National Initiatives

COOP ANR COSINUS Project (2009-2013)

Participants : Yvon Jégou, Christine Morin, Yann Radenac.

The COOP project (http://coop.gforge.inria.fr/ ) funded under the ANR COSINUS program relates to multi level cooperative resource management. The two main goals of this project are to set up a cooperation as general as possible with respect to programming models and resource management systems (RMS) and to develop algorithms for efficient resource selection. Experimentations were conducted in particular with the SALOME platform and TLSE as examples of programming environments and Marcel, DIET and XtreemOS as examples of RMS. Partners involved in the COOP project are the AVALON and RUNTIME Inria EPI, IRIT and EDF R&D. This project funds a research engineer (Yann Radenac). In 2013, we completed the design and implementation of the modifications needed in XtreemOS Grid distributed operating system in order to integrate the CooRM architecture defined by the Avalon Inria team to support dynamic applications.

MIHMES ANR Investissements d'Avenir (2012 - 2018)

Participants : Yvon Jégou, Christine Morin.

The MIMHES project (http://www.inra.fr/mihmes ) led by INRA/BioEpAR aims at producing scientific knowledge and methods for the management of endemic infectious animal diseases and veterinary public health risks. Myriads team will provide software tools to efficiently manage and ease the use of a distributed computing infrastructure for the execution of different simulation applications.

In 2013, we interacted with the INRA/BioEpAR research team in order to improve the initial software prototype and to make it ready for parallelisation. The code has been re-written in C++. In 2014, Inria is in charge of developing a parallel version of the code.

HEMERA Inria AEN (2010-2013)

Participants : Bogdan Florin Cornea, Yvon Jégou, Christine Morin, Anne-Cécile Orgerie.

The Myriads team is involved in the HEMERA large wingspan project funded by Inria (http://www.grid5000.fr/mediawiki/index.php/Hemera ). This project aims at demonstrating ambitious up-scaling techniques for large scale distributed computing by carrying out several dimensioning experiments on the Grid'5000 infrastructure, at animating the scientific community around Grid'5000 and at enlarging the Grid'5000 community by helping newcomers to make use of Grid'5000. Yvon Jégou is co-chair of the "Bring Grids Power to Internet-Users thanks to Virtualization Technologies" working group. Anne-Cécile Orgerie is involved in the "Energy" working group which is currently looking at making energy-aware experiments on Grid'5000 easier for the users. This project funds Bodgan Florin Cornea's postdoc.

Inria ADT Aladdin (2008-2013)

Participants : Yvon Jégou, David Margery, Pascal Morillon.

The Aladdin technological development action funded by Inria aims at the construction of a scientific instrument for experiments on large-scale parallel and distributed systems, building on the Grid'5000 platform (http://www.grid5000.fr ).

As governing body of Grid'5000, it was superseded by a national GIS (Scientific interest group) that was signed in 2012.

As the host of engineers contributed to Grid'5000's technical team by Inria , it finished operating in 2013. Two engineers of this technical team who are SED (The SED is the Inria Experimentation and Development Service.) members are still hosted in the Myriads team: David Margery, technical director and Pascal Morillon. Pascal Morillon is the chief engineer for all tasks automating Grid'5000 administration.

Inria ADT Snooze (2012-2014)

Participants : Eugen Feller, Yvon Jégou, David Margery, Christine Morin, Anne-Cécile Orgerie, Matthieu Simonin.

The Snooze technological development action funded by Inria aims at developing an IaaS cloud environment based on the Snooze virtual machine framework developed by the team (http://snooze.inria.fr ) and to make this new environment available to a wide community.

In 2013, we validated Snooze at large scale on the Grid'5000 testbed. A poster was presented at CCGRID 2013  [35] and the results of the study were awarded the second prize at CCGRID2013 scale challenge [26] . We introduced the Apache Casssandra system as database backend in Snooze. We have also started to refactor some parts of the code to enable the use of plugins. We implemented an EC2 interface and a web GUI. Puppet recipes were also released as well as a capistrano based deployment script for Grid'5000.

CNRS GDS EcoInfo

Participant : Anne-Cécile Orgerie.

The EcoInfo group deals with reducing environmental and societal impacts of Information and Communications Technologies from hardware to software aspects. This group aims at providing critical studies, lifecycle analyses and best practicies in order to improve the energy efficiency of printers, servers, data centers, and any ICT equipment in use in public research organizations.

CominLabs EPOC project (2013-2016)

Participants : Sabbir Hasan, Yunbo Li, Anne-Cécile Orgerie, Jean-Louis Pazat.

In this project, partners aim at focusing on energy-aware task execution from the hardware to application's components in the context of a mono-site data center (all resources are in the same physical location) which is connected to the regular electric Grid and to renewable energy sources (such as windmills or solar cells). In this context, we tackle three major challenges:

• Optimizing the energy consumption of distributed infrastructures and service compositions in the presence of ever more dynamic service applications and ever more stringent availability requirements for services.

• Designing a clever cloud's resource management which takes advantage of renewable energy availability to perform opportunistic tasks, then exploring the trade-off between energy saving and performance aspects in large-scale distributed systems.

• Investigating energy-aware optical ultra high-speed interconnection networks to exchange large volumes of data (VM memory and storage) over very short periods of time.

IRT B-Com

Participants : Yvon Jégou, Jean-Louis Pazat, Édouard Outin.

Yvon Jégou and Jean-Louis Pazat are at IRT B-Com (http://b-com.org/wp/ ) one day per week, Yvon Jégou since October 1^st and Jean-Louis Pazat since September 1^st. With Édouard Outin, B-com phd student, they contribute to the B-Com Indeed project which aims at developing a distributed cloud software stack with a high degree of adaptability.
