But the Cray-2 supercomputer, though smaller than the Cray-1, ran 12 times faster. It computed in one second what would have taken ENIAC several months. The Cray-2 took nine years to develop.

technology used by the CRAY-2 is a breakthrough in the design of cooling systems for large-scale computers. It places the cooling medium in direct contact with the components to be cooled, thus efficiently reducing and stabilizing the operating temperature and increasing system reliability. The CRAY-2 mainframe operates in a cabinet filled

The Cray-2's unusual cooling scheme immersed dense stacks of circuit boards in a special non-conductive liquid called Fluorinert™, which in turn was cooled in the tank at the right. This machine was used to simulate nuclear fusion.

Cray Research, Inc. was the world leader in supercomputing for more than two decades. The company reflected Cray’s emphasis on simple design and small, focused development teams. The results validated his approach.

There are four separate color images of the Cray computer on this print. The top left image shows the Cray with red panels at the bottom and a clear top portion that shows the interior of the computer.

The Cray-2 design resembles a large aquarium, with its circuit boards cooled by immersion in a special fluid called Fluorinert.

Rollwagen, an electrical engineer and businessman, became CEO in 1980. He led Cray Research, Inc. through its most successful period, but also through its decline.

The simple architecture of the Cray-2 made it very powerful and easy to program for certain applications.
