	Cyber 205
		The Cyber 205 system included: CPU with 20-nanosecond clock cycle, 2 vector pipelines, 32 megabytes of central memory and 7.2 gigabytes of on-line disk storage.
		The Cyber 205 had a theoretical peak performance of 200 MFLOPS, and a LINPACK rating of 17 MFLOPS.
		Communications between the Cyber 205, its peripherals, and various front-end mainframes were handled by a Loosely-Coupled Network (LCN) consisting of four separate coaxial trunks.

	ETA Systems - Wikipedia, the free encyclopedia
		Seymour Cray left CDC in the early 1970s when they refused to continue funding of his CDC 8600 project.
		It was essentially a modernized version of the CDC Cyber-205 computer, and deliberately kept compatiblility with it.
		Like the Cyber series, the ETA-10 did not use vector registers as in the Cray machines, but instead used pipelined memory operations to a high-bandwidth main memory.

	Supercomputer - Wikipedia, the free encyclopedia
		Supercomputers introduced in the 1960s were designed primarily by Seymour Cray at Control Data Corporation (CDC), and led the market into the 1970s until Cray left to form his own company, Cray Research.
		CDC's early machines were simply very fast scalar processors, some ten times the speed of the fastest machines offered by other companies.
		In the 1970s most supercomputers were dedicated to running a vector processor, and many of the newer players developed their own such processors at a lower price to enter the market.

	ETA Systems
		Unlike Cray Research, however, ETA never escaped the orbit of its parent company, and was closed by CDC in April 1989 after having installed about 25 systems.
		The ETA-10 was designed to be instruction-set compatible with the CDC Cyber 205.
		Like its ancestors in the CDC Cyber series, the ETA-10 was a vector machine without explicit vector registers, relying on pipelined memory operations to a high-bandwidth memory hierarchy.

		The vector capability of the CDC CYBER 205 is exploited to significantly reduce the time over that used on a scalar machine.
		The code will only execute on CDC CYBER 200 computers due A to usage of extensions of FORTRAN which amount to syntax for vector operations.

		Though not cutting-edge technology (ours was the next to last one built), the Cyber 205 was a consistent performer, and provided a reasonably stable supercomputing environment for researchers at FSU and around the country.
		This process required the compilation of source code and subsequent loading of object code on the Cyber 205 to create a controllee, or executable file, which was then transferred to the ETA via an Apollo workstation.
		In retrospect, however, the continued use of the Cyber 205 abstract architecture, with memory-to-memory long vector pipelines supplemented by a somewhat underpowered scalar processor, did not seem justified with respect to the lack of wide acceptance of the earlier 205.

	1.2.1 Background to the Unified Model
		The models ran on a CDC CYBER 205 which was due to be replaced by an ETA systems platform during 1989.
		Significant effort was expended in adapting the code of each model to run on the new platform, but this work was suspended when the manufacturing company was wound up and a new vendor had to be found.
		The lifetime of the CYBER was extended and development of the CYBER models frozen; a Cray Systems YMP with 8 vector processors was procured with a Unix based operating system and the machine arrived in January 1990.

	Supercomputers
		Key to the ASC's design was a single high-speed shared memory, which was accessed by a number of processors and channel controllers, in a fashion similar to Seymore Cray's groundbreaking CDC 6600.
		One key difference was that the CPU was split in two, the operating system ran on the "peripheral processor", while applications were run on the dedicated, slave, ALU, which they referred to as "the" CPU.
		Others entered the arena in supercomputing after CDC and Cray showed it was possible to create supers.

		In July 1957, CDC was incorporated based on an initial financing by the sale of 615,000 shares of stock to the public for $1.00 per share.
		Thus, in their day, the ENIAC, EDVAC, ERA 1103, CDC 6600, CDC 7600, CRAY 1, and CDC Cyber 205 could all be legitimately called supercomputers.
		In the early seventies, CDC also initiated the Plato computerbased education system in cooperation with the University of Illinois and the National Science Foundation, because computer-based education is the most significant application area.

		In many cases the vector unit cannot take advantage of it and execution speed may even be unfavorably affected because of frequent cache overflow.
		Although vectorprocessors have existed that loaded their operands directly from memory and stored the results again immediately in memory (CDC Cyber 205, ETA-10), all present-day vectorprocessors use vector registers.
		This usually does not impair the speed of operations while providing much more flexibility in gathering operands and manipulation with intermediate results.
