Nebulae, Jaguar...these are not constellations or animals ..but Supercomputers

Yes these supercomputers are the most powerful computers with an amazing processing speed calculated in FLOP's i.e Floating Point OPerations per second. The word that was new to me was PetaFlops.


Why are these supercomputers called supercomputers ?
It is because the Supercomputer can perform a trillion tasks per second. Their performance is measured in PetaFlops->Now, thats the word for the day.


The Rank 1 Supercomputer in the world ;
The top system is Cray's Jaguar supercomputer at the U.S. Department of Energy's Oak Ridge National Laboratory, which is a 1.76 petaflop system.
The Rank 2 Supercomputer in the world ;
The Nebulae, a 1.27 petaflop system, China


Now when we say 1.76 PetaFlops or 1.27 Petaflops what do we exactly mean? How big is this measure?


1 PetaFlop = thousand trillion floating point operations per second.


So you can now imagine how fast the super computers work!
