Discover, diagram, and diagnose the RDMA/GPU network topology of a GPU cluster (rails, NICs, GID/RoCE config, GPU<->NIC PCIe affinity), determine whether the fabric supports cross-rail communication, and localize a failure to a fabric tier (NIC / leaf /…

Known environment issues that make MORI slow or behave oddly without being MORI bugs — currently: HIP VMM peer traffic silently falling off XGMI onto PCIe/host memory on Linux kernels built without CONFIG_DMABUF_MOVE_NOTIFY / CONFIG_PCI_P2PDMA, which hits…

Deploy and set up the MORI environment in a fresh Docker container or bare host: start the container, install ROCm dependencies, NIC userspace libraries (AINIC/Broadcom/Mellanox-NVIDIA), RDMA-core, and MORI itself. Use when the user asks to deploy MORI,…

Add a new storage medium to UMBP's distributed mode as a MediumBackend (HBM, SSD, CXL, a remote object store, a fake for tests). Covers the two shapes a backend can take — a PageMemorySource for anything page-addressable, or a full MediumBackend for a medium…

Add a new byte-moving path to UMBP's distributed mode as a TransferEngine (GPU copy, a second RDMA transport, a file/GDS engine, a fake for tests). Covers CanHandle pair-dispatch and why engines must be disjoint, the Plan/Submit/Wait split, bounce buffers,…

Write GPU kernels that move data with the CCO SDMA device API (ccoSdma: put/get/quiet/waitSignal/commit). Covers the build flags and env vars needed to turn the path on, which template arguments and coop scope to pick, how completion and signals work, and the…
