Cray XT6

The Cray XT6 is an updated version of the Cray XT5 supercomputer, launched on 16 November 2009. The dual- or quad-core AMD Opteron 2000-series processors of the XT5 are replaced in the XT6 with eight- or 12-core Opteron 6100 processors, giving up to 2,304 cores per cabinet. The XT6 includes the same SeaStar2+ interconnect router as the XT5, which is used to provide a 3-dimensional torus network topology between nodes. Each XT6 node has two processor sockets, one SeaStar2+ router and either 32 or 64 GB of DDR3 SDRAM memory. Four nodes form one X6 compute blade.
