Hardware Overview
The Anselm cluster consists of 209 computational nodes named cn[1-209] of which 180 are regular compute nodes, 23 are GPU Kepler K20 accelerated nodes, 4 are MIC Xeon Phi 5110P accelerated nodes, and 2 are fat nodes. Each node is a powerful x86-64 computer, equipped with 16 cores (two eight-core Intel Sandy Bridge processors), at least 64 GB of RAM, and a local hard drive. User access to the Anselm cluster is provided by two login nodes login[1,2]. The nodes are interlinked through high speed InfiniBand and Ethernet networks. All nodes share a 320 TB /home disk for storage of user files. The 146 TB shared /scratch storage is available for scratch data.
The Fat nodes are equipped with a large amount (512 GB) of memory. Virtualization infrastructure provides resources to run long-term servers and services in virtual mode. Fat nodes and virtual servers may access 45 TB of dedicated block storage. Accelerated nodes, fat nodes, and virtualization infrastructure are available upon request from a PI.

The cluster compute nodes cn[1-207] are organized within 13 chassis.
There are four types of compute nodes:
- 180 compute nodes without an accelerator
- 23 compute nodes with a GPU accelerator - an NVIDIA Tesla Kepler K20m
- 4 compute nodes with a MIC accelerator - an Intel Xeon Phi 5110P
- 2 fat nodes - equipped with 512 GB of RAM and two 100 GB SSD drives
GPU and accelerated nodes are available upon request, see the Resources Allocation Policy.
