<define-tag pagetitle>New beowulf cluster at EDF (200 Tflops) based on Debian 6.0 Squeeze</define-tag>
<define-tag release_date>2011-07-29</define-tag>
#use wml::debian::news
#use wml::debian::translation-check translation="3355bd47177276c39803106c1d06de446e8f4592" original="french"
<p>Électricité de France S.A. is pleased to announce that its new supercomputer,
which is 200 Tflops and 43rd in the latest <a
href="http://www.top500.org/system/10804">TOP500 (June 2011)</a>, is based on
Debian Squeeze.</p>
<p>This supercomputer, called Ivanoe, is made of compute nodes, graphical nodes,
connexion servers and infrastructure servers. This represents 1454 IDataPlex
IBM Servers and 200 Tflops.</p>
<p>Compute nodes, graphical nodes and connexion servers are fully diskless and
bootstrap thanks to the <a href="$(HOME)/CD/live/"><q>Debian
Live Project</q></a>, but we still have servers
that are installed on disk thanks to <a href="https://fai-project.org/"><q>Fully Automatic Installation</q></a> which
are configured by <a href="https://projects.puppetlabs.com/projects/puppet"><q>Puppet</q></a>.</p>
<p>To achieve this installation EDF teams of engineers had to integrate several
proprietary software components in the Debian environment, more precisely the
General Parallel File System (GPFS) which is an IBM product and the Infiniband
QLogic driver which is used for the Infiniband network.</p>
<p>The system image has been generated based on the official Debian repository and
is made up of 900 packages. The packages installed match the requirements for
the EDF calculus software that is used by the company.</p>
<p>The teams of engineers that have worked on this project would like to thank
Stefano Zacchiroli for his help and his availability, thank all Debian
Developers for the quality of their contributions to the community, and
finally, thank IBM, the manufacturer, for helping us support Debian on their
hardware.</p>
<p>EDF has chosen an homogenisation strategy for its scientific computing based on
a common stack of software, namely Debian. An internal team of engineers is in
charge of developing and adapting the distribution to match the specific needs
of scientific computing. Debian at EDF represents 1050 workstations dedicated
to scientific usage and 9 beowulf clusters which represent 2132 compute nodes.</p>
<h2>About EDF Group</h2>
<p>EDF Group, one of the leaders in the energy market in Europe, is a
comprehensive energy service provider with operations in every sector,
including energy generation, transport, distribution, trading and sales. The
Group is the leading electricity producer in Europe. EDF's transport and
distribution subsidiaries operate 1,285,000 km of low and medium voltage
overhead and underground electricity lines and around 100,000 km of high and
very high voltage networks. The Group is involved in supplying energy and
services to more than 28 million customers in France.</p>
<h2>About Debian</h2>
<p>The Debian Project was founded in 1993 by Ian Murdock to be a truly free
community project. Since then the project has grown to be one of the largest
and most influential open source projects. Thousands of volunteers from all
over the world work together to create and maintain Debian software. Available
in 70 languages, and supporting a huge range of computer types, Debian calls
itself the <q>universal operating system</q>.</p>
