python编程测试电脑开启最大线程数实例代码

本文实例代码主要实现python编程测试电脑开启最大线程数，具体实现代码如下。

#!/usr/bin/env python  
#coding=gbk  
  
import threading  
import time, random, sys  
  
class Counter:  
  def __init__(self):  
    self.lock = threading.Lock()  
    self.value = 0  
  
  def increment(self):  
    self.lock.acquire()   
    self.value = value = self.value + 1  
    self.lock.release()  
    return value  
  
counter = Counter()  
cond = threading.Condition()  
  
class Worker(threading.Thread):  
  
  def run(self):  
    print self.getName(), "-- created."  
    cond.acquire()  
    #for i in range(10):  
      # pretend we're doing something that takes 10?00 ms  
      #value = counter.increment()   
      # time.sleep(random.randint(10, 100) / 1000.0)  
    cond.wait()  
    #print self.getName(), "-- task", "finished"   
    cond.release()  
      
  
  
if __name__ == '__main__':  
    
    try:  
      for i in range(3500):  
        Worker().start() # start a worker  
    except BaseException, e:  
      print "异常: ", type(e), e  
      time.sleep(5)  
      print "maxium i=", i  
    finally:  
      cond.acquire()  
      cond.notifyAll()  
      cond.release()  
      time.sleep(3)  
      print threading.currentThread().getName(), " quit"
