Extremely fast data processing
-
oriented
computers.


Speed is measured in “FLOPS”.



For highly calculation
-
intensive tasks.



For “high performance computing”.



Aims at capability computing rather than

capacity computing.








Evolution of supercomputers

*Supercomputers were introduced in the 1960s .

*The supercomputers of the 1970s (Cray
-
1)



Used only a few processors.


Speed was 80MFlops.

*In1980s (Cray
-
2) was an



8 processor supercomputer.


Speed was 1.9MFlops.

*In the 1990s, machines with thousands of processors
began to appear.

*By the end of the 20th century supercomputers with
ten thousands processors.




Built by Cray Inc. at Oak Ridge laboratory.


Titan is an upgrade version of “Jaguar”.



Titan
also has more than 700 terabytes
of




memory.


Titan is
measured at 17.59 P
FLOPS.



Taken the no.1

slot
in top10 list
of
supercomputers.



20,000 trillion calculations each second


or
20PFLOPS.
