Packing more than 786,000 processor cores, and putting out more than 8.5 petaflops of sustained computing performance, the Argonne National Lab's MIRA supercomputer is among the most powerful.
China has produced a supercomputer capable of 54.9 petaflops, more than twice the speed of any system in the U.S., according to a U.S. researcher who was in China last week and learned the details.
The U.S. Department of Energy's Oak Ridge National Laboratory on Monday completed the deployment of a 20-petaflop supercomputer called Titan, which the lab hopes will give the U.S. an edge over China and Japan in the race to build the world's fastest computers.
The global race for ever-faster supercomputers is getting a new entry.
The successful use of phishing emails to breach secure organizations like Oak Ridge National Laboratory and EMC's RSA security division is a stark reminder of the serious threat posed by a type of attack that was previously dismissed as low-tech.
The successful use of phishing emails to breach secure organizations like Oak Ridge National Laboratory and RSA are stark reminders of the serious threat posed by what some experts have dismissed as as a low-tech method of attack.
The Oak Ridge National Laboratory, home to one of the world's most powerful supercomputers, has been forced to shut down its email systems and all Internet access for employees since late last Friday, following a sophisticated cyberattack.
The U.S. is building two 20-petaflop supercomputers, many times more powerful than anything operating today, including China's new supercomputer, the Tianhe-1A, which is expected to be officially crowned next week as the world's fastest system.
