- From the Dec 18, 1992 issue of the Langley Researcher:
-
- A powerful computer known affectionately as "R" has been put
- out to pasture after 16 years of service-- an eternity in the quickly
- changing computer world.
- The Control Data Cyber 170 series model 175 was decommissioned
- November 20 at a ceremony that featured speeches and poems lauding the
- aged machine.
- The computer had been used by the Analysis and Computation
- Division (ACD) for real-time flight simulation and analytical batch
- processing.
- The batch computations ranged form small jobs of a few seconds
- to extremely complex work requiring many machine hours per run.
- The flight simulation applications were run concurrently, with
- each job typically requiring a full set of complex aerodynamic computations
- repeated over 30 times each second.
- The "R" machine was put into service in 1976 along with a similar
- computer called "T" that was retired in June. They are being replaced
- by a Convex C3230 "Agena" and a Convex C3850 supercomputer "Gemini."
- The new system is about 20 times faster than the old one, with
- about 100 times more memory, said Jeff Cleveland, of ACD's Computer
- Systems Branch.
- "R" is being sold for parts, Cleveland added. "It cost us three
- million bucks," he said, "and we're selling it for $3,000."
