Supercomputing

The kings of data processing

Single unit supercomputers
Superconductors
 Semiconductors
 Extensions of the “Dinosaurs of Computing”


Tandem Supercomputers
Many Desktops units tied together in parallel
 Many of the same capabilities
 Lower cost

This supercomputer dubbed “Blue Horizon” boasts 1152 processors and
peak processing power of 1.7 terraflops which is 1.7 trillion operations
per second. This type of computing power has a price tag of over 50
million dollars.
The Internet: Computers United

Origins
Developed for military applications during the 1960’s
 Early 1970’



Colleges started forming networks to send data to one
another.
Email: 1972

A new way to send data developed by Ray Tomlinson. By
1973 more than 75% of all traffic on these networks was
email.
Internet: Computers United

To the Present
Many technologies were developed to enable these
computers to “talk”
 The “Big Bang” of the internet started when the
WWW protocol was released by CERN in 1991
 Communication and Data Gathering on a scale
never seen before.
