9大巨頭公司造了一個(gè)新總線

2019-03-15 by:CAE仿真在線來(lái)源:互聯(lián)網(wǎng)

為了提供數(shù)據(jù)中心的數(shù)據(jù)傳輸性能,Alibaba, Cisco, Dell, Facebook, Google, HP, Huawei,Intel和Microsoft 一起發(fā)布了新一代互連總線 CXL(Compute Express Link)。

不知這是不是巧合,正好昨天NVIDIA發(fā)布并購(gòu)Mellanox,Intel就發(fā)布了CXL總線。

CXL是一個(gè)基于PCIe Gen5的標(biāo)準(zhǔn),旨在解決下一代產(chǎn)品中的緩存一致性和互連問(wèn)題。UPI應(yīng)用于Intel的CPU之間,解決不了CPU與其它芯片的連接問(wèn)題(有的人肯定會(huì)想,PCIE不就可以么)。隨著公司和業(yè)界擴(kuò)展到采用GPU、FPGA和其它加速器,對(duì)更廣泛和更快的互連的需求已經(jīng)成為一個(gè)更大的行業(yè)主題。

下面是從CXL官網(wǎng)上看到的內(nèi)容,對(duì)CXL做了一個(gè)簡(jiǎn)短的介紹:

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.
