一 | （via Phoronix）本周早些时候，AMD 发布了 GNU 编译器集合（GCC）的基础支持代码，扩展了对 Zen 4 微架构的支持。相信随着时间的推移，该公司还会带来与 Znver4 相关的更多改进。更新后的 Zenver4 基础启用补丁，与 Zenver3 基本相同、但添加了对 AVX-512 新指令集的支持 —— 即 AVX512F、AVX512DQ、AVX512IFMA、AVX512CD、AVX512BW、AVX512VL、AVX512BF16、AVX512VBMI、AVX512VBMI2、GFNI、 AVX512VNNI、AVX512BITALG 和 AVX512VPOPCNTDQ。（来自：LKML）除了 AVX-512，Zen 4 相较于 Zen 3 的架构差异并不大。 Rome, Oct 12 (UNI) A Boeing 747-400 Dreamlifter aircraft lost one of its wheels soon after take off from Taranto in Italy.
A clip of the mishap, which was snapped on Tuesday close to the airstrip in Taranto, shows the part fly through the air in a blaze before disappearing from the shot, the Sun reported.
Black smoke can be seen coming from the undercarriage of the aircraft as the wheel comes loose. It then hit the ground and bouncing along below the plane.
The missing part was reportedly found outside the confines of the airport, some way from where it fell off.
Amazingly, the jet carried on its take-off without any visible effects. The plane -- a super-sized cargo version of a Jumbo Jet -- landed safely at its destination in North Carolina in the US.
UNI MR。不过相较于消费级市场，这项特性显然更适用于新一代 EPYC（霄龙）Genoa 服务器平台的使用场景。当然，对于要求不高的中小型企业，依然可借助支持 AVX-512 的 Ryzen 7000 系列处理器，来适当降低业务系统的构建成本。
