NASA Langley CRAY-2 Supercomputer to Be Exhibited at Virginia
Air and Space Center
The CRAY-2 supercomputer, used for nearly a decade to simulate
flight for hundreds of research aircraft at NASAs Langley
Research Center, will now be housed at the Virginia Air and Space
Center for public display.
The move to the downtown Hampton museum is set for Thursday, May
The Virginia Air and Space Center is excited to be able to
display and interpret the supercomputer that has contributed to the
advancement of aeronautics and space research at NASA
Langley, said Kim Maher, Virginia Air and Space Center CEO
and executive director.
The machine was manufactured by worldwide supercomputer leader
Cray Research, Eagan, Minn. and was one of the most powerful
computers in the world when it was installed in 1988. The CRAY-2
has been replaced with one of the latest supercomputer systems from
Cray Research, which is even more powerful and more
The computer, named Voyager by researchers at NASA
Langley, will be displayed at the Virginia Air and Space Center,
which plans to build an exhibit around the computer. Cray Research
is donating additional exhibitry to the display as well as covering
moving costs for the May 30 event. The exhibit is expected to be
ready for visitors by early Fall.
The CRAY-2 has more memory than several hundred personal
an aggregate speed of more than 1,000 personal computers. It has
been used at NASA
Langley to simulate aerodynamic flow over flight vehicles, to
predict certain chemical reactions, to analyze and predict the flow
within rocket engines, to simulate the atmospheres of other planets
and to predict galactic collisions and interactions in space.
Voyager consists of a mainframe containing four processors and a
billion-byte memory, disk storage and its own liquid-immersion
cooling system. The large billion-byte central memory could hold 10
full sets of the World Book Encyclopedia and, using its incredible
speed, read all that information in a single second.
Computationally, it can achieve up to one billion arithmetic
operations per second called one gigaflop in the language of
supercomputers. How fast is a gigaflop? At that rate, Voyager can
sum up the Social Security numbers of all U.S. citizens in less
than 1/4 second. In less than one day, Voyager can do all the
computing that was done at NASA Langley during the entire year
The Virginia Air and Space Center is NASA Langleys
official visitor center. It is located at 600 Settlers
Landing Road in downtown Hampton. It includes interactive exhibits
on aeronautics and space as well as Virginia history. The museum
houses an IMAX® theater and offers special programs for
children and adults.
Cray Research, a subsidiary of Silicon Graphics, Inc., provides
the leading supercomputing tools and services to help solve
customers most challenging problems.
Photos, b-roll and interviews are available. For more
