在双核或四核CPU上运行软件 [英] Running software on Dual or Quad core CPU

问题描述

只是想知道，如果有一个双核或四核CPU，一个运行多个不同的程序，或同一个程序的多个副本，那么

操作系统（XP或2003）在单独的核心上运行每个单独的程序？

或者在命令

行或通过代码强制它们启动程序时需要做什么$>
谢谢

命令行上启动程序时执行某些操作，或者通过代码强制它们在单独的内核上运行？

他们既可以使用核心，也可以在运行时切换。你不需要b $ b需要做任何事情。

多核的性能优势实际上取决于是否对应用程序进行了任何多线程处理

。

当你说对应用程序完成多线程时，你只是意味着

你在程序中启动几个不同的线程来完成

各种各样的东西。


例如，我刚写了一个应用程序在互联网上出去，

从服务器收集三条信息。我让它在三个单独的线程中执行此操作。这种类型的东西会比一个核心更有价值吗？

Just wondering, if one has Dual or Quad core CPU and one is running multiple
different programs, or multiple copies of the same program, does the
operating system (XP or 2003) run each individual program on seperate cores?
or does one need to do something when starting the programs on the command
line or through code to force them to run on seperate cores?

Thanks
harry

They could both use either cores and switch between while running. You don''t
need to do anything.

Also the performance benefit of multiple cores really depends if there was
any multi-threading done to the application.

When you say multi-threading done to the application, do you simply mean
that within the program you start several different threads to accomplish
various things.

For example, I just wrote an application to go out on the Internet and
gather three pieces of information from a server. I had it do this in three
separate threads. Is this the type of thing that would benefit from more
than one core?
