New Cray XT4 Opteron-Based Supercomputer with one petaflop performance

An upgrade to the Cray XT3 supercomputer at Oak Ridge National Laboratory aims at a supercomputer with AMD's quad-core processors with a peak performance of one petaflop.

Currently Cray XT4 supercomputer runs dual-core opteron processors and will be upgraded with quad-core processors when the chip technology is released.

The performance of the machine has not yet been defined practically when running with actual research codes. It has a sophisticated design, which uses as many as 30,000 dual-core Opteron processors coupled with its own interconnection chip, this will provide added scalability and performance.

For better performance measurement, the company has designed a sustained system performance benchmark suite (SSP).

This powerful design is a breakthrough in real-world scientific and engineering problems that will ultimately have a major impact on society.
