What is the use of multiprogramming on individual processors?
In the usual multiprocessor, which is dealing with independent or coarse-grained synchronization granularity, it is clear that every individual processor must be able to switch among a number of processes to achieve high use and therefore better performance. But when we deal with medium grained applications running on a multiprocessor with several processors then the situation is less clear. When several processors are available, it is no longer dominant that each single processor be busy as much as possible. Relatively, we are apprehensive to provide the best performance on average for the applications. The application that consists of a number of threads may possibly run poorly unless all its threads are available to run concurrently.
When do we write a page from physical memory back to the disk? In general, caches have two broad types of writing policies. One approach is a write-through cache. In this case,
It uses unix commands such as forks and pipe .I need solution to this project
what is deckers algorithm
draw a state diagram showing the transissions of a process from creation to termination
Determining the time quantum for a job is a critical task. Given the assumptions that the average switching time between processes is s, and the average amount of time an I/O bo
Now let us present an implementation of a producer-consumer system using condition variables. This implementation works. dequeue() lock(A) while (queue empty) { wait(A, C)
Suppose a logical address space is 1KB, and the page-size is 16 bytes. Assume no page is in the main memory for this process initially and the pure demand paging is used. Current f
For this exercise I wanted to give you some real-world examples of useful bash scripts. Therefore, you will write a couple of scripts that I actually use in my teaching to automate
