Parallel and Distributed Programming Using C++

"Hence, whatever parallel processes may be going on at a lower (neural) level, at the symbolic level the human mind is fundamentally a serial machine,...

A process is a unit of work created by the operating system. It is important to note that processes and programs are not necessarily equivalent....

The address space of a process is divided into three logical segments: text (program code), data and stack segments. Figure shows the logical layout of...

During a process' execution, the process's state changes. The state of the process is the current condition or status of the process. In the UNIX...

When a ready queue contains several processes, the scheduler must determine which process should be assigned to a processor first. The scheduler maintains data structures...

A context switch occurs when the use of the processor is switched from one process to another process. When a context switch occurs, the system...

To run any program the operating system must first create a process. When a new process is created, a new entry is placed in the...

When a process is terminated, the PCB is erased and the address space and resources used by the terminated process are deallocated. An exit code...

In order for a process to perform whatever task it is instructed to perform, it may need to write data to a file, send data...

Asynchronous processes execute independent of each other. Process A runs until completion without any regard to process B. Asynchronous processes may or may not have...

When considering dividing your program into multiple tasks, you are introducing concurrency into your program. In a single processor environment, concurrency is implemented with multitasking....

Concurrency in a C++ program is accomplished by factoring your program into either multiple processes or multiple threads. A process is a unit of work...
