Petascale computing

Cray XT5 Jaguar supercomputer, Oak Ridge Leadership Computing Facility

In computing, petascale refers to a computer system capable of reaching performance in excess of one petaflops, i.e. one quadrillion floating point operations per second. The standard benchmark tool is LINPACK and Top500.org is the organization which tracks the fastest supercomputers. Some uniquely specialized petascale computers do not rank on the Top500 list since they cannot run LINPACK. This makes comparisons to ordinary supercomputers hard.
