| | Computer multitasking - Wikipedia, the free encyclopedia |
| | Each user wanted to see his program running as if it was the only program in the computer. | | | Several different programs were loaded in the computer memory, and the first one began to run. | | | In time-sharing systems, the running task is required to relinquish the CPU, either voluntarily or by an external event such as a hardware interrupt. |

| | Efficient use of computer time was the impetus for the development of multiprogramming systems. | | | Batch systems were developed prior to multiprogramming as a means of increasing efficiency of computer time use. | | | In contrast to a multiprogramming system, a batch system executes its jobs sequentially, and might be referred to as a "monoprogramming" system (though certain batch systems have monitor programs, which might classify them loosely as multiprogramming systems). |

| | Multiprogramming operating system is operating system which, in addition to supporting multiple concurrent process (several processes in execution states simultaneously) allows the instruction and data from two or more separate processes to reside in primary memory simultaneously. | | | In a multiprogramming system, more than one program resides in the computer's main memory. | | | Therefore, multitasking operation is one of the mechanism that multiprogramming operating system employs in managing the totality of computer related resources like CPU, memory and I/O devices. |

| | jGuru: What is the difference between multithreading and multitasking? What about multiprogramming? Multiprocessing? |
| | Multiprogramming is a method of running several different programs in a computer apparently at the same time. | | | Multiprogramming is essentially a synonym for multitasking (though multitasking connotes sharing more resources than just the CPU, and is the more popular term). | | | Usually on a mainframe - the computer has a number of programs loaded into memory and the operating system switches quickly between them, processing a little bit of each one in turn. |

| | CS322: Memory Management |
| | Some of the earliest multiprogramming systems maintained only one process in main memory at a time (along with the monitor, of course.) When a process switch occurred, it was necessary to swap processes wholesale between main memory and backing storage such as drum, disk, or extended core storage. | | | Early multiprogramming systems (and some in use today) emulated this model by giving each process a contiguous region of memory, bounded on either side by the monitor, another process, and/or physical end of memory. | | | An example is IBM MFT (Multiprogramming with a Fixed number of Tasks) which was part of OS/360. |

| | Multiprogramming |
| | The answers to several questions are important to implementing an efficient virtual memory system in a multiprogrammed environment. | | | In order to use the multiprogramming concept, processes must be loaded into independent sections or partitions of memory. | | | Advancements in operating systems led to computers that load several independent processes into memory and switch the CPU from one job to another when the first becomes blocked while waiting for servicing by another device. |

| | Yet, typical multiprograms employing message passing over bounded or unbounded channels can be encoded in Seuss by declaring the processes and channels as the components of a program; similarly, shared memory multiprograms can be encoded by having processes and memories as components. | | | We view multiprogramming as a way to orchestrate the executions of these sequential programs, by specifying the conditions under which each program is to be executed. | | | Typically, several sequential programs will execute simultaneously; yet, we can guarantee that their executions are non-interfering, and hence, each program may be regarded as atomic. |

| | CITIDEL: Viewing 'On the applicability of using multiprogramming level distributions' |
| | The multiprogramming level is a random variable with an associated distribution. | | | However, in many actual systems, closed and open models are both inappropriate since the multiprogramming level is neither fixed nor governed by an outside arrival process. In an actual system., the multiprogramming level varies due to features such as task spawning, killing, blocking, parallel processing, and/or simultaneous resource possession. | | | A computer system's workload is represented by its multiprogramming level, which is defined as the number of tasks (jobs, customers) which actively compete for resources within the system. |

| | And still even if you could hook only one interactive program to a terminal, it would be a shame to let the processor you paid so dearly run billions of cycles idle each second, therefore you'd optimize your investment connecting a lot of terminals to the computer and use time-sharing multiprogramming amongst all the users. | | | Even if I'm in a GUI and I have a dozen programs open, if they're all editor programs chances are only one of them is doing any real work at any given time. | | | Even if you could hook only one interactive program to the terminal, you would still want to run several batch programs in background in multiprogramming. |

| | Multiprogramming Effects |
| | Although a cyclic implementation performs better in the absence of multiprogramming, it often performs worse in the presence of multiprogramming. | | | For example, several experiments indicated that the execution time of Cholesky factorization with a cyclic data distribution is more sensitive to multiprogramming than an implementation using a blocked data distribution. | | | On a multiprogrammed machine, the additional communication and synchronization create more opportunities for multiprogramming to context switch a process that must synchronize with another, which increases waiting time on another processor. |
