Summit and Sierra will operate at 150 petaflops and 100 petaflops respectively, which is the unit of measurement for supercomputer performance.
By comparison, the world's highest performing computer at present, the Tianhe-2 in China, performs at"just"55 petaflops. The first-ever supercomputer to reach 1 petaflop was built as recently as 2008.

The rate of performance developmenthe change in aggregate number of petaflops between Top500 listsad doubled each year.
just got clearance to begin acquisition of a supercomputer in the 1-3 petaflops range.
Other pieces of the ASCR roadmap include the mandate to maintain operations with>90 percent availability, deployment of a 10-40 petaflop upgrade at National Energy Research Scientific Computing Center (NERSC),
and continued preparations for 75-200 petaflop upgrades at Oak ridge Leadership Facility (ORLF) and Argonne Leadership Computing Facility (ALCF).
The listed peak performance of more than 150 petaflops would give Aurora at least 15 times more computing power than its predecessor, Mira,
the 10-petaflops IBM Blue Gene/Q that was installed in January 2012. Funding allocated to the ASCR program would also be directed to the following efforts:
and he expects them to achieve HPC-levels of performance up to an equivalent processing rate of 9 petaflops. He said that this was omparable to the 5th fastest computer in the world today.
Using Mira, the ALCF's 10-petaflops IBM Blue Gene/Q supercomputer, the researchers replicated the experimental conditions with large-scale molecular dynamics simulations aimed at understanding the underlying mechanisms of superlubricity at an atomistic level.
and expected to handle 100 petaflops each when completed in 2017. But breaking the exaflop barrier is complicated more than simply strapping ten Summits together.
