C++ 5 state single threaded processor
ONLY MAIN.CPP IS TO BE MODIFIED Description In this assignment you will implement a basic single threaded 3 state processor with the following process states: ready, blocked, and processing. The 2 additional states are notArrived and done (these are analogous to the New and Exit states we discussed in class). Notes: You place a process on the "processor" by marking the processor as unavailable - processorAvailable = false; Then the process that is to be running has its processor time incremented for the time units that it is to be running When a process is placed on the processor it should continue to process until it is done or blocked by an IOEvent When a process is complete or blocked, the first ready process in the vector (by index) should be placed on the processor. This is a basic first come, first served scheduler Processor Flow Set processes to ready (when they arrive and become unblocked) Check for the first process that is ready "Process" (processorAvailable = false) for 1 time unit (i.e., one while loop iteration) Repeat 3 until done or blocked (make sure that time isn't standing still for other processes) Repeat steps 1-4 until all processes are co...

C++ simulator of simple CFS scheduler
In this assignment, you are requested to develop a simple simulator for the CFS scheduler. The simulator must implement the following features: 1. to take as input a number of processes along with their priorities, their burst times, and the time they appear in the system. The input can be given as a text file which may have been generated by a separate program or it can be generated on-the-fly with random data if the user enters only the number of processes without the rest of the information. 2. to use a Red-Black tree structure with support for insertion (creation of new processes), deletion (terminated processes), and to update the tree according to the self-balancing rules. 3. to calculate the waiting and response time of each process in the system as well as the corresponding average values. 4. to generate statistics of how many times each process was preempted and how long it stayed in the waiting queue. Make sure your program runs smoothly in a Linux environment and compiles without errors (if C is used, it must compile with gcc). Use of a library that implements Red-Black trees is not allowed....

Operating Systems Concepts - Java Programming
Assignment: The Impact of I/O on Application Performance In previous assignments, you used threads to improve the performance of a sort algorithm. Threads were initially applied in order to achieve processing concurrency in order to reduce the time required to sort data. This week’s readings highlighted various ways that I/O performance can impact the overall performance of an application or a system. The readings also identified specific principles that can be applied to improve the efficiency of I/O. For this Assignment, you will consider the I/O performed in the threaded sort Assignment from Week 2 and how the I/O contributes to the performance of the threaded sort. Applying the principles identified in this week’s reading, along with the concurrency control mechanisms from Week 3, you will revise the threaded sort application in an effort to improve the I/O performance in order to affect an overall performance improvement. To prepare: Evaluate the manner by which the threaded sort application performs I/O to retrieve the data to be sorted. Propose a strategy to improve the performance by applying one or more of the principles to improve the efficiency o...

Operating Systems Race condition
Semaphore is a type of inter-process communication mechanism used to facilitate process synchronisation. Write a C program, to illustrate the synchronisation problem (Race condition). Your code needs to clearly demonstrate the problem. The quality of your solution will base on the complexity of the scenario. The scenario requires minimal 5 processes and 3 resources (files). Discuss 1 solution for the problem. Present the code of your solution with the individual problem if possible. Clearly document the problem scenarios and the solution with a detail discussion....

Operating Systems- CPU Simulation - Threads -scheduling
Details of statistics to be output Default Mode - the total time required to execute the threads in all processes to completion - from arrival time of the first process to completion time of the last process - the average turnaround time of the processes - turnaround time is defined to be the time from submission to completion of a process - average turnaround time is the average of the turnaround time for all processes - the CPU utilization - CPU or processor utilization is defined to be the percent of time that the CPU is busy, i.e. is running a thread Note: all definitions taken from lecture notes Detailed Mode (-d flag) - the total time required to execute the threads in all the processes (see above) - the average turnaround time for all the processes (see above) - the CPU utilization (see above) - the arrival time, service time, I/O time, turnaround time and finish time for each thread - for each thread: - arrival time (you should be able to find this in the input file) - service time (how long was it in the CPU - once again the input file has all of the bursts ...
