Hardware Configuration

  • 144 standard compute nodes

    • 2× AMD EPYC 7742, 2× 64 cores, 2.25 GHz

    • 256 (16× 16) GB DDR4, 3200 MHz

    • InfiniBand HDR100 (Connect-X6)

    • local disk for operating system (1× 240 GB SSD)

    • 1 TB NVMe

  • 61 accelerated compute nodes

    • 2× AMD EPYC 7742, 2× 64 cores, 2.25 GHz

    • 256 (16× 16) GB DDR4, 3200 MHz

    • InfiniBand HDR100 (Connect-X6)

    • local disk for operating system (1× 240 GB SSD)

    • 1 TB NVMe

    • 1× NVIDIA V100 GPU with 16 GB HBM2e

  • 4 login nodes

    • 2× AMD EPYC 7742, 2× 64 cores, 2.25 GHz

    • 256 (16× 16) GB DDR4, 3200 MHz

    • HDR 100-Infiniband (Connect-X6)

    • 100 Gigabit Ethernet external connection

    • local disk for operating system (2× 480 GB SSD in RAID 1)

  • 26,240 CPU cores

  • 944.6 (CPU) + 427 (GPU) Teraflop per second peak performance

  • Mellanox InfiniBand HDR full fat-tree network with HDR100 speed on the nodes and full HDR on the inter-switch level

  • 100 Gbit/s network connection per login node and 40 Gbit/s network connection per compute node to JUST for storage access

The compute nodes can be moved flexibly between the cluster and the cloud module.

Note

Cloud nodes do NOT have Infiniband. GPU nodes available for the cloud can host 4 vGPUs, allocated to one physical NVIDIA V100.

Software Overview

The software is based on RedHat OpenStack Platform. For further information see the OpenStack documentation.
