c# - Windows中的等效任务集

Question

在 Linux 中，有一个任务集实用程序，它允许您为某个进程设置 CPU 亲和性。

在 Windows 环境中是否有等价物？
我想为我的产品设置最大 CPU 阈值，Windows 中是否存在提供此功能的现有机制？

如果有任何帮助，我的产品是在 .Net 中开发的

谢谢

Answer 1

就在这里：

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]

尤其是选项/AFFINITY <hex affinity mask>。

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.

如果您只想绑定到 CPU 0，请指定0x1. 要绑定到 CPU 1，掩码应该是0x2. 要绑定到 CPU 0 和 CPU 1，掩码应该是0x3，依此类推。

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

using System.Diagnostics;

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