Engineers of Cray are powering up for the first time worldwide a Cray XK6 delivered to a customer. CSCS was the first supercomputing centre signing a contract with Cray for the delivery of a Cray XK6 with 2816 cores, 176 GPU for a total of 137 TF. CSCS nicknamed the supercomputer “Tödi” after the name of a Swiss mountain.
The Cray XK6 supercomputer combines Cray’s Gemini interconnect, AMD’s multi-core scalar processors and NVIDIA’s many-core GPU processors. Shortly the Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) signed a contract with Cray to upgrade the Cray XT5 supercomputer nicknamed “Jaguar” to a new Cray XK6 supercomputer, which will be nicknamed “Titan.” When completed, the Titan system will have a peak performance between 10 and 20 PF.
