Assume we have a cluster consisting of 4 identical computer nodes. Now, let’s say the program has been parallelized or partitioned for parallel execution on such a cluster. 25% of the program code must be executed sequentially, while the remaining 75% can be run parallel on the available nodes. Using Amdahl’s law, calculate the speed up if the cluster is upgraded to have 16 nodes compared to 4 nodes.
4. The following is the memory configuration at a given point in time where dynamic partitioning scheme is used. The shaded areas indicate memory spaces already allocated to other processes, while the white spaces are holes (free memory spaces). The next FOUR (4) memory requests are 30M, followed by 50M, 20M and 40M (in order). Shade and indicate clearly which memory block will be allocated to each request using the first- fit and next-fit placement algorithms. (First-fit) 20M (Best-fit) 20M (Next-fit) 20M 1 80M 2 3 4 80M b. Given a process segment table as follows: Segment 0 80M (X is the lastest allocated block) 20M Base 496 1202 232 2359 1877 20M 20M Length 691 85 198 109 258 50M 50M 50M 10M 10M 10M X 30M 30M 30M Explain the basic use of segment table in process segmentation and its difference with paging. Give one example on how the information in the given process segment table is used.
