National Initiatives

Inria ADT GinFlow (2014-2016)

Participants : Christine Morin, Javier Rojas Balderrama, Matthieu Simonin, Cédric Tedeschi.

The GinFlow technological development action funded by Inria targets the development of a fully-operational workflow management system based on the HOCL-TS software prototype developed during the PhD thesis of Héctor Fernandez between 2009 and 2012. Also, it allows the integration of this software with the TIGRES workflow engine developed at the Lawrence Berkeley National Lab so as to make the workflows submitted using the TIGRES programming model run in a decentralized fashion.

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 2014, we refactored some parts of the code to enable the use of plugins. We also developed the Cloud Agnostic Checkpointing Service (CACS) service on top of Snooze to enable application recovery in the event of the failure of servers hosting virtual machines [31] .

HEMERA Inria AEN (2010-2014)

Participants : Bogdan Florin Cornea, Yvon Jégou, 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 funded Bodgan Florin Cornea's postdoc supervised by Anne-Cécile Orgerie and Laurent Lefèvre (Inria, LIP, Lyon).

Inria IPL CityLab (under submission) (2014-2018)

Participants : Roberto-Gioacchino Cascella, Christine Morin.

The Inria Project Lab (IPL) CityLab@Inria (informally started - see https://citylab.inria.fr ) studies ICT solutions toward smart cities that promote both social and environmental sustainability. A strong emphasis of the Lab is on the undertaking of a multi-disciplinary research program through the integration of relevant scientific and technology studies, from sensing up to analytics and advanced applications, so as to actually enact the foreseen smart city Systems of Systems. City-scale experiments of the proposed platforms and services are planned in cities in California and France, thereby learning lessons from diverse setups.

Myriads investigates advanced cloud solutions for the Future Internet, which are critical for the processing of urban data. It leverages its experience in cloud computing and Internet of services while expanding its research activities to the design and implementation of cloud services to support crowd-Xing applications and mobile social 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 2014, we interacted with the INRA/BioEpAR research team in order to improve the initial software prototype and to make it ready for parallelisation. A first parallel version of the code was delivered by Inria during summer 2014. This first version uses the OpenMP standard to exploit multiple processor cores of the same server. A speed-up approaching 20 has been observed on a 24-cores Dell server for a single run. A whole simulation necessitates multiple runs (a few hundreds) to reach precise results. During the next steps, the presence of these runs will be exploited both to increase the volume of the internal computations (increase the efficiency of multi-core computation) and to exploit multiple servers.

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 practices in order to improve the energy efficiency of printers, servers, data centers, and any ICT equipment in use in public research organizations.
