This is the repository for the CWI Research Semester Programme Uncertainty Quantification for High-Dimensional Problems..
The slides from Derek Groen (Wednesday) are available here: https://docs.google.com/presentation/d/1o-9qoy1_znTlxuMLCfeJq52uO_b3N14eQa5iMlmM4FU/edit?usp=drive_link
The lecture on Wednesday (October 9th) includes exercises on submitting ensemble runs on the ARCHER2 supercomputer, provided by UKRI, EPCC, HPE Cray and the University of Edinburgh. These resources are made available through the SEAVEA project (Software Environment for Actionable & VVUQ-evaluated Exascale Applications).
It is strongly suggested that all course participants aquire a SAFE account and course project accounts in good time well before the 9th of October.
The course project has been created, namely ta171 - 241009 SEAVEA training day, and is ready for use until the 8th of November 2024. All users of this project must have an account on the SAFE, which is EPCC's web-based administration portal, wherein users can request access to projects on any of EPCC's services. To get an account on SAFE, please visit [1]. You are required to use an institutional email address, e.g. not gmail.com, and also provide your public ssh key. Also, to make a SAFE account you will need to provide an "institute for reporting". Please select University College London.
To join the course project, hover over the Projects button along the top banner, and click on 'Request access', then enter 'ta171' to locate our course project, then click Apply.
A quick-start guide on how to use Archer2 can be found here [2], with the full user guide here [3].
NB: Archer2 charges per node, so a 4-core job running for an hour will cost 128 core hours (=1CU, where a CU is 1 node hour). As such, an ill-formed batch script can be expensive, e.g., request 10 hours on multiple nodes and forget a carriage return on the srun command.
The account code/budget to use in batch scripts is ta171, how to enter this will be made clear in the lecture.
