Multiprocessing Essay -- essays research papers

parallel paradeing multiprocessing refers to a computer administrations ability to support more than one process or program at the same time. Multiprocessing operate systems enable several programs to stray coincidingly. UNIX is one of the most widely used multiprocessing systems, but on that point be many others, including OS/2 for high-end personal computers and Windows NT for work groups. Multiprocessing systems are much more complicated than single-process systems because the operating system moldiness allocate resources to competing processes in the most efficient manner. (IBM Dictionary of Computing, Tenth Edition, McGraw-Hill, (1994)).Types of MultiprocessingSymmetric multiprocessing refers to the processing of programs by multiple processors that share a common operating system, memory and data path. A single likeness of the operating system controls all processors. Symmetric multiprocessing units of this type are also referred to as divided up everything systems. Th ese systems usually do non go 16 processors.(Image courtesy of Sequent Manufacturing)The most common uses of these types of systems are commercialised servers of web applications such used in on line commerce. The advantages of this item configuration are that they can be easily upgraded by the do-gooder of more processors. These processors are available to execute any of the given processes as soon as the operating system recognizes and configures the tonic hardware. However, the limitations of such a configuration are that with shared memory, there is a strong stress on data manipulation. As each processor competes for a special(a) amount of shared memory, this limits the speed and up-gradability of such a system. Manufacturers must bank on the development of faster, higher capacity memory to overcome this disadvantage. currently symmetric multiprocessing computers can address up to 14 gigabytes of sensible memory and approximately 2 terabytes of storage. (Sequent Manuf acturing Inc., white papers 1998)Parallel touchParallel processing is a form of information processing that emphasizes the concurrent manipulation of data elements belonging to one or more process solving a single problem. It is also referred to as a shared nothing system.
