Windows 7中的无规律内存通道技术

Win7之家（ www.win7china.com）：Windows 7中的无规律内存通道技术

 Windows 7不仅可以更好地利用运算更快的CPU，同时对单芯片多核心的支持也非常好。64位的Windows 7在单台机器上甚至可以支持超过64个逻辑处理器。

随着处理器芯片和操作系统的升级，微软也对程序员们提出了更高的要求，强调他们开发出的产品必须适应这样的升级。基本来说，开发者们可以利用多核处理器带来的双线运行技术提高性能。这就是Windows 7中的无规律内存通道技术。

Phil Pennington，Windows Server开发主管透露：“64位版的Windows 7和Windows Server 2008 R2支持单台机器上超过64个的逻辑处理器。多核处理器的优越性现在可以通过Windows 7中的无规律内存通道技术体现出来。在不远的将来，4CPU8核心的系统将会实现64颗逻辑处理器的支持。很多服务器级别的解决方案都需要Windows 7中的无规律内存通道技术来实现对64颗逻辑处理器的支持。”

Windows 7中的无规律内存通道技术主要用来解决处理器的总线限制。通过Windows 7中的无规律内存通道技术，机器可以加快硬件设备的运行速度。

Windows 7 will be able to take advantage not only of faster CPUs, but of multiple processors on a single chip. The 64-bit edition of the operating system in particular will be able to support over 64 Logical Processors per machine.

In this regard, Microsoft underlined the need for software developers to adapt their applications in accordance with the evolution of processor chips and that of the Windows operating system. Essentially, consistent gains in performance are synonymous with using parallel programming techniques in concordance with many-core processors. This is where non-uniform memory access (NUMA) comes in.

“The 64-bit versions of Windows 7 and Windows Server 2008 R2 support more than 64 Logical Processors (LP) on a single computer,” Phil Pennington, Windows Server Technical Evangelism, revealed. “New processors are now appearing that leverage non-uniform memory access (NUMA) architectures. Within the near future, a system with 4 CPU sockets, 8 processor-cores per socket, and with Simultaneious Multi-Threading (SMT) enabled per core, will achieve 64 Logical Processors. Many server-class solutions will need to be architected with NUMA awareness in order to achieve linear performance scaling on 64+ LP systems.”
