Currently, an IBM supercomputer based on the Power6 is in operation at the German Climate Computing Center in Hamburg.By 2016, the existing system will be replaced by a Bull Blade computer with hot water cooling. The new calculator will deliver a performance of 3 petaflop / s and deliver 45 petabytes of storage capacity. Source: DKRZ
The German Climate Center (DKRZ) gets a new high-performance computer. By 2016, the computer based on Bullx B700 DLC Blades should be able to perform 3 quadrillion calculationsper second (3 petaflop / s). Thus, the calculator could theoretically process 10 million DVDs per second. As memory, the calculator will have a capacity of 45 petabytes.
The DKRZ wants to replace according to own data in the next two years with the new computer the existing high performance computer based on IBM Power6.
The aim of the calculator is to improve climate models and, of course, the question of how the climate will evolve in the future. The scientists use computer-aided climate models.
"Only with high-performance computers adapted to the latest technology can improved climate predictions be made. With the Bull calculator, we hope to gain new insights, especially in predicting cloud formation ", emphasizes Prof. Dr. med. Jochem Marotzke, Director at the Max Planck Institute for Meteorology, main user of the DKRZ's social facilities.
Also for the efficient input and output and processing of large amounts of data (big data) the computer should be used. The higher performance also allows for better model resolution, giving science new opportunities to model even small scale processes in global simulations.
According to DKRZ, the new computer will improve the performance of the currently used system by a factor of 20. As of 2016, a total of 60,000 processor cores will be responsible for the computing power in around 60 racks. The Bullx B700 Blade is currently based on Intel Xeon. In addition, the blades also supported co-processors from Intel, codenamed Phi, and Nvidia Tesla GPUs. In addition to Intel, which will contribute Haswell and Broadwell processors to the project, the DKRZ also mentions Xyratex for storage systems and Mellanox for high-speed networking as another technology partner.

At 45 petabytes, the future climate computer has one of the largest storage systems. With 3 petabytes, the climate calculator would currently be on Top500.org among the five fastest supercomputer Germany.

Thanks to the concept of Direct Liquid Cooling , a hot water cooling system , the Bull Blade system can achieve high energy efficiency despite its high performance. The manufacturer promises a PUE value of 1.2.
In addition, Bull also relies on a cooperation project with the TU Dresden in the Bullx B700. The name of the project is: HDEEM, High Definition Energy Efficiency Monitoring. The goal of this cooperation is the development of HPC algorithms that are designed to further reduce power consumption.
The project is estimated to cost € 41 million, two-thirds of which comes from the Federal Ministry of Education and Research and one third from the Helmholtz Association of German Research Centers. At the 1987 founded DKRZ are currently about 70 employees.
