步骤4: 使用 concurrent.futures 实现并行处理 我们将利用ThreadPoolExecutor或者ProcessPoolExecutor来实现并行处理。这里使用ThreadPoolExecutor作为示例。 defmain():numbers=[1,2,3,4,5]# 创建一个列表,包含我们要计算的数字results=[]# 存储结果的列表# 使用ThreadPoolExecutor管理线程池withconcurrent.futures.Thread...
# 使用线程池withconcurrent.futures.ThreadPoolExecutor()asexecutor:# 这里可以创建进程池: executor = concurrent.futures.ProcessPoolExecutor() 1. 2. 3. 4. 提交任务 使用executor.submit()来提交要并行执行的任务,并将任务输入列表传递给它。 tasks=[executor.submit(task,n)forninrange(5)]# 提交5个任务 ...
time.sleep(1)if__name__ =='__main__':foriinrange(10): p = MyProcess(i) p.start() 三、 jobLib.Parallel函数 Joblib:将Python代码转换为并行计算模式,可以大大简化我们写并行计算代码的步骤.过操作该包内的函数来实现目标代码的并行计算,从而提高代码运行效率。
进程是通常彼此独立运行的程序的实例。例如,如果启动Java程序,则操作系统会产生一个新程序,该程序process(进程)可与其他程序并行运行。在这些进程中,我们可以利用线程并发执行代码,因此我们可以充分利用CPU的可用内核。 与线程不同,进程不会彼此共享资源。process(进程)是资源的单位,而thread(线程)是调度和执行的单位。
We show, via experiments on the Blue Waters supercomputer, that Parsl executors can allow Python scripts to execute components with as little as 5 ms of overhead, scale to more than 250000 workers across more than 8000 nodes, and process upward of 1200 tasks per second. Other Parsl ...
