Add the following script:

from multiprocessing import Process
import os


def big_string(size):

    s = 'a' * 1024
    while len(s) < size:
        s = s * 2
    print('completed creating string of length: {}'.format(len(s)))


size = 1 * 1024 * 1024 * 1024
p = Process(target=big_string, args=(size, ))
p.start()
p.join()
if p.exitcode != 0:
    return_error("Return code from sub process indicates failure: {}".format(p.exitcode))
else:
    print("Success allocating memory of size: {}".format(size))

In the SCRIPT SETTINGS section, select the script to run on the Single engine and select the engine where you want to run the script.

Save the Script.

To test the memory limit, type !TestMemory.
