There are only 10 computers in the world with petaflops power—capable of calculating quadrillions of calculations in one second. According to the 37th edition of the Top500 List, the National Energy Research Scientific Computing Center’s (NERSC’s) Cray XE6 “Hopper” system is one of them.  

All of the systems on the TOP500 List are ranked on how fast they run Linpack, a benchmark application developed to solve a dense system of linear equations. With a Linpack benchmark performance of 1.054 petaflops, Hopper ranks number 8 among the most powerful systems in the world. The system has a theoretical peak performance of 1.29 petaflops.

The 37th edition of the Top500 List was announced this morning at the International Supercomputing Conference in Hamburg, Germany. Since its inception 18 years ago, the list has been a standard indicator of computing performance and architecture trends.
