Option is not set to the default , it may restrict the number of processors available to sql server on symmetric multiprocessing systems 選項(xiàng)不設(shè)置為默認(rèn)值,則可能會(huì)限制可用于對(duì)稱(chēng)多處理( smp )系統(tǒng)上的sql server的處理器數(shù)。
While faster processors and symmetric multiprocessing ( smp ) speed applications , i / o creates a bottleneck between end users and the information 在更快的處理器和對(duì)稱(chēng)多處理( smp )加速應(yīng)用的同時(shí), i / o就成了最終用戶(hù)與信息之間的瓶頸。
In the traditional model for multiprocessor support symmetric multiprocessing , or smp , each processor has equal access to memory and i o 在支持多處理器的傳統(tǒng)模型中(對(duì)稱(chēng)多處理,或者說(shuō)是smp ) ,每個(gè)處理器對(duì)內(nèi)存和i / o有同等的訪(fǎng)問(wèn)權(quán)限。
Option to provide a means of reducing the system overhead associated with the excessive context switching sometimes seen in symmetric multiprocessing environments 選項(xiàng)可以減少有時(shí)在對(duì)稱(chēng)多處理( smp )環(huán)境下遇到的、與過(guò)多的上下文切換有關(guān)的系統(tǒng)開(kāi)銷(xiāo)。
Since a symmetric multiprocessing computer has only one checkpoint thread , the multiple threads when using numa result in an increase of the speed of the checkpoint 由于對(duì)稱(chēng)多處理( smp )計(jì)算機(jī)僅有一個(gè)檢查點(diǎn)線(xiàn)程,因此,在使用numa時(shí),多個(gè)線(xiàn)程將導(dǎo)致檢查點(diǎn)的速度增加。
Note that symmetric multiprocessing the ability to run processes on multiple processors is not supported on this hardware , due to stability problems with such configurations 注意, symmetric multiprocessing smp進(jìn)程運(yùn)行在多處理器上的能力因?yàn)樵撆渲孟路€(wěn)定性的問(wèn)題,在此硬件上不被支持。
The other is by means of splitting or partitioning the workload into multiple logical partitions and running the database against multiple logical nodes on a symmetric multiprocessing machine 另一種方法就是通過(guò)將工作負(fù)載分割或劃分成多個(gè)邏輯分區(qū),然后在對(duì)稱(chēng)多處理機(jī)( smp )機(jī)器的多個(gè)邏輯節(jié)點(diǎn)( mln )上運(yùn)行該數(shù)據(jù)庫(kù)。
百科解釋
Symmetric multiprocessing (SMP) involves a multiprocessor computer hardware architecture where two or more identical processors are connected to a single shared main memory and are controlled by a single OS instance. Most common multiprocessor systems today use an SMP architecture.
