Dassault Aviation uses bullx to boost its computer simulation

Dassault Aviation has chosen bullx: a potent illustration of Bull's high level of expertise in High-Performance Computing (HPC) for very hi-tech industrial environments

Paris, November  23, 2010 -

A leading player in the civil and military aerospace industry, Dassault Aviation has chosen to extend its computing environment with two blade-based bullx supercomputers, developed by Bull.

A modular, scalable, secure and environmentally friendly

The constant drive for more and more precise simulation of physical phenomena demands increasingly sophisticated computer modeling of aircraft and associated components. The requirement for high performance in all areas, demands for security under any conditions, and the need to drastically cut energy footprints, means more and more complex multi-physical and multi-scale phenomena have to be taken into account. Nowadays, modeling an aircraft's structure involves handling several million points: so the demand for computing power is constantly growing.

Dassault Aviation - which is recognized as a leading user of digital technology and a supplier of some of the best performing aircraft in the world - has its own specialist High-Performance Computing unit, which the Group is aiming to upgrade so that it can excel in the design and development of the aircraft of the future.

As Alain Samblat, Head of the HPC environment at Dassault Aviation, explained: "We were looking for a supercomputer that was not only easy to integrate within our existing environment, but also modular and scalable, from several Teraflops to several tens of Teraflops capacity, and also that came with a level of warranty and maintenance in line with the security regulations we need to protect our data, at the same time as respecting environmental constraints."

Dassault Aviation has used Bull supercomputers since 2003, and has now chosen bullx, the Extreme Computing platform that meets all these criteria. Thanks to the culture of close cooperation that exists between Dassault Aviation and Bull teams, it was possible to configure the new bullx supercomputer and optimize it specifically for the main user applications, so meeting the most demanding operational requirements as soon as it was brought into service.

Major improvements in processing capacity

As well as outstanding computing performance, the operating capacity improvements delivered by bullx have fully met the targets set by Dassault Aviation. Because the system enables a rapid production start-up, simplifies hardware management and offers improved reliability, bullx meets the customer's demands for a professional, automated approach to scientific computing. "Integrating [bullx] into our environment and in our processing lifecycles has presented absolutely no difficulties. The performance we expected from our user applications has been achieved. The bullx supercomputer provides the ease of use and robustness that our engineers have a right to expect from a tool they use to carry out their everyday work," continued Alain Samblat.

Bull supercomputers currently account for some 60% of the total resources allocated by Dassault Aviation to High-Performance Computing in the area of electro-magnetic research.

Pascal Barbolosi, Vice President of Bull's Extreme Computing division, explained: "This new project clearly demonstrates Bull's ability to meet the demands of even the most sophisticated scientific computing environments, especially in terms of performance and reliability. Our teams are used to solving the most complex set of requirements, very rapidly, by combining the most powerful bullx servers with our Open Source-based software environment, to build supercomputers that are as powerful as they are reliable. That is why Bull stands head and shoulders above the rest in this highly competitive market."

Thanks to Bull - with whom it has established a genuine partnership around High-Performance Computing solutions - Dassault Aviation can now continuously upgrade its computing resources and optimize design processes as its business demands.
