27.5 ns clock period (36 Mhz.)
3360 modules 120 miles of wire
36 Mega(fl)ops PEAK 60-bit words. Achieved via extensive pipelining of
9 Central processor’s functional units
Serial 1 operated 1/69-10/88 at LLNL
65 Kw Small core. 512 Kw Large core
15 Peripheral Processing Units
Notes:
Unlike most designers, the second design of a series seemed to be the right one. The 7600 design lasted longer than any other supercomputer design. It had the highest performance of any computer from its introduction in 1969 till the introduction of the Cray 1 in 1976.
It was upward compatible, but had more PPUs.
It had a peak of 30 times faster than the 6600. This was a good trick, because the clock was not quite 4 times faster. The increase in speed was achieved with pipelining in every functional unit.
