许多高性能CPU采用多核体系结构，具有中等时钟频率和广泛的指令问题，包括SIMD扩展，以在保持实际功耗的同时实现高性能。随着对超级计算机性能的需求增长快于CPU性能的改善速度，高端超级计算机的核心总数大幅增加。高效地处理大量核心是超级计算机设计中的一个关键方面。从成本和可用性的角度来看，建造一台功耗更低、可靠性更高的超级计算机也很重要。
Many high-performance CPUs employ a multicore architecture with a moderate clock frequency and wide instruction issue, including SIMD extensions, to achieve high performance while retaining a practical power consumption. As demand for supercomputer performance grows faster than the rate that improvements are made to CPU performance, the total number of cores of high-end supercomputers has increased tremendously. Efficient handling of large numbers of cores is a key aspect in the design of supercomputers. Building a supercomputer with lower power consumption and significant reliability is also important from the viewpoints of cost and availability.
