该论文介绍了基于Intel 14nm三栅极CMOS工艺的SkyLake-SP（SKX）至强服务器处理器，解决了高性能计算中核心数量、缓存层次和内存带宽的平衡问题。通过28核配置、每核1MB L2缓存和1.375MB非独占L3缓存，以及6通道DDR4内存支持，实现了可扩展的性能提升。
Kalapi Royneogi, Nagmohan Satti, Rizwan Qureshi, Wei Chen, Tom Wang, Hubert Hsieh, Sujal Vora, Eddie Wang Intel, Santa Clara, CA SkyLake-SP (Scalable Performance), code name SKX, is the next generation Xeon® server processor fabricated on the Intel® 14nm tri-gate CMOS technology with 11-metal layers [1,2]. The SKX processor family has three core-count configurations. Each SKX core is accompanied by 1MB of dedicated L2 (2nd level cache) and 1.375MB of non-exclusive L3 (3rd level cache). At its maximum configuration of 28 cores, the SKX processor supports 6 DDR4 channels (2666MT/s), 3×20-lanes UPI processor-to-processor links (10.4GT/s) and x48+4 PCIE links (8GT/s). SKX supports per-core power-performance optimization enabled by on-die integrated voltage regulators (FIVR) [3, 4]. A new 2-dimensional synchronous on-die MESH fabric interconnects all the on-die components. Fig. 2.1.1 shows the overall architecture of the SKX processor.
