Back to system programming! Alice is now tasked with writing a program to do matrix multiplication. However, Bob has once again replaced Alice’s computer with a uniprocessor toaster behind her back. The program will be graded on speed, so she wishes to make the program run as fast as possible. Instead of trying to come up with a more efficient algorithm, Alice is determined to use either more threads (pthread_create) or more processes (fork) to improve performance. Should Alice use more threads or more processes (assuming that you can only pick one)? Explain why.
