Over the years, supercomputers have evolved to become faster, more powerful, and more efficient.
The Era Of Vector Processing
In the 1970s and 1980s, supercomputers began to use vector processing, which allowed them to perform calculations on large arrays of data simultaneously. This led to significant improvements in performance, and supercomputers like the Cray-1 and the Cyber 205 became the norm in scientific computing.
The Advent Of Parallel Processing
The 1990s saw the advent of parallel processing, where multiple processors were used to perform calculations simultaneously. This led to the development of massively parallel processors (MPPs) like the IBM SP2 and the Cray T3E. These machines were capable of performing calculations at speeds of tens of gigaflops (billions of floating-point operations per second).
The Current State Of Supercomputing
Today, supercomputers are more powerful than ever, with the fastest machines capable of performing calculations at speeds of hundreds of petaflops (quadrillions of floating-point operations per second). The current top-ranked supercomputer, the Summit, is located at the Oak Ridge National Laboratory in Tennessee, USA, and has a peak performance of over 200 petaflops.
