Rather it signifies the fastest computers available at any given time. In mid 2011, the fastest supercomputers boasted speeds exceeding one petaflop, or one thousand trillion floating point operations per second. Super computer systems are fast but extraordinarily expensive so they are generally utilized by massive organizations to execute computationally demanding tasks involving large data sets. Super computer systems sometimes run navy and scientific functions.
