Network

All of the compute and login nodes of BarboraNG are interconnected through an InfiniBand NDR200 Gbps network and a Gigabit Ethernet network.

Compute nodes and the service infrastructure is connected by the NDR 200/400/800G technology.

The computing network thus implemented fulfills the following parameters

• 200Gbps throughput
• Latencies less than 10 microseconds
• Adaptive routing support
• MPI communication support
• IP protocol support (IPoIB)
