Cray XE6

[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.
