The Cray XE6 (codenamed Baker during development) is an enhanced version of the Cray XT6 supercomputer, officially announced on 25 May 2010.[1] The XE6 uses the same computer blade found in the XT6, with eight- or 12-core Opteron 6100 processors giving up to 3,072 cores per cabinet,[2] but replaces the SeaStar2+ interconnect router used in the Cray XT5 and XT6 with the faster and more scalable Gemini router ASIC. This is used to provide a 3-dimensional torus network topology between nodes. Each XE6 node has two processor sockets and either 32 or 64 GB of DDR3 SDRAM memory. Two nodes share one Gemini router ASIC.[2]

The XE6 runs the Cray Linux Environment version 3. This incorporates SUSE Linux Enterprise Server and Cray's Compute Node Linux.[2]
