Data Warehousing CS614 Assignment No 3 Spring 2020
Objectives:After completing this assignment, the students will be able to:· compare Parallel Processing and Serial Processing· describe what and when to Parallelize· calculate Speed up using Amdahl’s Law InstructionsPlease read the following instructions carefully before submitting assignment:It should be clear that your assignment will not get any credit if: · Assignment is submitted after due date.· Submitted assignment does not open or file is corrupt.· Assignment is copied (From internet/ to from students).· Assignment is submitted other than word format (.doc, .docx). Assignment: Scenario: XYZ is a fabric manufacturing company. This company is planning to implement DWH for its existing OLTP system implemented in 300 + stores all over Pakistan. Size of company’s Database is approx. 298 GB that grows at the rate of 0.8 GB per day approximately. Company has designed a state of the art DWH in its head office in terms of hardware and software. Hardware consists of 7 Systems having quad-core processors. In ideal situation, a complex query would return results in 27 minutes on single processor (serial execution). After analyzing the scenario given above, you are required to answer the following questions; Question # 1 – If a complex query is executed parallel on 6 single core processors then what would be the quantified speed up time. Question # 2 – Calculate Speed up ratio using Amdahl’s Law, if 80% of query processing is done through parallel execution on DWH hardware. Deadline:Your assignment must be uploaded on VULMS on or before July 27, 2020. While July 28, 2020 will be a bonus day for assignment submission.
