Evolution of Supercomputers
Many current desktop computers are actually faster than the first supercomputer, the Cray-1, which was developed by Cray Research in the mid-1970s. The Cray-1 was capable of computing at 167 petaflops by using a form of supercomputing called vector processing , which consists of rapid execution of instructions in a pipelined fashion. Contemporary vector processing supercomputers are much faster than the Cray-1, but an ultimately faster method of supercomputing was introduced in the mid-1980s: parallel processing . Applications that use parallel processing are able to solve computational problems by simultaneously using multiple processors.
