PhD short course:

Evaluation of Biological and Environmental Systems models with Global Sensitivity and Uncertainty Analysis using state-of-the art High Performance Computing (HPC)

21-23 Octobre 2019

By Prof. R. Munoz-Carpena, Agricultural & Biological Engineering Department , University of Florida Gainesville Florida (USA)

The objective of this hands-on workshop is to teach participants on the use and opportunities of High-Performance Computing for the evaluation of biological systems models. First, with support for UCLouvain CISM-CÉCI we will introduce students to the HPC environment (computer cluster, general unix scripts and file manipulation, SLURM job submission and control). Students will be facilitated a temporary CISM-CÉCI account to practice and later on perform a full Global Sensitivity and Uncertainty Analysis (GSUA) of a generic example prey-predator model. Second, we will present a review of GSUA for a broad audience and how to implement it with any type of simulation models in the CISM-CÉCI HPC. We will use the general prey-predator model to systematically investigate the important drivers of the system populations and identify how we can influence the system to obtain a stable population. The course is designed to attract a broad range of biological and environmental systems modelers, engineers and other disciplines interested in learning and exploring the opportunities of GSUA and HPC as a powerful model-independent framework for model development and testing.

Logistics

The school is organised by the FNRS thematic doctoral school ENVITAM (Environmental Science Technology and Managament) in association with the Sciences and Technology Sector of UCLouvain and the CISM team of UCLouvain. Participation is free of charge, but the school is open for maximum 25 PhD students. Drinks and lunches will be offered to participants. The first registered first served principle will be used.
