ItemGeodynamic benchmarking tests in HPCFarrington, R ; Moresi, L ; Quenette, S ; Turnbull, R ; SUNTER, P (Australian Partnership for Advanced Computing, 2005)The increase in large science focused computational frameworks has raised many issues involving the ability to maintain accurate scientific benchmarks throughout the ongoing evolution of the code. These science based tests allow not only developers access to the latest updates, but the science users as well. It is these scientific tests required for geodynamic code benchmarking in a HPC environment that are investigated. The importance of benchmarking in computational science, for both quality assurance and reliability, is discussed and a case study for thermochemical convection modelling is presented. The implementation of automated testing for science units is described with particular attention to the problems arising from science tests compared to traditional computational tests.

ItemSlip rate estimation from tilting of marine terraces above an offshore listric thrust fault, Kaikoura, New ZealandDuffy, B ; Clark, KJ ; Upton, P ; Langridge, R ; Kelly, K ; Hammond, K (GNS Science, 2017-11-13)Slip on an offshore fault uplifted and tilted the Kaikoura Peninsula during the 2016 Kaikoura earthquake. Analysis of a 2012, 1m Lidar DEM shows that the uplifted Kaikoura marine terraces have been progressively tilted in the same manner since 120 ka. A Monte-Carlo analysis of tilt-age relationships, based on a model of listric faulting, and using published age data and Papuan and regional sea level curves, implies that slip rates have increased from 2.3 ± 1.3 mm/yr to 4.1 ± 1.2 mm/yr since c.60 ka. Comparison of the elevation of young, uplifted beaches surrounding the peninsula, with a Late Holocene sea level curve, suggests three earthquake events (including 2016) over 3 kyr. The timing of the earthquakes implies lower Late Holocene slip rates, compared with post-60 ka slip rates; comparison of these events with paleoseismic records of the Marlborough Fault System is interpreted to suggest latest Holocene clustering of seismicity.
