Cray announced a new supercomputer, the Cray XT4, that features 30,000 dual-core AMD Opteron processors:
According to the press release, the XT4 designed to easily and efficiently scale to a peak performance of more than one petaflops (1,000 trillion floating-point operations per second). Evolved from the Cray XT3 supercomputer, the Cray XT infrastructure provides a common, scalable environment for login, compilation, resource management, work scheduling and I/O. This environment also includes a unique globally shared, high-performance parallel file system, as well as network interfaces to other systems.
