Windows 7中的無規(guī)律內存通道技術

Win7之家（ m.airtaxifl.com）：Windows 7中的無規(guī)律內存通道技術

 Windows 7不僅可以更好地利用運算更快的CPU，同時對單芯片多核心的支持也非常好。64位的Windows 7在單臺機器上甚至可以支持超過64個邏輯處理器。

隨著處理器芯片和操作系統(tǒng)的升級，微軟也對程序員們提出了更高的要求，強調他們開發(fā)出的產品必須適應這樣的升級。基本來說，開發(fā)者們可以利用多核處理器帶來的雙線運行技術提高性能。這就是Windows 7中的無規(guī)律內存通道技術。

Phil Pennington，Windows Server開發(fā)主管透露：“64位版的Windows 7和Windows Server 2008 R2支持單臺機器上超過64個的邏輯處理器。多核處理器的優(yōu)越性現(xiàn)在可以通過Windows 7中的無規(guī)律內存通道技術體現(xiàn)出來。在不遠的將來，4CPU8核心的系統(tǒng)將會實現(xiàn)64顆邏輯處理器的支持。很多服務器級別的解決方案都需要Windows 7中的無規(guī)律內存通道技術來實現(xiàn)對64顆邏輯處理器的支持。”

Windows 7中的無規(guī)律內存通道技術主要用來解決處理器的總線限制。通過Windows 7中的無規(guī)律內存通道技術，機器可以加快硬件設備的運行速度。

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.”
