HPC, architectures et performances

Les unités de traitement parallèles sont maintenant partout. Depuis les tablettes connectées jusqu'aux supercalculateurs des grands laboratoires nationaux, l'utilisation de leurs nouvelles fonctionnalités nécessite une compréhension du fonctionnement des algorithmes distribués et des caractéristiques intrinsèques de leurs architectures. Dans cet exposé, nous ferons un tour d'horizon rapide des principes des diverses architectures actuelles, de l'algorithmique parallèle et de la manière de comprendre les performances de ces algorithmes.

Simulation of HPC systems part 1

The first part of the tutorial will present and contrast current experimental methodologies, giving attendees in-depth understanding of the scientific and technological issues at hand. The second part of the tutorial will focus on simulation, giving a state of the art of current simulation technology and discussing challenges for the development of sound simulation models. The tutorial will use the SimGrid simulation framework as an exemplar since it implements sophisticated and validated simulation models. The last part of the tutorial will ...

Instrumentation and Analysis part 1

In a first part, we will present the basics of tracing and what the major issues are. We will present some of the main tracing environments and try to compare them. We will focus on extrae and present some mechanisms that allow to increase scalability. We will also describe some of the analysis capabilities motivating such mechanisms and how to use them. In particular, we will present a couple of recent developments with clustering and processing sampled data ("folding"). We will illustrate the resulting analysis with paraver. ...

Jdev2017 : T8_Ap03 : Initiation Mpi Communication Point À Point

Cet atelier préparatoire va permettre d’aborder la simulation parallèle à travers les communications entre machines. Les primitives de communication de la bibliothèque MPI qui peuvent être utilisées pour la programmation parallèle, seront présentées. Un exemple d’utilisation de ces primitives sera abordé durant cet atelier.Plus d'informations sur l'atelier préparatoire

Best Practices for Reproducible Research part 1

The aim of this tutorial is to sensibilize the audience to the experiment and analysis reproducibility issue in particular in computer science. I will present tools that help answering the analysis problem and may also reveal useful for managing the experimental process through notebooks. More precisely, I will introduce the audience to the following tools: R and ggplot2 that provide a standard, efficient and flexible data management and graph generation mechanism. Although R is quite cumbersome at first for computer ...
