Реферат: The fastest computers of the world
The fastest computers of theworld.
One of sensations presently is the supercomputer.They can look as a small case, or a curbstonenear a table.
Business andits requirementsforcalculations grow, together with it the supercomputer develops also.
It differs from the usual computer in additional processorsand hard disks. For increasingof working frequency special processorsare used.
They are executed on the logic circuits. The style programmingis determined by use of group parallelof processors. We can divide given on a portionbetween different processors. Each of processorcarries out a part of work together with others.During process they exchange the data. Modern supercomputers are expansionly.You can add processors for acceleration of calculation.For the reference to external memory, the processor should use the circuit oftransfer of the information.
The new computers help the petroleum companies toestimate possible reserves of petroleum and gas, by data processing. They cansimulate outflow of raw material from tanks.
The manufacturers of automobiles can imitatean impact of the prototypeabout a wall. It allows to let out more reliable and powerful production.
The supercomputers are used at telephone stations.The orders of steel to be processed quickly. Consultator, which serves the buyers, enters the applicationsfor a line. They act on processing or immediately, or periodicaly.
The decisive triumph, can, consists in penetrationof multiprocessor architecture into all personal computers.
