Exam 6: Concurrent Processes

The master/slave configuration is an symmetric multiprocessing system.

Each active thread in a process shares the ____ and the resources allocated to its process.

In parallel computations, mutual exclusion is achieved automatically because each operation is handled in order, one at a time.

The symmetric configuration is best implemented if the processors are all of the same type.

The problem of masters and slaves arises when two types of processes need to access a shared resource such as a file or database.

____ sets the process's process control block (PCB) to the blocked state and links it to the queue of processes waiting to enter this particular critical region.

Implied parallelism includes automatic detection by the compiler of instructions that can be performed in parallel.

The classic problem of producers and consumers is one in which one process produces some data that another process consumes later.

In a symmetric configuration, processor scheduling is ____.

A thread transitions from RUNNING to ____ when it has to wait for an event outside its control to occur.

The success of process synchronization hinges on the capability of the operating system to make a resource available to other processes while it is being used by one of them.

The WAIT and SIGNAL operations must be issued at the same time.

Automatic detection by the compiler of instructions that can be performed in parallel is called ____.

In a loosely coupled system, a job may move from one processor to another during execution.

Operations on semaphore s enforce the concept of ____, which is necessary to avoid having two operations attempt to execute at the same time.

When using a semaphore, a value of ____ indicates that a critical region is in use.

The only reason for multiprocessing is to increase computer power.

Thread Information Blocks contain basic information about a thread such as its ID, state, and a pointer to the process that created it.

____ proposed a solution to the readers and writers problem that did not result in starvation for readers or writers.

Parallel processing is also called ____.
