计算机在研究和工业中是必不可少的，但它们也是全球电力消耗的重要贡献者。Loewe-CSC超级计算机通过为高性能和通用计算设置环境兼容性以及能源和冷却效率的新标准来解决这一问题。设计一个全面节能的计算中心需要在多个领域进行改进。托管低损耗计算中心以低于计算机功率8%的冷却开销运行。通用图形处理单元提供比标准处理器更高的计算性能功耗比。均衡的硬件配置可确保用户在使用优化的应用程序时可以使用大部分计算能力。巧妙的算法使用户能够充分利用计算潜力，并避免在处理器空闲时浪费电力，这往往是编程效率低下的原因。通过使用商用服务器，Loewe-CSC在LINPACK基准测试运行期间以740MFlops/W的速度运行，在2010年11月的Green500榜单中排名第8位。这些创新为实现经济高效、环境友好的亿级计算和IT运营迈出了根本的一步。
Computers are essential in research and industry, but they are also significant contributors to the worldwide power consumption. The LOEWE-CSC supercomputer addresses this problem by setting new standards in environmental compatibility as well as energy and cooling efficiency for high-performance and general-purpose computing. Designing a pervasively energy efficient compute center requires improvements in multiple fields. The hosting low-loss compute-center operates at a cooling overhead below 8% of the computer power. General purpose graphics processing units provide more compute performance per watt than standard processors. A balanced hardware configuration ensures that most of the compute power is available to the user when he employs optimized applications. Clever algorithms enable the user to fully exploit the computational potential and avoids to waste power when the processors idles, which is often a cause of inefficient programming. The LOEWE-CSC operated at 740MFlops/W during a Linpack benchmark run, by using commodity servers and ranked place 8 in the Green500 list of November 2010. These innovations provide a fundamental step towards cost-effective, environment-friendly exascale computing and IT operation.
