Gene Amdahl Essay, Research Paper

Overview

One of the original architects of the

business mainframe computer, including IBM’s System/360 computer

line, Amdahl started the IBM-compatible market when he left IBM to found

Amdahl Corporation. Amdahl’s work has been called brilliant and genius

by his peers. The Times of London named him one of the "1,000 Makers

of the 20th Century" in 1991, and mainframe magazine Computerworld

considered Amdahl one of the 25 people "who changed the world."

He is the founder of four companies, Amdahl Corporation, Trilogy Systems

(now part of Elxsi Corporation), Andor Systems, and Commercial Data Servers

(CDS).

Early history

Gene Myron Amdahl was born in South Dakota in 1922. After serving two

years in the U.S. Navy during World War II, where he learned electronics,

and taking a course in computer programming, he received a bachelors degree

in engineering physics at South Dakota

State University in 1948. In 1952 he completed his doctorate in theoretical

physics at the University of Wisconsin,

where he designed his first computer, the Wisconsin Integrally Synchronized

Computer (WISC).

He began his career with IBM in 1952, and became the chief design engineer

of the IBM 704. In 1955, Amdahl worked with others to design the Datatron,

which led to a computer called the Stretch, and eventually became the

IBM 7030, a computer that used the new transistor technology. In 1956,

after just four short years with IBM, Amdahl became unhappy with the company

and quit. After five years of working for other computer companies, he

returned to IBM in 1960.

During the 1960s, Amdahl gained recognition as the principle architect

of IBM’s impressive System

360 series of mainframe computers. The IBM System 360 was based on

the Stretch, which Amdahl had worked on in 1955. The 360 series was one

of the greatest success stories in the computer industry and became the

main ingredient to IBM’s enormous profitability in the late 1960s.

Leaving IBM…again

Amdahl became an IBM Fellow and was able to pursue his own research projects.

In 1969, he was director of IBM’s

Advanced Computing Systems Laboratory in Menlo Park, California. He

recommended that the laboratory be shut down, which IBM did, and presented

his ideas about the internal barriers that prevented IBM from shooting

for the high end of computer development. Although his ideas were accepted,

IBM executives refused to change policies and Amdahl left IBM again.

In 1970, Amdahl formed his own company, Amdahl

Corporation, in Sunnyvale, California. His plan was to compete head-to-head

with IBM in the mainframe market. Most industry analysts considered this

to be career suicide and gave his start-up company very little chance

of surviving. But survive it did, and actually prospered. Instead of creating

a rival system to IBM, Amdahl created discounted computers that could

be substituted for name brand models and run the same software. Basically,

he designed the first computer clones, known then as "plug-to-plug

compatibles." Amdahl became the most celebrated entrepreneur in the

computer industry for awhile. The only major criticism that was raised

about Amdahl Corporation at the time was that Amdahl took start-up money

from Fujitsu Ltd. of Japan in exchange for American mainframe technology.

In 1975, Amdahl Corporation shipped its first computer, the Amdahl 470

V/6. Over the next few years, Amdahl and IBM leap-frogged each other with

faster, smaller, and cheaper computers. In 1979, Gene Amdahl began moving

away from Amdahl Corporation when he resigned his post as chairman. He

became chairman emeritus for less than a year, leaving Amdahl Corporation

in 1980 to found Trilogy Systems Corporation.

With the success of Amdahl Corporation, Amdahl had no trouble interesting

investors in this new company and easily raised $230 million in start-up

money. Again, his plan was to compete with IBM, and also Amdahl Corporation,

in the high-end mainframe computer market. In addition, Amdahl planned

to completely redesign the semiconductor chips that powered the computers.

His dream was to combine the functions of 100 separate chips onto one

superchip that would work faster and more efficiently than the multiple

chips.

Trilogy’s Misfortune

Unfortunately, Trilogy was hounded by disasters. Torrential rains delayed

construction of the chip plant, then invaded the air conditioning, destroying

the clean room atmosphere and all the chips currently being created. At

that point, Amdahl had spent one-third of the start-up money with nothing

to show for it. To save Trilogy, Amdahl spent the remainder of the money

to acquire Elxsi Corporation, a computer manufacturer, in 1985. The new

company continued to flou
