Subject: 怎样用程序使服务器最耗电的问题
      各位大大,我现在遇到个奇怪的需求:用程序使服务器最耗电。
我能想到的方法如下:
增加CPU使用率
使用硬盘满负荷

TKS!

建议从硬件上多考虑,比如设计个USB电炉什么的。
软件上,都是如何降低符合,CPU100%,硬盘不停写的程序
1-没用,没意义
2-病毒

你说呢?这需求是够怪,病毒公司吧? :)

Best regards,

硬件测试,计算最大功耗也是可能的。我知道跑CPU的有:cpuburnin
其他的也不知道了:P

cpu 100%太简单了,一行python搞定
9999999999999999999999999999999**999999999999999999999999999999999999999
如果不行,位数再加几位,保证计算机可以一直100%的算下去。

病毒公司这么做也太招摇了吧!

实际情况是,现在的服务器只安装了LINUX,没有跑业务,服务器
使用AC -48V,放在营运商机房,要满负荷运行是为了抢占更多的
电流,为跑业务和扩容留余地。机房电源很紧张。

该方法导致我的电脑死机了四次,是真的,不是笑话

回家换个操作系统和主机试下

如果cpu没有支持空闲状态, 就算 100% 和0%,CPU的耗电都是一样的.
因为 100%和%0 都是根据空闲任务算出来的.

一个usb最大电流500ma,算下来也就几W.
可不可以加显卡之类的用电大户?

现在的CPU都是变频的,当空闲的时候会自动降低CPU主频,
这时候功耗会低一些。

满足楼主要求的程序应该有很多现成的吧,我记得有一个就是算 pi 的,名字忘记了。
那个高精运算,可能是内存不够用了~
至于那个疯狂画图,也有程序用的。
我的想法是要使它最耗电,就要尽量只用 CPU 内部运算,避免读写内存,因为读写内存都有延时的。
