Answer 9:
Priority inversion is a problem.Where a low priority process acquiring a resource that a high priority process needs, and then being preempted by a medium priority process, so the high priority process is blocked on the resource while the medium priority one finishes
To Solve this we have several protocols:
Priority Ceiling
Priority Inheritance

Write a multi-threaded program with Semaphores as counters and pthread_mutex_t mutex to solve the producer-consumer problem: A bounded buffer is simply a global integer array of size N (2) which can be accessed by multiple threads. • Create two types of threads - Producer (2) and Consumer (2). Producers will write to the buffer, and the consumers will read the buffer. In this scenario,...

TRUE-FALSE Basic synchronization principles and multithreading 1. Java user threads can implement both busy-waiting and no-busy-waiting policy. 2. Priority inversion avoids deadlocks. 3. Spinlock mutex can be used as an adaptive mutex. 4. Java RTE can be blocked for Input/Output operation. 5. Interrupted user thread, which executes a method in a monitor, must be rolled back to undo any changes it performed. 6. The synchronization primitive by disabling interrupts can be used by an application program. 7. Bounded-waiting requirement is...

Description In this homework, you are asked to implement a multithreaded program that will allow us to measure the performance (i.e, CPU utilization, Throughput, Turnaround time, and Waiting time in Ready Queue) of the four basic CPU scheduling algorithms (namely, FIFO, SJE PR, and RR). Your program will be emulating/simulating the processes whose priority, sequence of CPU burst time(ms) and I'O burst time(ms) will be given in an input file. Assume that all scheduling algorithms except RR will be non-preemptive,...

This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects.
