Talk by Robin Boezennec

On October, 11th, Robin Boezennec, PhD Student in TADaaM team, will presents us the work he has done during his interneship.

Title: Stochastic execution time modelling to improve scheduling performance in high performance computing

Current batch schedulers are based on the use of a user-provided execution time estimate. It is known that this estimate is almost always wrong. One direction of research is therefore to try to accurately predict the execution time of tasks, in particular via the analysis of their code. However, this approach has never succeeded. We assume that exact prediction of execution times is too complicated to be profitable, if not impossible. We will therefore consider execution times as random variables, use statistics to qualify them, and incorporate this knowledge into the batch scheduler. This presentation will present the first results obtained during a pre-thesis internship.
