把循环改成并行可以显著提升代码运行效率

R语言

借助furrr和future包

WORKER_NUM = 10
future::plan(future::multisession, workers = WORKER_NUM)        
furrr::future_walk(elementlist, function(ele){...})

Python

借助concurrent.futures包
把需要遍历的元素放在 element_list 里面

import sys, concurrent.futures

WORKER_NUM = 10
def function_for_each_element(ele):
    # Defines your function here

with concurrent.futures.ProcessPoolExecutor(max_workers=WORKER_NUM) as executor:
    executor.map(function_for_each_element, element_list)
