ANR Blanche: Stochagrid (Scheduling algorithms and stochastic performance models for workflow applications on dynamic Grid platforms), 3 years, ANR-06-BLAN60192-01, 2007-2010

In the third and final year of the project (2010), we have pursued the investigation of timed Petri nets to model the mapping of workflows with stage replication, in collaboration with Bruno Gaujal (LIG Grenoble).

Also, we have investigated several multi-criteria algorithms and heuristics for the problem of mapping pipelined applications, consisting of a linear chain of stages executed in a pipeline way, onto heterogeneous platforms. This work was conducted by the post-doctoral student hired on the project, Hinde Bouziane, and the first paper published on this work received the best paper award.

The project is entirely conducted within the GRAAL team by A. Benoit and Y. Robert.

ANR grant Gwendia ANR-06-MDCA-009 (Grid Workflow Efficient Enactment for Data Intensive Applications), 3 years, 2007-2010

The objective of the Gwendia(http://gwendia.polytech.unice.fr/doku.php ) project is to design and develop workflow management systems for applications involving large amounts of data. It is a multidisciplinary project involving researchers in computer science (including GRAAL) and in life science (medical imaging and drug discovery). Our work consists in designing algorithms for the management of several workflows in distributed and heterogeneous platforms and to validate them within Diet over the Grid'5000 platform.

ANR grant SPADES, 3 years, 08-ANR-SEGI-025, 2009-2012

Today's emergence of Petascale architectures and evolutions of both research grids and computational grids increase a lot the number of potential resources. However, existing infrastructures and access rules do not allow to fully take advantage of these resources. One key idea of the SPADES project is to propose a non-intrusive but highly dynamic environment able to take advantage of the available resources without disturbing their native use. In other words, the SPADES vision is to adapt the desktop grid paradigm by replacing users at the edge of the Internet by volatile resources. These volatile resources are in fact submitted via batch schedulers to reservation mechanisms which are limited in time or susceptible to preemption (best-effort mode).

One of the priorities of SPADES is to support platforms at a very large scale. Petascale environments are therefore particularly considered. Nevertheless, these next-generation architectures still suffer from a lack of expertise for an accurate and relevant use. One of the SPADES goal is to show how to take advantage of the power of such architectures. Another challenge of SPADES is to provide a software solution for a service discovery system able to face a highly dynamic platform. This system will be deployed over volatile nodes and thus must tolerate failures. SPADES will propose solutions for the management of distributed schedulers in Desktop Computing environments, coping with a co-scheduling framework.

ANR grant: COOP (Multi Level Cooperative Resource Management), 3 years, ANR-09-COSI-001-01, 2009-2012

The main goals of this project are to set up such a cooperation as general as possible with respect to programming models and resource management systems and to develop algorithms for efficient resource selection. In particular, the project targets the SALOME platform and GRID-TLSE expert-site (http://gridtlse.org/ ) as an example of programming models, and Marcel/PadicoTM, DIET and XtreemOS as examples of multithread scheduler/communication manager, grid middleware and distributed operating systems.

The project is led by Christian Pérez.

ANR JCJC: Clouds@Home (Cloud Computing over Unreliable, Shared Resources), 4 years, ANR-09-JCJC-0056-01, 2009-2012

Recently, a new vision of cloud computing has emerged where the complexity of an IT infrastructure is completely hidden from its users. At the same time, cloud computing platforms provide massive scalability, 99.999% reliability, and speedy performance at relatively low costs for complex applications and services. This project, lead by D. Kondo from INRIA MESCAL investigates the use of cloud computing for large-scale and demanding applications and services over unreliable resources. In particular, we target volunteered resources distributed over the Internet. In this project, G. Fedak leads the Data management task (WP3).

ANR ARPEGE MapReduce (Scalable data management for Map-Reduce-based data-intensive applications on cloud and hybrid infras tructures), 4 years, ANR-09-JCJC-0056-01, 2010-2013

MapReduce is a parallel programming paradigm successfully used by large Internet service providers to perform computations on massive amounts of data. After being strongly promoted by Google, it has also been implemented by the open source community through the Hadoop project, maintained by the Apache Foundation and supported by Yahoo! and even by Google itself. This model is currently getting more and more popular as a solution for rapid implementation of distributed data-intensive applications. The key strength of the Map-Reduce model is its inherently high degree of potential parallelism.

In this project, the GRAAL team participates to several work packages which address key issues such as efficient scheduling of several MR applications, integration using components on large infrastructures, security and dependability, MapReduce for Desktop Grid.

ANR Blanche: RESCUE (Resilience for exascale scientific computing), 4 years, ANR-2010-BLAN-0301-01, 2010-2014

The emergence of exascale computers will enable to solve new scientific challenges. However, the scientific applications deployed on such machines comprising up to millions of cores will have to cope with numerous failures: it is forecasted that with the current techniques, the mean time between two consecutive failures will be shorter than the time needed to checkpoint an application using the whole platform. The main objective of the RESCUE project is to develop new algorithm techniques and new software to solve the fault-tolerance problem on exascale machines.

The RESCUE project is led by Y. Robert and involves three INRIA teams: Grand-Large, HiePACS and GRAAL (A. Benoit, L. Marchal, F. Vivien).

ADT-MUMPS, 3 years, 2009-2012

ADT-MUMPS is an action of technological development funded by Inria . This project gives support for 24 men x months of young engineer (“ingénieur jeune diplômé”). A permanent engineer from INRIA/SED also works on the project (Maurice Brémond, 30 % on the project). One goal of the project is to improve daily work of Mumps developers by improving the software engineering aspects, by developing non-regression tests and drivers to experiment the package. This project is in collaboration with ENSEEIHT-IRIT.

ADT ALADDIN

ALADDIN is an Inria action of technological development for “A LArge-scale DIstributed and Deployable INfrastructure” which aim is to manage the Grid'5000 experimental platform. Frédéric Desprez is leading this project (with David Margery from Rennes as the Technical Director).

ADT BitDew, 2 years, 2010-2012

ADT BitDew is an INRIA support action of technological development for the BitDew middleware. Objectives are several fold : i/ provide documentation and education material for end-users, ii/ improve software quality and support, iii/ develop new features allowing the management of Cloud and Grid resources. The ADT BitDew, leaded by G. Fedak, allows to recruit a young engineer for 24 months.

HEMERA Large Wingspan Inria Project

Hemera deals with the scientific animation of the Grid'5000 community. It aims at making progress in the understanding and management of large scale infrastructure by leveraging competences distributed in various French teams. Hemera contains several scientific challenges and working groups. Christian Pérez is leading the project that involves more than 20 teams located in 9 cities of France.

Action Interfaces Recherche en grille – Grilles de production. Institut des Grilles du CNRS – Action Aladdin INRIA

This action addresses economical issues concerning green-ness in scientific and production grids. Different issues are addressed like the confrontation of energy models in place in experimental grids versus the operational realities in production grids, the study of new energy prediction models related to real measures of energy consumption in production grids, and the design of energy aware scheduling heuristics.

Y. Caniou participates to this action.
