- in C++ please create a Priority : -pre-emptive algorithm code: here are information that will help you Tasks: • Lab 4: Process management • Review Process management algorithms Definitions: (in terms for this lab not formal definitions) • Preemptive: When a new process arrives and has a higher priority than the current running process, Then the current running process is paused and put back in the waiting queue, and the new process starts executing. In most systems it will automatically interrupt the current running job when the new job arrives, however some systems use a predetermined interval (a certain number of time units), to check for new jobs. • Non preemptive: Take no action when a process with higher priority arrives,when a new process with a higher precedence arrives current running process need to finish first before the new process goes Oxford definition: Preempt – to take action in order to prevent (an anticipated event) from happening; forestall. • Metric: a metric is…Arguments for deep access over shallow access should be made from the viewpoint of an application programmer; performance should not be the focus of the argument.Resource requests may be made by those who have reached a halt owing to the finding of deadlocks in their processes.
- A system is made up of three processes that share five resources of the same kind that are all used in the same manner. Each process may be completed with a maximum of two resources. Are there any deadlocks in the system that can be demonstrated?sleep() is a system call? What are the steps that occur from the time when a call to sleep() is made by a process up to the time that it returns?Assignment description: When an operating system has been running for a while without reboot, and more it keeps allocating and de- allocating pages, the quicker the memory becomes fragmented. And the kernel may not always be able to defragment enough memory for a requested size on time. If that happens, applications may not be able to allocate larger contiguous chunks of memory even though there is enough free memory available. Being a system admin and considering the following scenario, discuss the current proposed solutions to solve the problem caused in this case and critically analyze the performance of the proposed solutions to solve the problem. Provide a report considering the following outlines. Scenario: In the following snapshot of running operating system, we can see that there is a free memory space equal to (55 KB). Assume that new process (process#07) needs to be run inside the memory and required 50 KB but the memory (fragment) is not contiguous. Assigned Space Assigned…
- COPY FROM CHEGG == DISLIKE AND REPORT Assume that a finite number of resources of a single resource type mustbe managed. Processes may ask for a number of these resources and will returnthem once finished. As an example, many commercial software packagesprovide a given number of licenses, indicating the number of applications thatmay run concurrently. When the application is started, the license count isdecremented. When the application is terminated, the license count isincremented. If all licenses are in use, requests to start the application aredenied. Such a request will be granted only when an existing license holderterminates the application and a license is returned. The following program segment is used to manage a finite number of instancesof an available resource. The maximum number of resources and the number ofavailable resources are declared as follows: #define MAX_RESOURCES 5 int available_resources = MAX_RESOURCES; /** When a process wishes to obtain a number of…When the parent process terminates, whether normally or unexpectedly, so do the offspring processes.An operating system has 3 user processes running in a set, each requiring 2 units of resource R. The minimum number of units of R such that no deadlocks will ever arise is:
- All deadlocks are caused by competing demands for resources.Critical Sections - Select all of the following statements that are true A critical section is a segment of code in which a process has write-access to data or resources that are shared with at least one other process. Every process waiting to enter a critical section must be allowed to enter it at some point. No eternal waiting must be possible. In a system consisting of n processes, a critical section protected by a mutex variable can be accessed by more than one process at a time. A process not executing in a critical section must not prevent other processes from entering the critical section. Critical sections must never contain data shared by multiple processes. O DELL WA deadlock occurs when a group of processes is stalled because one process is holding a resource and waiting for another process to obtain it. Consider the situation when two trains are approaching each other on the same track and there is only one track: once they are in front of each other, neither train can proceed. In operating systems, a similar scenario happens when two or more processes possess certain resources while waiting on resources owned by other processes (s). In the picture below, Process 1 is holding Resource 1 and waiting for Process 2 to acquire Resource 2, while Process 2 is waiting for Resource 1. Give an example of a realistic deadlock avoidance approach and describe the basic strategy behind it.
