Question
Ophelia is working on a program that uses machine learning to analyze hospital CT scans for signs of cancer.With her first version of the program, the computer took an average of 24 minutes to analyze 1000 images. To improve the performance, she parallelized the image analysis operation. When running the parallelized program on a hospital computer, the computer took an average of 6 minutes to analyze 1000 images.What is the speedup of the parallel solution?Choose 1 answer:Choose 1 answer:(Choice A) 1/4A1/4(Choice B) 18B18(Choice C) 6C6(Choice D) 4D4
Solution
The speedup of a parallel solution is calculated by dividing the time taken by the original program by the time taken by the parallelized program. In this case, the original program took 24 minutes and the parallelized program took 6 minutes.
So, the speedup is 24 / 6 = 4.
Therefore, the correct answer is (Choice D) 4.
