The CEA Computing Center Selects Scality for HPC Storage

Scality, the leader in software-based storage for the information age, has been selected by the French Alternative Energies and Atomic Energy Commission (CEA) to power its HPC storage needs at the Scientific Computing Complex of the CEA’s Military Applications Division (DAM). Scality and CEA will work together to advance their ongoing research and development projects, as well as CEA’s own HPC contributions, including the “Lustre”, “RobinHood” and “Ganesha” software solutions, and to collaborate on an exascale project environment.

10 years of seismic signals analysed in a few hours – CEA/DIF is tackling Big Data challenges

Two CEA divisions (resp. in Computer Science* and Earth Sciences**) from CEA/DIF developed a demonstrator enabling the efficient exploitation of 10 years of seismic signals (20 TB of data). This action has been supported by DataScale project, funded by the Digital Economy Development plan of the French government ‘Programme d’Investissements d’Avenir’. The objective was to design and develop a processing chain able to detect earthquakes in large volumes of geophysical data, so as to spot events that were previously unnoticed – by comparing the continuous flow of recordings with past earthquakes already identified. The unprecedented scale of processing reached here is a real breakthrough. With technical assistance of DSSI and CCRT*** application support, the data processing workflow has been redesigned to handle and process millions of files with a reasonable time-to-solution (a few hours). This workflow has then been validated and tested on 32 000 cores of GENCI's CURIE supercomputer. The technical innovation relies on an efficient structuring and management of distributed data, together with a hierarchical dispatching and scheduling of processing tasks on the available compute cores. This experiment has revealed, on a 10 year timescale, the seismic activity of several volcanoes. Thanks to DataScale, the proven feasibility of this massive data processing is paving the way towards a revolution in the exploitation of seismic monitoring networks data.

First "Robinhood User Group"

Robinhood Policy Engine is a tool developed by CEA to manage contents of large HPC file systems. Available as open source software since 2009, the user community of this software keeps growing and now represents a significant part of HPC sites, in particular those using Lustre parallel file systems. Also, this software is now integrated by main HPC vendors as part of their storage solutions.
In this context, CEA organized last September 21st 2015 the first Robinhood User Group at Marriott Hotel Champs-Elysees Paris, co-located with LAD. The goal of this event is to bring together actors involved in the project: users, contributors, integrators, and support teams.
This first edition was a success with an attendance over expectations. In particular, main storage vendors were represented at this meeting: Atos/Bull, Cray, DDN, Intel, Seagate, SGI.
Attendees found this meeting useful and necessary to increase the level of information about the software, share best practices, discuss incoming evolutions and future needs. They wish this event will take place the next years.

CEA / DIF strengthens its participation in the "EU Code of Conduct for Data Centre" for the energy optimization of the TGCC.

The European Code of Conduct for data centers (CoC) is a process developed by the "Joint Research Center" of the European Commission. It defines and lays down rules for good practices in energy efficiency for data centers or data processing.

This year CEA/DIF actively participated to the CoC, in partnership with the Joint Research Center (JRC), scientific service of the European Commission, adding its TGCC facility as a Participant member of the CoC.

In California, the inextinguishable "thirst" of "data centers"

The website of public radio RFI is investigating the optimization of energy and water consumption of computing and digital data storage centers. "CEA researchers and  engineers have found a way to reduce by 30% the consumption of water in their cooling system, between 2000, setup of their first computing and data center, and 2010, when the second facility was opened." says rfi.fr.
