Chinese supercomputer Nebulae ranks second in the 35th edition of the Top 500 list of supercomputers, with its theoretical peak performance of nearly 3 petaflops.

The Nebulae is built from a Dawning TC3600 Blade system with Intel X5650 processors and NVidia Tesla C2050 GPUs.

As the fastest system worldwide in terms of theoretical peak performance, and using  the LINPACK benchmark, the Nebulae performs at 1.3 petaflops.

The supercomputer is now located at the newly-built National Supercomputing Centre in Shenzhen, China.

he Nebulae achieved its position in part due to its NVidia GPU accelerators, and it reported the highest ever theoretical peak capability in the history of the list.

Tianhe-1, another Chinese supercomputer, was ranked No.7.

According to the new list, Jaguar from the US held on to the No.1 spot with a record of 1.75 petaflops performance speed.

Roadrunner at Los Alamos, which became the first ever petaflop system in June 2008, dropped to No. 3 with a performance of 1.04 petaflops.

At No. 5 is the most powerful system in Europe, Jugene from Germany. It achieved 825.5 teraflops on the Linpack benchmark.

The performances of Nebulae and Tianhe-1 were enough to catapult China into the No.2 spot of installed performance, with 9.2 percent, ahead of several European countries, but still clearly behind the United States, with 55.4 percent.

The newest version of the Top 500 list, which is issued bi-annually, was formally presented on June 31, at the International Supercomputer Conference held in Hamburg, Germany.
