Computer organization for array processing

In spite of recent advances in computer speeds, there are still problems which make even greater demands on computer capabilities. One such problem is that of global weather prediction. Here a three-dimensional grid covering the entire world must be stepped along through relatively short periods of simulated time to produce a forecast in a reasonable amount of real time. This type of problem with its demand for increased speed in processing large arrays of data illustrates the applicability of a computer designed specifically for array processing.
