International Initiatives

Inria International Labs

The University of Illinois at Urbana-Champaign, Inria, the French national computer science institute, Argonne National Laboratory, Barcelona Supercomputing Center, Jülich Supercomputing Centre and the Riken Advanced Institute for Computational Science formed the Joint Laboratory on Extreme Scale Computing, a follow-up of the Inria-Illinois Joint Laboratory for Petascale Computing. The Joint Laboratory is based at Illinois and includes researchers from Inria, and the National Center for Supercomputing Applications, ANL, BSC and JSC. It focuses on software challenges found in extreme scale high-performance computers.

Research areas include:

• Scientific applications (big compute and big data) that are the drivers of the research in the other topics of the joint-laboratory.

• Modeling and optimizing numerical libraries, which are at the heart of many scientific applications.

• Novel programming models and runtime systems, which allow scientific applications to be updated or reimagined to take full advantage of extreme-scale supercomputers.

• Resilience and Fault-tolerance research, which reduces the negative impact when processors, disk drives, or memory fail in supercomputers that have tens or hundreds of thousands of those components.

• I/O and visualization, which are important part of parallel execution for numerical silulations and data analytics

• HPC Clouds, that may execute a portion of the HPC workload in the near future.

Several members of the ROMA team are involved in the JLESC joint lab through their research on resilience. Yves Robert is the Inria executive director of JLESC.

Inria Associate Teams not involved in an Inria International Labs

• Laure Gonnord and Maroua Maalej are involved in the PROSPIEL Associate Team (Inria/ Brasil, https://team.inria.fr/alf/prospiel/ ). The PROSPIEL project aims at optimizing parallel applications for high performance on new throughput-oriented architectures: GPUs and many-core processors. Specifically, Laure Gonnord and Maroua Maalej are in charge of designing static analyses for GPUs. In Feb.-Apr. 2016, ROMA will host one student coming from the Brasilian team.
