Section: Other Grants and Activities
ANR WP : ANR White Program
ANR WP AutoChem Project
This project aims at investigating and exploring an unconventional approach, based on chemical computing, to program complex computing infrastructures, such as Grids and real-time deeply-embedded systems. It is a 3-year project which started in December 2007.
ANR CI : ANR Program on High-Performance Computing and Simulation
ANR CI DISC Project
It aims at studying and promoting a new paradigm for programming non-embarrassingly parallel scientific computing applications on distributed, heterogeneous, computing platforms. The DISC project concentrates its activities on numerical kernels and related issues that are of interest to a large variety of application contexts. It is a 3-year project which started in January 2006.
ANR CI LEGO Project
The aim of this project is to provide algorithmic and software solutions for large-scale architectures, focusing on performance issues. The software component approach provides a flexible programming model where resource management issues and performance optimizations are handled by the implementation. The project addresses topics in programming models, communication models, and scheduling. The results are validated on three applications: an ocean-atmosphere numerical simulation, a cosmology simulation, and a sparse-matrix solver. It is a 3-year project which started in January 2006. Project site: http://graal.ens-lyon.fr/LEGO/ .
ANR CI NUMASIS Project
It deals with recent NUMA multiprocessor machines with a deep hierarchy. In order to efficiently exploit it, the project aims at evaluating the features of current systems, at proposing and implementing new mechanisms for process, data and communication management. The target applications come from the seismology field that appear representative of current needs in scientific computing. It is a 3-year project which started in January 2006. Project site: http://numasis.gforge.inria.fr/ .
ANR MD : ANR Program on Data Masses and Ambient Knowledge
ANR MD RESPIRE Project
The RESPIRE Project of the ANR MD program aims at providing a peer-to-peer (P2P) environment for advanced data management applications. It gathers research teams from the “databases” area and from the “distributed systems” area, The RESPIRE Project is based on the JXTA infrastructure which provides a complete abstraction from the underlying P2P network organization (DHT, flooding, super-peer). The main actions that will be developed in the project are resource access and sharing, managing logical cluster, handling replication and automated deployment of the environment. The project started in January 2006 for 3 years. Gabriel Antoniu is the local correspondent of RESPIRE for the Paris Project-Team. Project site: http://respire.lip6.fr/ .
ANR SI : ANR Program on Security and Informatics
ANR SI SafeScale
The SafeScale Project is concerned with security and safety in global ambient computing systems, e.g., computational grids. We have used our adaptive techniques (e.g., Dynaco ) to implement application reactions to use-case attacks on an experiment on Grid'5000 . We have connected Dynaco to the Kaapi task execution environment to study adaptation with work-stealing.
The Paris project-team coordinated in 2008 a follow-up proposal to the Grid'5000 project of the ACI GRID. This proposal aims at the construction of a scientific instrument for experiments on large-scale parallel and distributed systems, building on the Grid'5000 platform. This proposal was accepted and officially started June 1st. It structures INRIA's leadership role as the institute is present in 8 if the 9 Grid'5000 sites distributed across France.
Thierry Priol is the director of this ADT, Franck Cappello the scientific director, Frédéric Desprez the deputy scientific director and David Margery the technical director. An executive committee, where each of the 10 project-teams supporting Grid'5000 in the 8 research centers is represented, meets every month. It gives recommendations to the directors on scientific animation, access policy to the instrument as well as for the hardware and software development according to the resources devoted to this ADT. Yvon Jegou represents the Paris project-team in this executive committee.
The technical team is now composed of 12 engineers, of which 3 are from the Paris project-team (David Margery, Pascal Morillon, Cyril Rohr). This technical team is structured in a sysadmin team, managing the instrument, and a developpment team building the tools to build, execute and analyze experiments.
In 2008, ALADDIN-G5K has enabled the coordinated acquisition of hardware on 2 sites, Rennes and Nancy, therefore reducing unwanted hardware heterogeneity. Moreover, it has enabled the transformation of a team of local system administrators loosely coordinated into a coherent team of engineers competent on all sites composing Grid'5000 with a clear leadership. More than 600 account are open, leading to a great number of experiments and publications on the topic of large scale parallel and distributed systems.
30 project-teams not including in the 10 mentioned above are using or have shown interest in using such an instrument.
ANR TLOG : ANR Program on Software Technologies
ANR TLOG NeuroLog Project
Participant : Yvon Jégou.
The NeuroLog consortium ( Software technologies for integration of process, data and knowledge in medical imaging ) is targeting software technologies in medical domains for large scale management of data, knowledge and computation: management and access of partly structured data, heterogeneous and distributed in an open environment; access control and protection of private medical data; control of workflows implied in complex computing process on grid infrastructures; extraction and quantification of relevant parameters for different pathologies.
