The initial model, the Cray-1A, weighed 10,500 pounds (4,800 kg) including the Freon refrigeration system. Configured with 1 million words of main memory, the machine and its power supplies consumed about 115 kW of power; [ 10 ] cooling …

The Cray-1 series of computers were manufactured from 1976 till 1983. About 60 of these machines were delivered to customer locations all over the world. At the time, they were the undisputed highest performing computers for scientific workloads. The Cray-1 system had the peripherals attached to the mainframe. The Cray-1S introduced the Input ...

The Cray-1 later became known as the Cray-1A, to differentiate it from the follow-on Cray-1S computer, which had an integrated I/O subsystem. The Cray-1A – serial number 3 – arrived at NCAR on July 11, 1977. The system cost $8.86 million ($7.9 million for the system, plus nearly $1 million for the disks). The supercomputer weighed 5.5 tons.

This paper describes the design and implementation of a state-of-the-art interactive vector graphics system connected to the CRAY-1 supercomputer. The primary design goal for this graphics system is that it support large hydrodynamic computer programs ...

Cray-1A. For five years, this was the world’s fastest computer. Each Cray-1 was hand wired and took nearly a year to assemble. Its unique vector-processing design suited it to many critical computational problems, such as cryptography, bomb simulation, and …

NCAR's second Cray-1A – serial number 14 – was configured the same as its first. It had a 12.5-nanosecond clock, eight 64-element vector registers, 1 million 64-bit words (8 megabytes) of high-speed memory, and 16 DD-19 high-speed disk drives, each with a capacity of 300 megabytes and a transfer rate of 4.5 megabytes per second.

The Cray-1 series of computers were manufactured from 1976 till 1983. There were three major variants, Cray-1A, Cray-1S and Cray-1M. About 60 of these machines were delivered to customer locations all over the world. At the time, they were the undisputed highest performing computers for scientific workloads.

2022年1月25日 · A Cray supercomputer that was in service at NCAR’s Mesa Lab facility from July 1977 to February 1989, then on public display through December 2021, is now in place at the NCAR-Wyoming Supercomputing Center (NWSC) in Cheyenne. The Cray-1A supercomputer being lowered by crane on delivery to the NCAR Mesa Lab.

For five years, this was the world’s fastest computer. Each Cray-1 was hand wired and took nearly a year to assemble. Its unique vector-processing design suited it to many critical computational problems, such as cryptography, bomb simulation, and aircraft design.

1977年11月4日 · 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.
