Section B

 

Case Study

 

ABC.com is a website where you can watch original movie DVDs.  It currently maitains the list of visitors and details of their visit.  The website gets almost 1 billion visitors everyday and at midnight it processes all the information.  It takes almost 5 hours to pocess all the information and the system remains down for that long. It causes the company a huge loss.  The company decided to buy a super computer for faster analysis. The supercomputer has 10 processors. Now the need is to design a parallel algorithm for the following problems:


 

We now have the list of visitors for the day and the number of movies they watched.



 

Q1. Design a parallel algorithm that would sort the names alphabetically. 


 

 

Q2. Now write a parallel search algorithm that would find a visitor "John" in this sorted list and show how many movies he watched. 

 


 

Q3. Can either sorting or searching achieve super linear speedup?
