- Write a Python script that starts 3 counters using 3 new processes. All processes should be based on a single function (i.e. "counting()"). The function should take 1 parameter representing the target of the counter (i.e. if count_to=12 then the process should print 1,2,3,4...,12 ). Start each process with a different target of the counter. How many objects does the gc track in each process before and after the counter completes its task?PLS explain WHY my answer is wrong and what I can do differently next time so that I can do better next time and provide the correct answer for this question that is incorrect.My task from the teacher is to create a program that solves the three problems using threads in Python: 2 files: reader.py and writer.py In the readers-writers problem there is a common resource where a group of actors called readers want to read from the resource and another group of actors called writers want to write to the resource. The basic synchronization problem that needs to be solved is:1. Mutual exclusion of the resource, where:• only one writer may print at a time, and• no writer may write while a reader is reading.An ordinary mutex lock that is applied equally to all actors can solve this but will lead to only one actor being able to enter its critical section at a time. This is a problem as we normally want several readers to be able to read at the same time. The next problem that needs to be solved is therefore the following: 2. Several readers should be able to read the resource at the same time.In a solution where several readers can read simultaneously and lock out…
- I need to implement in C the First-come, first-served (FCFS), which schedules tasks in the order in which they request the CPU. Priorities range from 1 to 10. Where the file driver.c reads in the schedule of tasks, inserts each task into a linked list, and invokes the process scheduler by calling the schedule() function. The schedule() function executes each task according to the specified scheduling algorithm. Tasks selected for execution on the CPU are determined by the pickNextTask() function and are executed by invoking the run() function defined in the CPU.c file. A Makefile is used to determine the specific scheduling algorithm that will be invoked by driver.Consider a computer environment in which there are 4 magnetic drives, 2 printers, 3 scanners, and 1 optical drive. Three processes P1, P2, P3 are using these resources. At any point in time, the allocations and requests for these resources are as follows. Allocations: Magnetic drive Printer Scanner Optical drive P1 1 P2 2 1 P3 1 Requests: Magnetic drive 2 Printer Scanner Optical drive P1 1 P2 1 1 P3 2 1 Is there any way that the processes can complete without deadlock? If yes, explain how. If not, explain why not.2. a) Your colleague has invented a new scheduling algorithm using the multilevel queue approach. This list of processes showing CPU burst times is below. There are three queues used in the application. The processes all start on the first queue and receive upto 10ms of burst time. Once the process has received the 10ms on the first queue, if the process still requires burst time it is passed to the second queue where it receives upto 20ms. Once the process has received the 20ms on the second queue, if the process still requires burst time it is passed to the third queue where it receives CPU time until it is completed. The operating system will only start allocating CPU time to processes on the second queue when queue 1 is empty. The operating system will only start allocating CPU time to processes on the third queue when queue 2 is empty. Process Number P1 P2 P3 P4 Burst time (ms) 21 8 35 50 i) Does this algorithm give higher priority to any queue over the others and any processes…
- Write a C program to create two processes P1 and P2. P1 takes 2 integers (x,y) and passes it to P2. P2 performs mathematical operations over receivedintegers and sends it back the output array to P1 for printing.Write a C program that takes a list of command line arguments, each of which is the full path of a command (such as /bin/ls, /bin/ps, /bin/date, /bin/who, /bin/uname etc). Assume the number of such commands is N, your program would then create N direct child processes (ie, the parent of these child processes is the same original process), each of which executing one of the N commands. You should make sure that these N commands are executed concurrently, not sequentially one after the other. The parent process should be waiting for each child process to terminate. When a child process terminates, the parent process should print one line on the standard output stating that the relevant command has completed successfully or not successfully (such as "Command /bin/who has completed successfully", or "Command /bin/who has not completed successfully"). Once all of its child processes have terminated, the parent process should print "All done, bye-bye!" before it itself terminates. Note: do…Write a Python program using the multiprocessing method and the Pool object that spawns 10 processes with inputs 1,...,10 and each process calculates the sum of integers up to and including its input and returns this sum.
