what is a problem with using a spin lock instead of a mutex? a. small critical sections that are executed repeatedly by the same thread, can cause problems in the CPU itself due to centrifugal force b. if the critical section is large, CPU time can be wasted when two threads try to execute the critical section at the same time c. spin locks are always better than mutexes if you don’t need condition variables d. spin locks are not...

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...

How do I do this C++ in a Unix Environment assignment Given dot1m.c 1. The program (dot1m.c) uses mutex to lock and unlock the shared resource (dotstr.sum) for access control as shown below. pthread_mutex_lock (&mutexsum); dotstr.sum += mysum; printf("Thread %ld did %d to %d: mysum=%f global sum=%f\n", offset,start,end,mysum,dotstr.sum); pthread_mutex_unlock (&mutexsum); 2. Modify dot1m.c program to use reader-writer lock (instead of mutex). Replace the codes (for mutex) by the codes (for reader-writer lock). To initialize reader-writer lock, pthread_rwlock_initializer. At the end,...

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,...

1. a. (True/False) A single process can have more than 2 threads. d. (True/False) Every thread has its own virtual address space. f. (True/False) A process may have 0 threads. g. (True/False) Threads belonging to separate processes cannot share memory. h. (True/False) Like function ‘fork’ in the process API, function ‘pthread_create’ creates a clone of the current thread. i. (True/False) Condition variables can be implemented using locks as the only available synchronization primitive. j. (True/False) Dekker’s mutual exclusion algorithm does...
