c# - Windows 中的等效任务集

Question

在 Linux 中，有 taskset实用程序，它允许您为某个进程设置 CPU 亲和性。

在 Windows 环境中是否有等效项？
我想为我的产品设置最大 CPU 阈值，Windows 中是否有任何现有机制提供此功能？

如果有帮助的话，我的产品是用 .Net 开发的

谢谢

Answer 1

是的，有:

Starts a separate window to run a specified program or command.

START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
  [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
  [/NODE <NUMA node>] [/AFFINITY <hex affinity mask>] [/WAIT] [/B]
  [command/program] [parameters]

和选项 /AFFINITY <hex affinity mask>特别是。

AFFINITY    Specifies the processor affinity mask as a hexadecimal number.
            The process is restricted to running on these processors.

            The affinity mask is interpreted differently when /AFFINITY and
            /NODE are combined.  Specify the affinity mask as if the NUMA
            node's processor mask is right shifted to begin at bit zero.
            The process is restricted to running on those processors in
            common between the specified affinity mask and the NUMA node.
            If no processors are in common, the process is restricted to
            running on the specified NUMA node.

如果您只想绑定(bind)到 CPU 0，请指定 0x1 的关联掩码.要绑定(bind)到 CPU 1，掩码应为 0x2 .要绑定(bind)到 CPU 0 和 CPU 1，掩码应为 0x3 , 等等。

您还可以通过将相同的十六进制掩码值分配给 ProcessorAffinity 来在代码中设置 CPU 亲和性。当前进程实例的属性可通过调用 System.Diagnostics.Process.GetCurrentProcess() 获得:

using System.Diagnostics;

Process.GetCurrentProcess().ProcessorAffinity = (IntPtr)0x3;
