Here is one way you can do this using the '''numba''' and hashlib libraries in python:

'''
from numba import jit, cuda
import hashlib

@jit(target_backend='cuda')
def parallel_sha256(arr: list[str]):
    m = hashlib.sha256()
    for element in arr:
        for _ in range(100_000):
            m.update(bytes(element))
    m.digest()
'''

This code calls the '''update''' method on each element of the list 100,000 times and then calls '''digest''' to execute the '''sha256''' algorithm. Using the '''jit''' decorator, the code will attempt to be executed on the GPU.
