As your overall task, BankWorld wants you to design a parallel computing approach to analyzing this data. You are to produce a mailing list of all customers who charged a cumulative total of at least $500 at any combination of home product centers within the past year. BankWorld’s marketing department believes that it can sell copies of the mailing list (of all good home product center customers) back to each of these stores, which will in turn use the lists to send advertising circulars to the customers. Without stopping to analyze the privacy issues involved, you immediately jump into the task of summing purchases, by customer, from a list of businesses identified as being home product centers.
