Connect Three DGX Spark in a Ring Topology

Connect and set up three DGX Spark devices in a ring topology

Configure three DGX Spark systems in a ring topology for high-speed inter-node communication using 200GbE direct QSFP connections. This setup enables distributed workloads across three DGX Spark nodes by establishing network connectivity and configuring SSH authentication.

Outcome: You will physically connect three DGX Spark devices with QSFP cables, configure network interfaces for cluster communication, and establish passwordless SSH between nodes to create a functional distributed computing environment.
