我怎么能强调我的手机的CPU编程？ [英] How can i stress my phone's CPU programatically?

问题描述

所以我超频我的电话1.664ghz，我知道有一些测试你的手机的CPU性能和的 stressers 的，但我想使我自己好歹。什么是真正让你的CPU工作的最佳方法？我的想法只是让一个循环做做一些费时数学100万次迭代...但没有工作监守我的手机在几毫秒内，我认为这样做是...我想...迭代的万亿应用程序冻结了，但我的任务管理器没有显示，即使正在使用的应用程序的CPU。通常压力测试的应用程序显示为红色，并说CPU：85％的RAM：10MB ......那么，怎样才能我真的让我处理器认真思考

So i overclocked my phone to 1.664ghz and I know there are apps that test your phone's CPU performance and stressers but I would like to make my own someway. What is the best way to really make your CPU work? I was thinking just making a for loop do 1 million iterations of doing some time-consuming math...but that did not work becuase my phone did it in a few milliseconds i think...i tried trillions of iterations...the app froze but my task manager did not show the cpu even being used by the app. Usually stress test apps show up as red and say cpu:85% ram: 10mb ...So how can i really make my processor seriously think?

推荐答案

要编译正则表达式的字符串：

To compile a regex string:

Pattern p1 = Pattern.compile("a*b"); // a simple regex
// slightly more complex regex: an attempt at validating email addresses
Pattern p2 = Pattern.compile("[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+(?:[A-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)\b");

您需要在后台线程启动这些：

You need to launch these in background threads:

class RegexThread extends Thread {
   RegexThread() {
      // Create a new, second thread
      super("Regex Thread");
      start(); // Start the thread
   } 

   // This is the entry point for the second thread.
   public void run() {
      while(true) {
        Pattern p = Pattern.compile("[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+(?:[A-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)\b");
      }
   }
}

class CPUStresser {
   public static void main(String args[]) {
      static int NUM_THREADS = 10, RUNNING_TIME = 120; // run 10 threads for 120s
      for(int i = 0; i < NUM_THREADS; ++i) {
         new RegexThread(); // create a new thread
      }
      Thread.sleep(1000 * RUNNING_TIME);
   }
}

（以上从这里拨款code ）
