How fast was the Cray computer?
TECH STORY: The Cray-2 was a four processor vector architecture with a 256 million 64-bit memory (the largest central memory available on any computer) and 4.1 nanosecond clock speed. It reached a peak speed of 1.9 gigaflops.
How much memory did the Cray-2 have?
The CRAY-2 Common Memory consists of 128 memory banks with two million words per bank. Each memory bank occupies a circuit module. CRAY-2 logic networks are constructed of 16-gate array integrated circuits packaged in three-dimensional structures.
Is Cray-1 worlds first supercomputer?
Answer: The CDC 6600 from Control Data Corp., is generally recognized as the first supercomputer, according to Wikipedia. Built in 1964, it was designed by Seymour Cray, and ran at about 1 megaflop (a million floating point operations per second).
Are Cray computers still in use?
Seymour Cray later formed Cray Computer Corporation (CCC) in 1989, which went bankrupt in 1995. Cray Research was acquired by Silicon Graphics (SGI) in 1996….Cray.

According to Top500, which ranks computers around the world, as of November 2021, the Fugaku supercomputer located at RIKEN Centre for Computational Science in Kobe, Japan is the world’s fastest supercomputer.
Is Cray one a supercomputer?
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’s the Cray-2 immersed in?
Cray-2 CPU and cooling tower 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.

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.
How fast is Fugaku supercomputer?
442 petaflops
The Fugaku, jointly developed by Fujitsu and Japan’s Riken national research institute, attained a computing speed of 442 petaflops, or quadrillions of floating point operations per second, according to the supercomputer-ranking project TOP500.
How much memory does a Cray XMP have?
The X-MP initially supported 2 million 64-bit words (16 MB) of main memory in 16 banks, respectively. Memory bandwidth was significantly improved over the Cray-1—instead of one port for both reads and writes, there were now two read ports, one write port, and one dedicated to I/O.
What is the CERN Cray X-MP 48?
The CERN Cray X-MP/48 displayed at the EPFL in Switzerland. The Cray X-MP was a supercomputer designed, built and sold by Cray Research. It was announced in 1982 as the “cleaned up” successor to the 1975 Cray-1, and was the world’s fastest computer from 1983 to 1985 with a quad-processor system performance of 800 MFLOPS.
What is the difference between the Cray-1A and X-MP?
It housed up to four CPUs in a mainframe that was nearly identical in outside appearance to the Cray-1. The X-MP CPU had a faster 9.5 nanosecond clock cycle (105 MHz), compared to 12.5 ns for the Cray-1A. It was built from bipolar gate-array integrated circuits containing 16 emitter-coupled logic gates each.
How many processors are in a XMP?
In 1984, improved models of the X-MP were announced, consisting of one, two, and four-processor systems with 4 and 8 million word configurations. The top-end system was the X-MP/48, which contained four CPUs with a theoretical peak system performance of over 800 MFLOPS and 8 million words of memory.
