MORI tests measure RDMA put, write, and I/O throughput over the InfiniBand fabric using AMD Pensando AINIC and other RDMA-capable devices. Run MORI to validate raw RDMA performance before training or inference workloads.

Set up config#

  1. Copy the MORI RDMA configuration file:

    cvs config copy mori/mi35x_mori_config.json --output ~/cvs_workspace/mori/mi35x_mori_config.json

  2. Edit the file and configure:

    • no_of_nodes — number of nodes in the cluster

    • Every field still set to <changeme> — replace with cluster-specific values before running

For the complete field reference, see MORI network configuration file reference for Cluster Validation Suite (CVS).

Run tests#

You can list all available MORI test cases using the CLI:
