GPU economics, inference, multi-node training and bare-metal infrastructure — notes from the team running whole-node B300.
Whole-node vs fractional GPU rental — how to choose
Fractional GPUs, MIG, vGPU and shared hosts look cheaper by the hour. Here is when they cost you more, and when a whole bare-metal node is the right unit.
Multi-node training — what the fabric actually does
When training outgrows one node, the network sets your scaling efficiency. A practical look at NVLink, InfiniBand, collective operations and non-blocking topology.
