National Initiatives

PIA

ELCI

The ELCI project (Software Environment for HPC) aims to develop a new generation of software stack for supercomputers, numerical solvers, runtime and programming development environments for HPC simulation. The ELCI project also aims to validate this software stack by showing its capacity to offer improved scalability, resilience, security, modularity and abstraction on real applications. The coordinator is Bull, and the different partners are CEA, Inria, SAFRAN, CERFACS, CNRS CORIA, CENAERO, ONERA, UVSQ, Kitware and AlgoTech.

ANR

ANR SOLHAR

(http://solhar.gforge.inria.fr/doku.php?id=start).

  • ANR MONU 2013 Program, 2013 - 2017 (36 months extended )

  • Identification: ANR-13-MONU-0007

  • Coordinator: Inria Bordeaux/LaBRI

  • Other partners: CNRS-IRIT, Inria-LIP Lyon, CEA/CESTA, EADS-IW

  • Abstract: This project aims at studying and designing algorithms and parallel programming models for implementing direct methods for the solution of sparse linear systems on emerging computers equipped with accelerators. The ultimate aim of this project is to achieve the implementation of a software package providing a solver based on direct methods for sparse linear systems of equations. Several attempts have been made to accomplish the porting of these methods on such architectures; the proposed approaches are mostly based on a simple offloading of some computational tasks (the coarsest grained ones) to the accelerators and rely on fine hand-tuning of the code and accurate performance modeling to achieve efficiency. This project proposes an innovative approach which relies on the efficiency and portability of runtime systems, such as the StarPU tool developed in the runtime team (Bordeaux). Although the SOLHAR project will focus on heterogeneous computers equipped with GPUs due to their wide availability and affordable cost, the research accomplished on algorithms, methods and programming models will be readily applicable to other accelerator devices such as ClearSpeed boards or Cell processors.

ANR Songs

Simulation of next generation systems (http://infra-songs.gforge.inria.fr/).

  • ANR INFRA 2011, 01/2012 - 12/2015 (48 months)

  • Identification: ANR-11INFR01306

  • Coordinator: Martin Quinson (Inria Nancy)

  • Other partners: Inria Nancy, Inria Rhône-Alpes, IN2P3, LSIIT, Inria Rennes, I3S.

  • Abstract: The goal of the SONGS project is to extend the applicability of the SimGrid simulation framework from Grids and Peer-to-Peer systems to Clouds and High Performance Computation systems. Each type of large-scale computing system will be addressed through a set of use cases and lead by researchers recognized as experts in this area.

ADT - Inria Technological Development Actions

ADT SwLoc

(http://swloc.gforge.inria.fr/)

Participants : Raymond Namyst, Pierre-André Wacrenier, Andra Hugo, Brice Goglin, Corentin Salingue.

  • Inria ADT Campaign 2017, 10/2017 - 9/2019 (24 months)

  • Coordinator: Raymond Namyst

  • Abstract: The Inria action ADT SwLoc has the aim to develop a new library allowing dynamic flexible partitioning of computing resources in order to execute parallel regions.

IPL - Inria Project Lab

C2S@Exa - Computer and Computational Sciences at Exascale

Participant : Olivier Aumage.

  • Inria IPL 2013 - 2017 (48 months)

  • Coordinator: Stéphane Lantéri (team Nachos, Inria Sophia)

Since January 2013, the team is participating to the C2S@Exa http://www-sop.inria.fr/c2s_at_exa Inria Project Lab (IPL). This national initiative aims at the development of numerical modeling methodologies that fully exploit the processing capabilities of modern massively parallel architectures in the context of a number of selected applications related to important scientific and technological challenges for the quality and the security of life in our society. This collaborative effort involves computer scientists that are experts of programming models, environments and tools for harnessing massively parallel systems, algorithmists that propose algorithms and contribute to generic libraries and core solvers in order to take benefit from all the parallelism levels with the main goal of optimal scaling on very large numbers of computing entities and, numerical mathematicians that are studying numerical schemes and scalable solvers for systems of partial differential equations in view of the simulation of very large-scale problems.

HAC-SPECIS - High-performance Application and Computers, Studying PErformance and Correctness In Simulation

Participants : Samuel Thibault, Luka Stanisic, Emmanuelle Saillard.

  • Inria IPL 2016 - 2020 (48 months)

  • Coordinator: Arnaud Legrand (team Polaris, Inria Rhône Alpes)

Since June 2016, the team is participating to the HAC-SPECIS http://hacspecis.gforge.inria.fr/ Inria Project Lab (IPL). This national initiative aims at answering methodological needs of HPC application and runtime developers and allowing to study real HPC systems both from the correctness and performance point of view. To this end, it gathers experts from the HPC, formal verification and performance evaluation community.
