Problem
Research current literature to identify a recent project that has combined the processing capacity of numerous small computers to address a problem. Identify the operating system used to coordinate the processors for this project and discuss the obstacles overcome to make the system work. If your answer includes terms not used in this chapter, be sure to define them. Cite your sources.
Consider a version of the bounded buffer problem in which there is two producer processes (P1and P2) and one consumer processes (P3) all sharing the same buffer. Assume that the size of the buffer is n=4, and that we start with a completely empty buf..
Design and implement a program that simulates a simple CPU scheduling of an operating system. Your simulator must conform to the criteria established in these specifications.
Assume that a computer using direct mapped cache has 2^24 words of main memory and a cache of sixty-four blocks, where each cache block contains sixteen words.
1). An aging algorithm with a = 1/2 is used to predict run times. The previous four runs, from oldest to most recent, are 30, 10, 20, 40 msec. what is the predication about of the next run time? You may use regular arithmetic or binary with bit shift..
What are the implications of this mini-hypervisor? What kind of administration/management would need to be in place to keep all these optimized? What kind of security? Do you really need virtual machines to achieve cloud computing?
write a short memo describing three properties of each of these file systems:FAT16, FAT32, NTFS, and EXT2. Relate the properties to the objectives of all file systems discussed in the chapter.
How are the two types of operating systems similar? Between the two types of Operating Systems, which of the two do you feel is more secure? Please provide a justification and support for your choice.
How could you move all the files that end with an extension *.h in your home directory to the current directory without knowing the full path to the current directory [Hint: use a shortcut for the home directory and current directory.
Assume that word 0 is part of a hole and that the highest word in memory contains valid tries are needed in the page table if traditional(one-level) paging is used? how many page table entries are needed for two-level paging, with 10 bits in ea..
intermediate level tasks below is a simple program. it creates 2 threads. the first thread keeps printing out x on the
What components of program state are shared across threads in a multi-threaded process? Can someone provide the answer with reference to operating system?
What is the turnaround time of each process for each of the scheduling algorithms in part and what is the waiting time of each process for each of these schedul-ing algorithms?
