The CDC 6600 of 1964 generally is considered as the first "Supercomputer". It was unsurpassed in its speed until introduction of the CDC 7600 in 1968, which in turn was undefeated until the arrival of the Cray-1 in 1976. Further Cray Research vector machines were based upon the Cray-1 architecture. Moderate parallelism (2-64 vector processors) was added. This family continued to hold the performance leadership until arrival of massively parallel machines in the 1990s. The basic design principles of these machines not only enabled their offspring to remain in the pole position for almost thirty years, but also have influenced essentially any modern data processing device.
