COMPUTERS



HIGH PERFORMANCE COMPUTERS

The Department of Meteorology has a number of scientists who use computing to forecast weather, to analyze climate, to visualize data -- in fact computers have become indispensable to modern-day scientists who confront relationships between data and computations.

In recent years there has been a revolution in the way computing is done. Serial Computers were used predominantly. This type of computer was developed in the middle of this century as the need for complex calculations and the manipulation of large data bases became evident.

However, in the last decade these serial computers have shown diminished capacity relative to the growth of data and complexity. A large part of the scientific (and commercial) community have moved over to Parallel Computers. Now the central processing units are reproduced many times in a single box (mainframe). The memory (distributed and shared) is also enlarged. This is often a cheap way to increase the capacity. The main drawback is the need for advanced software to drive the computer, and advanced peripherals to handle and visualize the large amount of data.


GROWTH IN SYSTEM PERFORMANCE

Research activities within the Department of Meteorology frequently require use of powerful workstations as well as remote supercomputers. The performance of these workstations is rapidly approaching that of the of the fastest supercomputers.
