InfiniBand Training

Key characteristics and aspects of our InfiniBand administration and HPC networking course include:

1. RDMA Architecture and Protocols:

   • Deep dive into Remote Direct Memory Access (RDMA), including InfiniBand verbs, RC (Reliable Connection), UD (Unreliable Datagram), and RoCE (RDMA over Converged Ethernet).

2. Subnet Management & OpenSM:

   • Configuring and managing InfiniBand Subnet Managers (OpenSM), GUID assignments, path resolution, and fabric initialization.

3. Fabric Topology & Switch Configuration:

   • Designing high-availability leaf-spine topologies, managing adaptive routing, congestion control, and Link Layer flow control (Credit-based flow control).

4. Performance Tuning & Diagnostics:

   • Using diagnostic utilities like ibdiagnet, ibstat, perfquery, and ibnetdiscover to monitor link errors, symbol errors, and bandwidth utilization.

5. MPI & AI Cluster Interconnects:

   • Configuring multi-node clustering for Message Passing Interface (MPI) jobs and NVIDIA GPU-accelerated AI training workflows over InfiniBand networks.

6. Storage Fabrics (NVMe-oF):

   • Implementing high-speed storage connectivity using NVMe over Fabrics (NVMe-oF) across InfiniBand infrastructures.

InfiniBand mastery is vital for enterprise data center engineers and HPC administrators managing modern AI superclusters and heavy computational workloads.
