双处理器

本文介绍了双处理器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

问候，全部。 我有一个程序我正试图通过将它放在一台新机器来加速。 新机器是康柏W6000带有双XEON 处理器的2.0 GHz工作站。 我的旧机器速度提高了约7倍，这是300 MHz AMD K6II，但我认为应该有更大的速度增加，因为 两个XEON。 然而，想到了Python（2.4.1）可能我没有能力利用双处理器，所以我的问题： 是吗？ 如果没有，谁知道哪里有可能是人们试图制作的信息 Python在多个处理器上运行64位？ 谢谢！ John Brawley - peace JB jg ******* @ charter http：/ /tetrahedraverse 注意！宪章不阻止病毒， 因此，请不要附件; 他们不会从宪章邮件服务器下载。 __Prearrange__任何附件先和我在一起。

没有人以任何严肃的方式尝试它。

我认为这并不算是使用多个处理器;只有多个程序可以放在不同的盒子上。 多处理意味着共享内存。 此模块可能感兴趣： poshmodule.sf

Greetings, all. I have a program I''m trying to speed up by putting it on a new machine. The new machine is a Compaq W6000 2.0 GHz workstation with dual XEON processors. I''ve gained about 7x speed over my old machine, which was a 300 MHz AMD K6II, but I think there ought to be an even greater speed gain due to the two XEONs. However, the thought occurs that Python (2.4.1) may not have the ability to take advantage of the dual processors, so my question: Does it? If not, who knows where there might be info from people trying to make Python run 64-bit, on multiple processors? Thanks! John Brawley -- peace JB jg*******@charter tetrahedraverse NOTE!

Nobody is trying it in any serious way.

Sure, but you have to write the program to do it. One Python process will only saturate one CPU (at a time) because of the GIL (global interpreter lock). If you can break up your problem into smaller pieces, you can do something like start multiple processes to crunch the data and use shared memory (which I haven''t tinkered with...yet) to pass data around between processes. Or an idea I''ve been tinkering with lately is to use a BSD DB between processes as a queue just like Queue.Queue in the standard library does between threads. Or you could use Pyro between processes. Or CORBA.

I think that doesn''t count as using a the multiple processors; it''s just multiple programs that could be on separate boxes. Multiprocessing means shared memory. This module might be of interest: poshmodule.sf
