rdf:langString How did the Stretch compare to the Atlas, numbers anybody?

rdf:langString The term supercomputing arose in the late 1920s in the United States in response to the IBM tabulators at Columbia University. The CDC 6600, released in 1964, is sometimes considered the first supercomputer. However, some earlier computers were considered supercomputers for their day such as the 1960 UNIVAC LARC, the IBM 7030 Stretch, and the Manchester Atlas, both in 1962—all of which were of comparable power; and the 1954 IBM NORC. While the supercomputers of the 1980s used only a few processors, in the 1990s, machines with thousands of processors began to appear both in the United States and in Japan, setting new computational performance records. By the end of the 20th century, massively parallel supercomputers with thousands of "off-the-shelf" processors similar to those found in personal computers were constructed and broke through the teraflop computational barrier. Progress in the first decade of the 21st century was dramatic and supercomputers with over 60,000 processors appeared, reaching petaflop performance levels.
