The Salomon supercomputer is currently our largest computing system with an output of 2 PFlop/s. At the time of commissioning in the summer of 2015, it was the 40th most powerful supercomputer in the world according to the TOP500 ranking

Salomon is a petaflop class system consisting of 1,008 computational nodes. Each node is equipped with 24 cores (two twelve-core Intel Haswell processors). These computing nodes are interconnected by InfiniBand FDR and Ethernet networks.

 

There are two types of compute nodes:

  • 576 compute nodes without any accelerator,
  • 432 compute nodes with MIC accelerators (two Intel Xeon Phi 7120P per node).

Each node is equipped with two 2.5 GHz processors and 128 GB RAM. The total theoretical peak performance of the cluster exceeds 2 PFlop/s with an aggregated LINPACK performance of over 1.5 PFlop/s. All computing nodes share a 500 TB/home disk storage to store user files. A 1,638 TB shared storage is available for scratch and project data.
