +7
Newly-computed collisional rate coefficients for the excitation of C in collisions with H, presented recently by Najar and Kalugina (2020), are significantly larger than th…
Evaluating Total Environmental Impact for a Computing Infrastructure
Adrian Jackson, Jon Hays, Alex Owen +3
In this paper we outline the results of a project to evaluate the total climate/carbon impact of a digital research infrastructure for a defined snapshot period. We outline the car…
Parallel faceted imaging in radio interferometry via proximal splitting (Faceted HyperSARA): II. Code and real data proof of concept
Pierre-Antoine Thouvenin, Arwa Dabbech, Ming Jiang +4
In a companion paper, a faceted wideband imaging technique for radio interferometry, dubbed Faceted HyperSARA, has been introduced and validated on synthetic data. Building on the…
