Please, bring your own laptop. All the PATC courses at BSC are free of charge.

Course conveners: Herve Petetin and Vladimir Lapin

This training will be online via zoom.

Course lecturers: Earth Sciences Department researchers involved in the group of Computational Earth Sciences, Atmospheric Composition, Climate Prediction and Earth System Services. Final lectures TBA.

Objectives: The objective of this PATC course is to cover the basics of a high performance computing (HPC) environment oriented towards earth science applications, specifically chemical weather modelling and climate modelling.

More precisely, the course will cover:

  • Introduction to earth science fundamentals and modelling;
  • Basic usage of an HPC environment: shell, compilers, libraries, file systems, queuing system and parallel computing.
  • Build and configure targeted earth science applications with the NMMB/BSC-CTM chemical transport model and with the EC-EARTH climate model;
  • Execute and monitor numerical experiments using a workflow manager;
  • Analyse and visualise model outputs with a wide set of tools.

Learning outcomes: Participants will learn and gain experience in accessing an HPC facility, installing earth science numerical models and related utilities and libraries, running numerical simulations, monitoring the execution of supercomputing jobs, analysing and visualising model results.

Level: (All courses are designed for specialists with at least 1st cycle degree or similar background experience)
For trainees with some theoretical and practical knowledge

At least University degree in progress on Earth Sciences, Computer Sciences or related area
Basic knowledge of UNIX
Knowledge of C, FORTRAN, MPI or openMP is recommended
