是否可以限制 Parallel.ForEach 的内核? [英] Is it possible to limit the cores for Parallel.ForEach?

问题描述

我在我的代码中使用了 Parallel.ForEach.我所有的 8 个内核都达到 100%.这对服务器上运行的其他应用程序不利.是否可以将执行限制为 4 个内核?

I'm using a Parallel.ForEach in my code. All my 8 cores go to 100%. This is bad for the other apps that are running on the server. Is it possible to limit execution to like 4 cores?

推荐答案

将 ParallelOptions 的实例传递给 ParallelOptions.MaxDegreeOfParallelism 设置为 4 到 Parallel.ForEach.

Pass an instance of ParallelOptions with ParallelOptions.MaxDegreeOfParallelism set to 4 to Parallel.ForEach.

尽管如此，这在其他机器上可能没有意义，因为它们的内核可能比您多或少.一般来说，你应该让框架决定并行度.

Nevertheless this might not make sense on other machines, that might have more or less cores than you. In general you should let the framework decide the degree of parallelism.
