What happens if a process tries to access a non-cacheable page? What stages does this procedure entail? Each step should be bulleted.
Step by step
Solved in 2 steps
- What happens if a process tries to access a non-cacheable page? What steps are included in this procedure? Each phase should be separated into bullet points.What happens if a process attempts to visit a page that hasn't been cached? What are the phases in this process? Each step should be broken down into bullet points.Paging: Select all of the following statements that are true. Systems that use paging but do not support inverted page tables maintain at least one separate page table for each process. The frame table is a system-wide data structure. When paging is applied, the selected page size determines which part of a virtual address belongs to the page number and which to the offset. The page size may differ from the frame size. The Translation Look-aside Buffer (TLB) represents a page directory for all pages in the system. Paging is prone to internal fragmentation.
- . Q: In this problem you are to compare reading a file using a single-threaded file server and a multithreaded server. It takes 15 msec to get a request for work, dispatch it, and do the rest of the necessary processing, assuming that the data needed are in a cache in main memory. If a disk operation is needed, as is the case one-third of the time, an additional 75 msec is required, during which time the thread sleeps. How many requests/sec can the server handle if it is single threaded? If it is multithreaded?What happens if a process tries to access a page that was not brought into memory? What are the steps involved in this? Each and every step should be mentioned in bullets form.THREADS in C PROGRAM HELP! Using the thread3.c program provided below, itt will require some code modification. Those modifications include: - instead of 10,000 threads, create 40,000 threads in total - instead of creating just one kind of thread, create 4 kinds of threads (each with 10,000 instances) o group 1: adds 1 to counter o group 2: adds 5 to counter o group 3: subtracts 2 from counter o group 4: subtracts 10 from counter Run the program 5 times and take a screen shot showing the output of the run. Add comments throughout the code please! thread3.c given code: // Compile with://// clang -lpthread thread3.c -o thread3// or// gcc -lpthread thread3.c -o thread3//#include <stdio.h>#include <stdlib.h>#include <pthread.h> #define NTHREADS 10000 // shared variableint counter = 0; // thread to be executed - unspecified variable argumentsvoid *thread (void *vargp) {counter = counter +1;return NULL;} int main() {// array to keep Pthread IDs of created threadspthread_t…
- What happens if a process tries to load a non-cached page? Where can one get a description of the steps involved here? Brief descriptions of each stage are required.Differentiate between caches that are totally associative and those that are directly mapped.What is Translation Look-Aside Buffer used in paging? answer a)It is a memory that is searched when a page is not found in page table b)It is part of the physical memory to hold process control blocks c)It is a bank of special registers inside the processor d)It is an associative memory that can do parallel frame search in hardware
- We know that the paging scheme suffers from internal fragmentation. S1: If the CPU attempts to access the unused portion of the last page, the valid/invalid bits will block such accesses. S2: A possible solution to handle the internal fragmentation issue is to use multiple page sizes. which one is true.Caches have two characteristics, a read architecture and a write policy. Critically discuss the write policy and the read architecture?A cache is set up with a block size of 8 words. There are 128 words in cache and set up to be direct map. You have word address 0x923. Show the word address, block address, tag, and index. Show each access being filled in with a note of hit or miss. You are given word address and the access are: 0xff, 0x08, 0x22, 0x00, 0x39, 0xF3, 0x07, 0xc0.
