Research Projects

Current projects:

    • ESCAPE-2 (2018-2021) will in particular prepare weather and climate domain benchmarks that will allow a much more realistic assessment of application specific performance on large HPC systems  than current generic benchmarks such as HPL and HPCG. It continues the pioneering work of the ESCAPE project.
    • ESiWACE: “Centre of Excellence in Simulation of Weather and Climate in Europe” has been funded by the European Commission to substantially improve efficiency and productivity of numerical weather and climate simulation and prepare them for future exascale systems. Overall, the Centre of Excellence prepares the European weather and climate community to make use of future exascale systems in a co-design effort involving modelling groups, computer scientists and HPC industry.
      It supports the end-to-end workflow of global Earth system modelling and is implemented in two projects: ESiWACE (2015-2019) and ESiWACE2 (2019-2022). The aimed global high-resolution simulations will open up entirely new research opportunities and perspectives.
    • VECMA: The purpose of the VECMA project is to enable a diverse set of multiscale, multiphysics applications — from fusion and advanced materials through climate and migration, to drug discovery and the sharp end of clinical decision making in personalised medicine — to run on current multi-petascale computers and emerging exascale environments with high fidelity such that their output is “actionable”. That is, the calculations and simulations are certifiable as validated (V), verified (V) and equipped with uncertainty quantification (UQ) by tight error bars such that they may be relied upon for making important decisions in all the domains of concern. The central deliverable will be an open source toolkit for multiscale VVUQ based on generic multiscale VV and UQ primitives, to be released in stages over the lifetime of this project, fully tested and evaluated in emerging exascale environments, actively promoted over the lifetime of this project, and made widely available in European HPC centres.

Past projects:

    • GreenVideo: The aim of this FUI project was to study and develop mechanisms for reducing energy consumption of image/video creation, transformation, broadcast and rendering.
    • APOS-EU: “Application Performance Optimisation and Scalability” (2011-2013). The APOS project has investigated technologies and develop tools for the software challenges encountered by computational scientists in the face of new trends in high-performance computing architecture development.
    • COMPA: “Conception Orientée Modèle de calcul pour multi‐Processeurs Adaptables” (“Model Oriented Design of Embedded and Adaptive Multiprocessor”). The aim of the ANR COMPA project was to propose a methodology and a design framework for running applications specified based on the dataflow process network model on a heterogeneous multi-core platform for embedded systems.

During my Ph.D., I took part in several projects especially in the following ones:

    • ROMA: “Reconfigurable Operators for Multimedia Applications” (2007-2010) supported by ANR Architectures du Futur.
    • SoCLib: Open platform for virtual prototyping of multi-processors system on chip (MP-SoC). The project started as an ANR-founded project. It is now maintained at LIP6.
