Anselm was installed in the summer 2013 with a theoretical peak performance of 94 TFlop/s. Anselm consists of 209 computational nodes. Each node is equipped with 16 cores (two eight-core Intel Sandy Bridge processors). These computing nodes are interconnected by InfiniBand (QDR) and Ethernet networks.
There are 4 types of compute node:
- 180 compute nodes without any accelerator, with 2.4 GHz CPUs and 64 GB RAM,
- 23 compute nodes with GPU accelerators (NVIDIA Tesla K20), with 2.3 GHz CPUs and 96 GB RAM,
- 4 compute nodes with MIC accelerators (Intel Xeon Phi 5110P), with 2.3 GHz CPUs and 96 GB RAM,
- 2 fat nodes with larger RAM and faster storage (2.4 GHz CPUs, 512 GB RAM and two SSD drives).
The total theoretical peak performance of the whole cluster is 94 TFlop/s with a maximal LINPACK performance of 73 TFlop/s.
