The Cray XT5 is an updated version of the Cray XT4 supercomputer, launched on November 6, 2007. It includes a faster version of the XT4's SeaStar2 interconnect router called SeaStar2+, and can be configured either with XT4 compute blades, which have four dual-core AMD Opteron processor sockets, or XT5 blades, with eight sockets supporting dual or quad-core Opterons. The XT5 uses a 3-dimensional torus network topology.
