System Information

Compute Nodes

The ARIS infrastructure consists of a total of four computing system nodes, based on Intel x86 architecture, interconnected into a single Infiniband FDR14 network offering multiple options and processing architectures. More specifically, the infrastructure consists of:

  • Thin Nodes island based on the IBM NeXtScale platform and on Intel Xeon E5-2680v2 processors. It has 426 computing nodes and offers a total of 8,520 CPU cores.

  • Fat Nodes island consisting of 44 Dell PowerEdge R820 servers. Each server offers 4 Intel Xeon E5-4650v2 processors and 512 GB of central memory.

  • GPU accelerator nodes comprised of 44 Dell PowerEdge R730 servers. Each server contains 2 Intel Xeon E5-2660v3 processors, 64 GB of memory and 2 NVidia K40 GPU cards, and

  • Xeon Phi accelerator nodes consisting of 18 Dell PowerEdge R730 servers, each containing 2 Intel Xeon E5-2660v3 processors, 64 GB of memory and 2 Intel Xeon Phi 7120P co-processors.

  • Machine Learning node consisting of 1 server, containing 2 Intel E5-2698v4 processors, 512 GB of central memory and 8 NVIDIA V100 GPU card
