如何为 jupyter notebook 分配更多的 CPU 使用率？

Question

I am using a shared computer with several CPUs, but when I run a notebook it only uses one CPU. Is there any way I can assign the jupyter notebook to use more of the CPUs available?

Answer 1

A way to "assign" more CPU power to a task is not associated with Jupyter IDE but rather is a library within python. I would recommend using the multiprocessing library. Please refer to this link for the official multiprocessing documentation. A sample code is provided below:

import multiprocessing


def main(number):
    print(number)


if __name__ == '__main__':
    p1 = Process(target=main, args=(1,))
    p2 = Process(target=main, args=(2,))
    p1.start()
    p2.start()
    p1.join()
    p2.join()

You can think of each of these processes as more CPU power being used to perform a task.
