9大巨头公司造了一个新总线

2019-03-15 by:CAE仿真在线来源:互联网

为了提供数据中心的数据传输性能,Alibaba, Cisco, Dell, Facebook, Google, HP, Huawei,Intel和Microsoft 一起发布了新一代互连总线 CXL(Compute Express Link)。

不知这是不是巧合,正好昨天NVIDIA发布并购Mellanox,Intel就发布了CXL总线。

CXL是一个基于PCIe Gen5的标准,旨在解决下一代产品中的缓存一致性和互连问题。UPI应用于Intel的CPU之间,解决不了CPU与其它芯片的连接问题(有的人肯定会想,PCIE不就可以么)。随着公司和业界扩展到采用GPU、FPGA和其它加速器,对更广泛和更快的互连的需求已经成为一个更大的行业主题。

下面是从CXL官网上看到的内容,对CXL做了一个简短的介绍:

Key Industry Players Converge to Advance CXL, a New High-Speed CPU Interconnect for Breakthrough Data Center Performance Key Highlights:

• Alibaba, Cisco, Dell EMC, Facebook, Google, Hewlett Packard Enterprise, Huawei, Intel Corporation and Microsoft team up on the new Compute Express Link (CXL) technology to accelerate rapidly growing data workloads such as Artificial Intelligence and Machine Learning, rich media services, High-Performance Computing and Cloud applications.

• CXL Specification 1.0 ratified to address growing high-performance CPU-to-Device, interconnect needs and provide improved memory coherency for higher performance of data-intensive applications.

• The new open standard will help foster an open accelerator ecosystem for high performance, heterogeneous computing. Interested member companies and institutions are encouraged to join.
