What was Cray-1 used for?
development by Cray Research Inc. His company’s first supercomputer, the Cray-1, which came out in 1976, could perform 240 million calculations per second. It was used for large-scale scientific applications, such as simulating complex physical phenomena, and was sold to government and university laboratories.
What was the cost of the Cray-1 supercomputer?
Densely packed integrated circuits and a novel cooling system reflected Cray’s attention to “packaging and plumbing.” The Cray-1 was 10 times faster than competing machines. But speed came at a cost. It sold for up to $10M and drew 115 kW of power, enough to run about 10 homes.
Who bought Cray?
Hewlett Packard Enterprise
San Jose, Calif., September 25, 2019 – Hewlett Packard Enterprise (NYSE:HPE) today announced it has completed the acquisition of supercomputing leader Cray Inc., earlier than the original target date. HPE paid $35.00 per share, in a transaction valued at approximately $1.4 billion, net of cash.
Is Cray-1 is the first supercomputer?
The UNIVAC, which first appeared in 1951, was the first commercial computer produced in the United States. Seymour Cray left CDC in 1972 to start his own company. The first Cray-1 supercomputer was installed at Los Alamos National Laboratory in 1972.
Why did Cray 1 have the fastest scalar unit?
For Cray-1, he decided that in addition to fast vector processing, his design would also require excellent all-round scalar performance. That’s why Cray-1 has scalar and vector processing modes, that way when the machine switched modes, it would still be the fastest out there.

What does Cray mean?
crazy
(kreɪ ) or cray cray. adjective. slang. crazy; insane.
How many operation codes does the Cray-1 have?
The CRAY-1 executes 128 operation codes as either 16-bit (one parcel) or 32-bit (two-parcel) instructions. Operation codes provide for both scalar and vector processing. Floating point instructions provide for addition, subtraction, multiplication, and reciprocal approximation.
What makes a Cray 1 computer so powerful?
The CRAY-1 Computer System is a powerful general-purpose computer capable of extremely high processing rates. These rates are achieved by combining scalar and vector capabilities into a single central processor which is joined to a large, fast, bi-polar memory.
What was the cost of the Cray 1?
The Cray-1 was 10 times faster than competing machines. But speed came at a cost. It sold for up to $10M and drew 115 kW of power, enough to run about 10 homes. Over 60 miles of wire snaked through the Cray-1, with no segment longer than 3’ to minimize signal delays. This model shows how circuit boards were kept cool in the Cray-1.
Who was the designer of the Cray 1?
Cray-1. The Cray-1’s architect was Seymour Cray; the chief engineer was Cray Research co-founder Lester Davis. They would go on to design several new machines using the same basic concepts, and retained the performance crown into the 1990s.
