Answer:
The code for the function is given below in Python language
Explanation:
def append_string_to_file(filename, text):// function takes the filename // and text to append
f = open(filename, 'a')
f.write(text) //function part that writes the text
f.close() //closing the file using the explicit close function
With four processing cores, we get a speedup of 1.82 times.
<h3>
What is Amdahl's Law?</h3>
Amdahl's law exists as a formula that provides the theoretical speedup in latency of the implementation of a task at a fixed workload that can be expected of a system whose resources exist improved.
Amdahl's law exists that, in a program with parallel processing, a relatively few instructions that hold to be completed in sequence will have a limiting factor on program speedup such that adding more processors may not complete the program run faster.
Amdahl's law stands also known as Amdahl's argument. It is utilized to find the maximum expected progress to an overall system when only part of the system exists improved. It is often utilized in parallel computing to indicate the theoretical maximum speed up utilizing multiple processors.
Hence, With four processing cores, we get a speedup of 1.82 times.
