我试图在python下运行并行进程(在ubuntu上).

我开始使用多处理,它适用于简单的例子.
然后是泡菜错误,所以我切换到了悲.. 我对不同的选项感到困惑,所以写了一个非常简单的基准测试代码.

import multiprocessing as mp
from pathos.multiprocessing import Pool as Pool1
from pathos.pools import ParallelPool as Pool2
from pathos.parallel import ParallelPool as Pool3
import time

def square(x):  
    # calculate the square of the value of x
    return x*x

if __name__ == '__main__':

    dataset = range(0,10000)

    start_time = time.time()
    for d in dataset:
        square(d)
    print('test with no cores: %s seconds' %(time.time() - start_time))

    nCores = 3
    print('number of cores used: %s' %(nCores))  


    start_time = time.time()

    p = mp.Pool(nCores) …
