There are many different types of computers to meet our different needs. They are of different sizes, with different capabilities, for different purposes. Some are portable for ease of travel, while others are large enough to handle great amount of data and in formation.
Very expensive and are used for specialized applications that require immense amounts of mathematical calculations (weather forecasting, animated graphics, fluid dynamic calculations, nuclear energy research and petroleum exploration)
1.026 quadrillion calculations per second. The $133 million supercomputer achieved the milestone with the help of 12,960 "improved" Cell processors (yes, like those powering your PS3) and a smaller number of AMD Opteron processors
116,640 processor cores in total. Speed: 1.026 petaflops/sec
housed at U.S. Department of Energys Los Alamos National Laboratory in New Mexico
Use LINUX as its Operating System
DOE plans to use the computer for simulating how nuclear materials age
