Supercomputers
perform large and complex mathematical computations in High speed.
|
Mainframe
computers act as a server, stores large database and serve a large number of
users simultaneously.
|
|
Invention:
|
The first successful Supercomputer was
invented by Seymour Cray in the year 1976, Cray 1.
|
IBM
invented the first Successful mainframe computer and is still a dominant
company for producing the mainframe computers.
|
|
Speed:
|
The supercomputer can execute billions of floating-point
operations in a second.
They can perform billions of instructions per
second (BIPS)
|
Mainframe
computers can execute millions of instructions simultaneously.
They
can perform millions of instructions per second (MIPS)
|
|
Size:
|
Supercomputers are the largest computers in
the world.
|
Mainframe
computers are also large computers but somewhat smaller than supercomputer.
|
|
Cost:
|
Supercomputers are the most expensive
computers.
|
Mainframe
computers are inexpensive compare to supercomputers.
|
|
Operating
system:
|
The modern supercomputers have Linux
operating system and derivative variants of Linux operating system.
|
Mainframe
computer has ability to run multiple operating system simultaneously.
|
|
Space:
|
It requires more space to Setup the computer
|
It
requires about 1000sq.ft space for setup the computer.
|
