The CalcUA infrastructure currently consists of the clusters Hopper and Leibniz, providing a total of 320 compute nodes which deliver more than 240 teraflop of computing power.
Leibniz was installed in the spring of 2017. It is a NEC system consisting of 152 nodes with dual 14-core Intel E5-2680v4 Broadwell generation CPUs connected through an EDR InfiniBand network. This cluster also contains a node for visualisation, 2 nodes for GPU computing (NVIDIA Pascal generation), one node with dual NEC SX-Aurora TSUBASA vector processors and one node with an Intel Xeon Phi expansion board.
