Dynamic Multithreading

An algorithm that executes a single instruction in a uniprocessor system is called a serial algorithm. In the case of a multiprocessor computer system, multiple instructions are executed in parallel. A multithreaded algorithm is an algorithm that enables multiple instances of the code to be executed concurrently.Multithreading is a concept that allows the CPU to execute threads independently while sharing similar resources. It is an important CPU feature that works on the process. Thread is a sequence of instructions that executes in parallel with other threads. Because of multithreading, multiple tasks can be performed within a single process.

Q1. Consider a memory of size 16KB. This memory is allocated in increments of 1KB and the memory is initially empty. Use the various contiguous allocation schemes (First-fit, Best-fit, and Worst-fit) for satisfying the memory allocation/deallocation requests for processes requesting the sizes shown in the table below. Process Requested size (in KB) A B C D E F G H 4.2 7.2 2.5 4.5 3 2.7 1.5 2 Allocate(P) represents an allocation request by process P for the size shown in the above table Deallocate(P) is used to indicate deallocating the memory allocated to process P B 8KB We represent this memory by [B,2,H,4]. To represent memory, in square brackets, we use P to indicate a memory segment allocated to P and we use an integer to indicate a contiguous free part of memory. For example, after the following sequence of requests: Allocate(B), Allocate(G), Allocate(H), Deallocate(G) memory will look like this: free H free 2KB 2KB 4KB I 3.6 If X is requesting 6 KB the answer will be: [B,2,H,4]…
For Heap File with a page directory, assume that a page can contain up to 100 directory entries and a page can contain 1000 records, for a file of 1,000,000 records, what is the number of pages to store these records, assuming that on average data pages are filled up 70%? With this data page utilization, what is the number of pages to store the directory, assuming that each directory page is full? Assuming both the directory and the file are stored on disk, what is the I/O cost to insert one record in worst case, and in the average case?
Consider the following set of processes, with the length of the CPU burst given in milliseconds.

Draw the Gantt chart and demonstrate the start and end time of each process that illustrates the execution of these processes using round robin scheduling (time quantum-4 milliseconds). b. Calculate the average waiting time and the average turnaround time of the three processes.
Last solution had mistakes: For these questions, assume that memory partitions can be subdivided; multiple processes may fit in a partition if there is room. For example, if we had a 30-MB partition and a 20-MB process that fits in the partition, the partition’s new size is 10 MB after placing the process in it. If a second, 8-MB process arrives, we may place it in the partition, leaving 2 MB free in the partition. (The original memory partition then contains a 10-MB and an 8-MB process.) Consider a swapping system where memory has partitions of the following sizes: 180 MB, 100 MB, 40 MB, 200 MB, 300 MB, and 150 MB (in order). For first fit, how are processes of sizes 180 MB, 30 MB, 150 MB, 80 MB, 100 MB, and 70 MB placed (in order)? Indicate which requests (if any) cannot be satisfied. Repeat question (a) for best fit. Repeat question (a) for worst fit.

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.
