Intel preps interconnect for server CPUs

Rick Merritt

SAN JOSE, Calif. – Intel Corp. is not providing details, but it has disclosed plans that confirm industry speculation of recent weeks: The x86 giant is developing a next-generation interconnect it will integrate in future Xeon and Atom server processors addressing a range of uses from supercomputers to microservers.

The news is timed to compete with an announcement later on Monday (Sept. 10) from Advanced Micro Devices about the Freedom Fabric it acquired with startup SeaMicro. AMD is expected to try to make that interconnect an industry standard for its server CPUs, and probably those of emerging ARM-based server SoCs.

Interconnects--sometimes called fabrics--are key to linking tens to hundreds of thousands of processors in a broad range of servers. They are used in everything from the world’s most powerful supercomputers to large cloud computing data centers and microservers, dense chassis packed with processors generally used as Web servers.

The industry has been anticipating an Intel move into interconbnects after three recent acquisitions. In April, Intel bought an interconnect group from Cray for $140 million. In January, it acquired the Infiniband chip business of QLogic for $125 million, and in July 2011 it bought Fulcrum for an undisclosed sum.

“We are putting a salable fabric into the processor using the assets we have with our recent acquisitions,” said Raj Hazra, general manager of Intel’s technical computing group. “We think this integration happens much sooner than end of decade as some people have suggested, tying it to exascale supercomputers,” he said.

The new Intel interconnect aims to cover the waterfront in applications. At the low end, it could be used in microservers to link a hundred or more processors at tens of GBytes/second with latencies of less than 1,000 nanoseconds. At the high end, it ultimately will scale up to linking hundreds of thousands of processors at hundreds of GBytes/second at latencies measured in tens of nanoseconds.

The interconnect will appear in Xeon, Xeon Phi and Atom processors geared for such servers. It’s not clear when Intel will relesase details of the new interconnect and CPUs using it, although some details may emerge from this week’s Intel Developer Forum.

“We haven’t finished the road map planning,” said Hazra.

Most of the work defining the interconnect appears to be going on inside Intel with the help of a few software companies and systems integrators. “We have strong software ecosystem,” he said.

The technology likely will emerge as a set of new capabilities layered on to the exsiting Quick Path Interconnect Intel uses as its proprietary processor bus. The technology may use elements of existing Ethernet, Infiniband and proprietary interconnects inclouding RapidIO, now being proposed as a competing standard for ARM server SoCs.

“We’ve looked at all the potential solutions and their pros and cons,” Hazra said.

Intel collaborated with SeaMicro on the startup's Atom- and Xeon-based server designs until AMD bought the startup earlier this year. “We know what their fabric was and it was interesting for a microserver class products line, but I have no idea where it has evolved,” he said.

  • 什么是处理器
  • 处理器是解释并执行指令的功能部件。每个处理器都有一个独特的诸如ADD、STORE或LOAD这样的操作集,这个操作集就是该处理器的指令系统。计算机系统设计者习惯将计算机称为机器,所以该指令系统有时也称作机器指令系统,而书写它们的二进制语言叫做机器语言。注意,不要将处理器的指令系统与BASIC或PASCAL这样的高级程序设计语言中的指令相混淆。指令由操作码和操作数组成,操作码指明要完成的操作功能,而操作数则表示操作的对象。

  • 什么是服务器?
  • 服务器是一种高性能计算机,作为网络的节点,存储、处理网络上80%的数据、信息,因此也被称为网络的灵魂。服务器的构成与微机基本相似,有处理器、硬盘、内存、系统总线等,它们是针对具体的网络应用特别制定的,因而服务器与微机在处理能力、稳定性、可靠性、安全性、可扩展性、可管理性等方面存在差异很大。
