- Pre-emptive vs noND-pre-emptive scheduling should be distinguished.We define an m-section to be a sequence of code that can be run concurrently by maximum m threads. There are n threads in a process. Each thread executes a thread function doWork() that calls doCriticalWork() in an infinite loop. Function doCriticalWork() requires that at most m threads run it concurrently. The enter() and leave() functions are used to limit the number of threads within the m- section to a maximum of m and are the only functions that deal with synchronization. The pseudo-code algorithm for the thread function is this: void doWork(...) { while (true) { enter(...); I/ limit access to m threads Il execute m-section doCriticalWork(.); Il run by max. m threads leave(.); I/ leave m-section Il do more work Function enter() returns immediately only if there are less than m threads in the m-section. Otherwise, the calling thread will be blocked. A thread calls leave() to indicate it has finished the m-section. If there was another thread blocked (in enter() waiting to enter the…Write an ALP program for ARM Cortex M3/4 to perform the following(1) SVC is to be called from an application task running at Thread unprivileged mode.(2) Two parameters are passed to the handler via R1, R2.(3) If the SVC number is last 3 digits of your Student ID (0 to 255) or last 2 digits of your Student ID (if last 3-digits of Student ID > 255), then the addition of the data in R1, R2 should be performed and after that return and resume application task.(4) If the SVC number is not your Student ID (3 or 2 digits), then return and resume application task.Give suitable screen shots of the KEIL IDE-in debug mode to demonstrate the desired outputs.

- Suresh and Ramesh started creating an application where it requires to do some mathematical operations.They are going to deploy it in a server. They wanted to do simultaneous execution of multiple parts ofprograms to utilize CPU time. They decided to create 2 separate threads for operations: num**2 andsqrt(num) with sleep of 100ms each.Write a program containing two threads and each thread should have a sleep of 100 ms. One thread is forcalculating the square of the elements in the array and other is for square roots.Trace the output in the threads only. Use Exception handling to handle and trace the interruptions if they occur.Input: An array. Can use static data. Preferably try to use run() and start().Output:"Thread 1"+ square(num)"Thread 2"+ square root(num)likewise to distinguish the thread status10 Write a C program that creates five threads (in addition to the initial thread) and makes each execute a function task(void * i) for i integer ranging from 1 to 5. in this function, make an empty loop of 10000 steps, then display of the i number and the thread id on the screen. The initial thread will also perform the display. Check on this example that: — The use of the exit() function in one of the threads of the process leads to the termination of all the threads. — The termination of the initial thread leads to the release of all the resources, therefore the termination of all the threads of the process. How to avoid this premature termination?you are tasked with analyzing an algorithm which schedulea processes in a multiprogramming system. You are working with a computer that has two CPUs, each CPU having two threads (hyperthreading). You are studying a scenario with three processes: P0, P1, & P2., with run times of 5, 10, & 20 msecs, respectively. All 3 programs are 100% CPU bound, don't block, and always run in the CPU it's assigned to. How long will it take for these programs to complete execution. Show three different possible outcomes (and assigned process to processor, 3 different combinations and resulting total time for all three to complete)
- design a java program that implements thread priority based on setPriority() method using different level of priority for two threads .Both these threads donot run on preemptive platform in the same way.Thus,prioritize the threads by running each thread for few seconds.After this main thread stops this thread.Moreover, the program should display the no of times each thread made it through the loop is displayedLab 4 Directions Write a C program called threadcircuit to run on ocelot which will provide a multithreaded solution to the circuit-satisfiability problem which will compute for what combinations of input values will the circuit output the value 1. This is the sequential solution, which is also attached. You should create 6 threads and divide the 65,536 test cases among them. For example, if p=6, each thread would be responsible for roughly 65,536/6 number of iterations (if it's not divisible, some threads can end up with one more iteration than the others). The test cases must be allocated in a cyclic fashion one by one. #include <stdio.h>#include <sys/time.h>/* Return 1 if 'i'th bit of 'n' is 1; 0 otherwise */#define EXTRACT_BIT(n,i) ((n&(1<<i))?1:0)int check_circuit (int z) { int v[16]; /* Each element is a bit of z */ int i; for (i = 0; i < 16; i++) v[i] = EXTRACT_BIT(z,i); if ((v[0] || v[1]) && (!v[1] || !v[3]) && (v[2] || v[3])…1. _is simply a priority algorithm where the priority (p) is the inverse of the (predicted) next CPU burst. 2. The implementation of the FCFS policy is easily managed with a 3. The objective of_ is to switch the CPU among processes. 4. A heavyweight process has a 5. When a request is made, rather than the server creates a new thread to service the request and resume listening for additional requests. 6. "Instructions are being executed", this state is called includes the list of 1/0 devices allocated to the process. 7. 8. it would be able to service only one client at a time, and a client might have to wait a very long time for its request.
- A deadlock condition can occur in concurrent code if two or more threads each hold a resource and are waiting for another thread to release a resource they need to proceed. Question 10 options: True FalseConsider an ARMv8 computer that is running more than one thread of execution. The computer has certain resources that must not be accessed or modified by different threads at the same time. These resources could be peripheral devices or memory buffers and data structures that are accessible by any threads. This type of concurrency control is a general computer science problem. It is possible to protect a shared resource by implementing a lock function, which allows a thread request ownership of the resource. An unlock function is necessary to allow software to release the lock. A simple lock system could be implemented using a variable in memory that can contain one of two values, LOCKED and, UNLOCKED. The action is to first read the value from memory, and if the lock is UNLOCKED then the value can be updated to LOCKED and written back to memory. This method is vulnerable to another thread modifying the value in memory in between the first read and the write-back of the new value. The…Two threads are at race condition to increment a global variable count from 0-10. But for the count to have values between(included) 3 and 6 only one thread should increment its value while other should be at sleep. Write the c code for this problem.
