Predicting batch queue job wait times for informed scheduling of urgent HPC workloads

no code implementations28 Apr 2022 Nick Brown, Gordon Gibb, Evgenij Belikov, Rupert Nash

We demonstrate that our techniques deliver the most accurate predictions across our machines of interest, with the result of this work being the ability to predict job start times within one minute of the actual start time for around 65\% of jobs on ARCHER2 and 4-cabinet, and 76\% of jobs on Cirrus.

Machine Learning for Gas and Oil Exploration

no code implementations4 Oct 2020 Vito Alexander Nordloh, Anna Roubícková, Nick Brown

Drilling boreholes for gas and oil extraction is an expensive process and profitability strongly depends on characteristics of the subsurface.

Machine learning on Crays to optimise petrophysical workflows in oil and gas exploration

no code implementations1 Oct 2020 Nick Brown, Anna Roubickova, Ioanna Lampaki, Lucy MacGregor, Michelle Ellis, Paola Vera de Newton

With a general aim of decreasing the petrophysical interpretation time down from over 7 days to 7 minutes, in this paper we describe the use of mathematical models that have been trained using raw well log data, for completing each of the four stages of a petrophysical interpretation workflow, along with initial data cleaning.
