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.
