The BMW Sauber F1 Team has a new super brain. Albert2, presented on Thursday to international media representatives in Hinwil, is Europe’s fastest machine used in industry according to the current Top-500 list.

Albert2 is based on Intel processors and employed by the team for computational fluid dynamics (CFD). On average, it is about three times faster than its predecessor.

BMW Motorsport Director Mario Theissen: “Aerodynamics has a crucial influence on the performance of modern Formula 1 cars, with experimental work in the wind tunnel and computational fluid dynamics complementing each other. The launch of Albert2 means a decisive reinforcement of our CFD capacity. Unlike other teams, we are not planning to build a second wind tunnel but will continue to bank on the consistently expanding potential in this area. For the new season, we have set the goal of further reducing the gap to the top. Our new Supercomputer based on Intel technology is an important tool supporting us in this effort.”

“The powerful Dual-Core Xeon processors perfectly match the high demand on computing power of the BMW Sauber F1 Team. The cluster based on these processors is one of the fastest in the world running computational fluid dynamic applications,“ said Christian Morales, Vice President & General Manager of Intel Europe, Middle East and Africa. “With the move to Multi-Core we are able to meet the future demand on computing power of the BMW Sauber F1 Team for computational fluid dynamics.”

Albert2 is based on Intel technology. It has 256 nodes with two Intel Xeon 5160 processors each, and each of these has two cores. This results in a total of 1024 cores. The capacity of the main memory is 2,048 Gbyte, the maximum computing power is 12,288 GFlops. To illustrate the point for non-computer-experts, this means that Albert2 is capable of performing 12,288,000,000,000 floating-point arithmetic operations per second. To equal this computing power, all the inhabitants of the city of Munich (1.3 million) would have to multiply two eight-digit numbers every three and a half seconds for an entire year.

According to the criteria defined for acceptance in the Top-500 list of Supercomputers, this data makes Albert2 5.5 times faster than its predecessor, Albert. In the field, though – as with any computer – the software used plays a crucial part when it comes to speed. But even when running the complex programs for CFD calculations the increase is immense: when using the Fluent application, the average performance improvement amounts to a factor of three.

The architecture of the Supercomputer was developed by the Swiss company DALCO. A key objective was the achievement of high levels of efficiency as well as very good scalability, meaning that operations can be split among many processors without any significant loss of performance.
