The new Titan supercomputer at Oak Ridge National Laboratory is now the world’s fastest, according to a Top 500 list released this morning.
A Cray XK7 system, Titan achieved 17.59 petaflops on a benchmark test, equal to more than 17,000 trillion calculations each second, a press release said.
Titan knocked Lawrence Livermore National Laboratory’s Sequoia from the No. 1 spot and into second place. Sequoia is an IBM BlueGene/Q system, and it was No. 1 in June with 16.32 petaflops.
Other systems in the Top 5 are Fujitsu’s K computer at the RIKEN Advanced Institute for Computational Science in Kobe, Japan (No. 3); a BlueGene/Q system named Mira at Argonne National Laboratory (No. 4); and a BlueGene/Q system named JUQUEEN at the Forschungszentrum Juelich in Germany (No. 5), which was upgraded and is now the most powerful system in Europe.
Titan is 10 times more powerful than Jaguar, ORNL’s last top supercomputer. It will be used for research in energy, climate change, engine efficiency, materials, and other disciplines.
Titan has 560,640 processors, including 261,632 NVIDIA K20x accelerator cores.
Sequoia has more than 1.5 million cores, and it is the first system with one million or more cores, the press release said.
The other new system in the Top 10 is Stampede, a Dell PowerEdge C8220 system installed at the Texas Advanced Computing Center at the University of Texas in Austin. It uses brand new Intel Xeon Phi processors to achieve its 2.6 petaflops, the press release said.
Today’s list was the 40th edition of the twice-yearly Top 500 list, and it was embargoed until 9 a.m. this morning. The results were scheduled to be announced during a supercomputing conference in Salt Lake City.
The press release said there are now 23 systems with petaflop performance on the latest list, just four-and-a-half years after the debut of Roadrunner, the world’s first petaflop supercomputer.
The TOP500 list is compiled by Hans Meuer of the University of Mannheim, Germany; Erich Strohmaier and Horst Simon of Lawrence Berkeley National Laboratory; and Jack Dongarra of the University of Tennessee, Knoxville.
