16x Spark Cluster (Build Update)

Build is done. 16 DGX Sparks on the fabric, all hitting line rate. Setup was time consuming but honestly smoother than I expected. Each Spark runs Nvidia’s flavor of Ubuntu out of the box with mostly everything pre installed and ready to go. For setup I had to rack them, power on, create the same user/pass across all nodes, wait about 20 minutes per node for updates, then configure passwordless SSH, jumbo frames, IPs, etc. which I scripted to save time. Each Spark connects to the FS N8510 switch with a single QSFP56 cable.
