Since the beginning of May 2018, a new supercomputer named Kraken has been setup to reinforce Cerfacs’ simulation capabilities. With a peak performance of 315 Tflop / s this new computer provided by Lenovo is now available to all of Cerfacs’ researchers in addition to the Nemo computer.
The Kraken cluster includes 119 compute nodes, each of them with two Intel Xeon Gold 6140 processors (18 cores skylake processor at 2.3 Ghz) and 96 GB DDR4 memory. This “compute partition” is completed by 3 post-processing nodes with 384 GB memory with a Nvidia Tesla M60 and one node with 768 GB memory used for large mesh generation. The interconnection network is a non-blocking Intel Omnipath Network.
