A |     英特尔提供的新编译器更新将协助为Sierra Forest CPU中看到的指令集带来介绍性的x86_64扩展,这将可以为操作系统产生准确的核心数。    Two people narrowly survived as their plane veered out of control and burst into flames following a barely-controlled descent onto a Southern California freeway on Tuesday, video shows.,I-91 Crash Landing: Dramatic video obtained by KTLA shows the single-engine Piper Cherokee dropping from the sky, hitting the freeway, and then leaving a trail of burning fuel as it slides toward the sound barrier. Full Video Here: https://t.co/XBQF4QxzsX pic.twitter.com/G90KX5dnN0— KTLA (@KTLA) August 10, 2022,No injuries were reported when the single-engine Piper Cherokee PA-32 tumbled from the sky around midday and bounced across the pavement on Freeway 91 in Corona before hitting a retaining wall and catching fire. Local media notes that a vehicle was struck by the plane in the mayhem, but that the only damage consisted of a broken taillight.,Reportedly, fire crews which raced to the scene were onsite within five minutes and managed to put out the blaze within the hour. Footage posted by the Corona Fire Department shows thick plumes of smoke coming from the wreckage until the team is able to extinguish it with firefighting foam.,On-scene footage from Corona Engine 3 as they arrived on scene to the plane crash on the 91 Eastbound in Corona. #PlaneCrash #91freeway #Corona #CoronaFire pic.twitter.com/a0DwwV4aOB— Corona Fire Dept #CoronaFire (@CoronaFireDept) August 9, 2022,Per the Federal Aviation Administration, the plane was “flying to Corona Municipal Airport” when “the pilot reported an engine issue.” Apparently unable to maintain the necessary altitude, they say the occupants elected instead to attempt an emergency landing on the freeway. Much to the relief of his fellow California motorists, the pilot managed to pull it off.。英特尔研究员和工程师Haochen在为Raptor Lake单独发布GCC编译器补丁后,率先发布了Meteor Lake补丁。然而,这两个补丁的修复并不算大,因为这些变化对两种架构的整体性能来说并不是高度不可或缺的。

B | 英特尔的至强服务器系列CPU严格依赖E-cores,Sierra Forest也被纳入最新的更新中,其中大部分工作对改进更为关键。首先,"sierraforest"编译器目标被启用,以便为下一代服务器处理器提供进一步的指令,例如:AVX-IFMAAVX-VNNI-INT8AVX-NE-CONVERTCMPccXADDPhoronix网站的Michael Larabel从GNU项目网站上恢复了这个列表,同时还有来自英特尔的这个编程参考,以提供关于新指令的信息。

C | x86_64 ISA编程参考手册的截屏前三条指令主要是针对AVX-512视频编解码器,第一条涵盖了整数融合乘加指令,而矢量神经网络指令则利用了INT8推理。AVX-NE-CONVERT通过从m16转换将BF 16 FP元素安装到FP32。最后,CMPccXADD代表"Compare and ADD if Condition is Met",这是AVX-512在这个GCC补丁系列中的最后一套指令。Larabel指出,新的更新仍然可以集成到GCC 13编译器中,该编译器计划在2023年发布,在今年晚些时候的Ubuntu 23.10之后。对英特尔来说,这个时机将是完美的,因为该公司将在2023年第四季度发布用于数据中心的Sierra Forest处理器。了解更多:https://gcc.gnu.org/pipermail/gcc-patches/2022-October/603542.html
