CPU亲和度(CPU affinity)是指将一个进程或线程限制在特定的CPU核心上运行的技术。在多核处理器系统中,操作系统会自动将进程或线程分配到可用的CPU核心上,但有时候我们希望显式地控制进程或线程在哪个CPU核心上执行。 作用和原理 性能优化:将特定的进程或线程绑定到一个或多个CPU核心上,可以避免因为核心切换而导致...
[System.Runtime.Versioning.SupportedOSPlatform("windows")]publicIntPtr ProcessorAffinity {set; } 屬性值 IntPtr 指向一組位元的IntPtr,其中每個位元表示執行緒可以在其上執行的處理器。 屬性 SupportedOSPlatformAttribute 例外狀況 Win32Exception 處理序相似性不能被設定。
Enable processor affinity. Set theSMPAffinitizedmetabase property totrue, which indicates that a particular worker process assigned to an application pool can also be assigned to a specified CPU. Assign processor affinity. Set theSMPProcessorAffinityMaskmetabase property, which configures a hexadecimal pr...
软亲和性: 就是进程要在指定的 CPU 上尽量长时间地运行而不被迁移到其他处理器,Linux 内核进程调度器天生就具有被称为 软 CPU 亲和性(affinity)的特性,这意味着进程通常不会在处理器之间频繁迁移。这种状态正是我们希望的,因为进程迁移的频率小就意味着产生的负载小。 硬亲和性:简单来说就是利用 Linux 内核提供...
32-bit Windows supports a maximum of 32 processors. Therefore, functions such as GetProcessAffinityMask simulate a computer with 32 processors when called under WOW64.The affinity mask is obtained by performing a bitwise OR operation of the top 32 bits of the mask with the low 32 bits. ...

Processor Affinity is useful if you have a heavy program like video rendering. When you dedicated a core for the video editing program, it ensures that the core of the processor is always dedicated to the task. It improves performance because it reduces reduce cache problems as there is no ...
If an instance of Application Object Server (AOS) has multiple processors, you can specify which processors host the AOS service. When you specify one or more processors for a service, you are said to set processor affinity. By setting processor affinity, you can help improve server performance...
In addition to the taskset command, processor affinity can also be set using the sched_setaffinity() system call. The following code excerpt retrieves the CPU affinity information for a specified PID. If the PID passed to it is 0, it ...
