The EP2 & EP16 scaling proofs ran on 12d1bc32. +The 4‑node efficacy matrix was rebuilt from main tip on 2026‑08‑03 and landed on descendant commits +(0d05a4d2 on the node-a/node-c/node-b containers; 34f17d6 on node-f) — both are direct +descendants of 12d1bc32 on main and add only non‑bnxt changes (e.g. an ionic‑RoCE dmabuf fix), +so EP/IO behaviour on this NIC is unchanged. The build script now pins 12d1bc32 by default to prevent drift.

Findings
+
    +
  • MoRI-EP async_ll passes on every pair — 0 errors, no hang, no crash. The fix generalizes to the whole 235-driver fleet, not just the pair it was first found on.
    • +
  • MoRI-IO is tight: 48.40–48.43 GB/s (~387 Gbps, near 400G line rate), <0.1% variance. No node/pair is an outlier — the fabric + NIC + driver stack is consistent.
    • +
  • Topology-independent at this scale — same-rack (B) and cross-rack (A, C, D) perform identically for both tests.
    • +
+
+

Note: the default v1/InterNodeV1 EP kernel is deliberately not in this matrix — it is known to hang on Thor2 (root cause #2). async_ll is the required kernel for this NIC.

+
Why this matters
+ The fix is topology‑independent. It works identically whether the container owns the host + network (the way MoRI's own tests run) or receives a rail‑matched NIC inside a Kubernetes pod netns via DRANET + (the serving‑style path). Same ~48.4 GB/s IO, same 0‑error EP in both. The k3s test claimed + 1 GPU + 1 Thor2 NIC per pod (gpu.amd.com + dra.net DRA), no host‑network, + no GLM — a clean transport‑level proof. +
+ + +

6The problem & the two blockers

+

+MoRI‑EP internode must (a) create a GPU‑resident completion queue via Broadcom +Direct‑Verbs, then (b) run a GPU‑initiated all‑to‑all dispatch/combine over RDMA. +Two distinct failures sat on this path; MoRI‑IO (pure RDMA WRITE) was never affected by either. +

+ + +

7Root cause #1 — DV‑CQ creation fails on the 237/238 driver

+

On the 237/238 bnxt drivers, MoRI‑EP aborts the moment it creates its GPU‑resident CQ:

+
bnxt_re_dv_create_cq_cmd: execute_ioctl() failed: 5
+bnxt_re_dv_create_cq: bnxt_re_dv_create_cq_cmd() failed
+.../transport/rdma/providers/bnxt/bnxt.cpp:108: Assertion `cq' failed.
+kernel: infiniband rocepNNsN: Create HW CQ failed!
+        bnxt_re_handler_BNXT_RE_METHOD_DV_CREATE_CQ: Failed to create qplib cq
+
+
Root cause (driver source diff, 235 vs 237)
+ Both drivers ship the CQ‑dmabuf path. The regression is that 237 added a new + bnxt_re_setup_cq_hwqs() + cq_timer_reset/cfg step in the DV CQ‑create path + that returns EIO on our Thor2 firmware. The 235.2.86.0 driver has none of it and + uses the older path that works with the existing firmware — so the fix is driver‑only, with no firmware reflash. +
+ + +

8Root cause #2 — RDMA atomics into GPU VRAM (the real wall)

+

+With the 235 driver the CQ creates, EP advances — process group up, I'm pe 0/1 in 2 pes, +Round 0 gen test_data done — then hangs at dispatch. The NIC hardware counters explain why: +

+
rdma3 (benic4) hw_counters at the hang:
+  rx_atomic_requests = 2      # EP dispatch issues RDMA atomics
+  tx_atomic_req      = 4
+  res_rx_pci_err     = 1      # NIC failed a PCIe access as atomic completer
+  unrecoverable_err  = 4
+  tx_write_req       = 402    # plain WRITEs flow fine
+kernel: infiniband rdma3: bnxt_re_handle_qp_async_event: (user) qp_id 0x401 sq cons 0 rq cons 0

NIC — Thor2 (0000:60:00.0)

+ 
AtomicOpsCap: 32bit- 64bit- 128bitCAS-
+

advertises NO atomic‑completer capability

+
+
+ +
+
Mechanism
+ MoRI‑EP's default v1 / InterNodeV1 kernel posts RDMA AMO_ADD atomics into the + peer's GPU‑VRAM counters (token‑count / barrier signalling). The Thor2 NIC must complete those atomics + against local GPU‑VRAM across the PCIe root complex — but it has no atomic‑completer capability, so the + access errors (res_rx_pci_err), the RC QP goes unrecoverable, and dispatch wedges. Plain WRITEs + (what MoRI‑IO uses) are unaffected — which is why MoRI‑IO always worked. +
+

Fix: the async_ll (AsyncLL) kernel signals via RDMA WRITE + poll instead of atomics +(the atomic calls are disabled in its source), so it never touches the NIC's missing atomic path.

+ + +

9The fix

+
+
+

Fix #1 — driver 235.2.86.0

+

Install bnxt 235.2.86.0 (kernel bnxt_en/bnxt_re + userspace libbnxt_re), reboot. Firmware stays 238.1.138.0.

+
    +
  • Public debs: packages.broadcom.com/artifactory/ethernet-nic-debian-public/pool/main/
    • +
  • Clears the bnxt_re_dv_create_cq EIO
    • +
+
+
+

Fix #2 — async_ll kernel

+

Select the WRITE‑based EP kernel (standalone tests take it on the CLI; vLLM via a small selector patch).

+ 
--kernel-type async_ll
+

GLM top-k = 8 < warpSize 64 (AsyncLL requirement satisfied); prefers MORI_ENABLE_SDMA=1.

+
+
+ + +

10Hardware & counter evidence for the fix

+

+Proof the fix is genuine: after many async_ll runs the atomic and PCIe‑error counters stayed +frozen while WRITE traffic climbed into the millions — i.e. async_ll issues +zero atomics and zero new PCIe errors, exactly as designed: +

+
rdma3 (benic4) hw_counters after all async_ll runs:
+  rx_atomic_requests = 2          # FROZEN (leftover from the earlier v1 run)
+  res_rx_pci_err     = 1          # FROZEN — no new PCIe errors
+  tx_write_req       = 4,719,266   # exploded — async_ll is pure WRITE
+  rx_write_requests  =   472,500
+ + + + + + + +

res_rx_pci_err11 (frozen)no new PCIe completer errors
tx_write_req4024,719,266all signalling now via WRITE
+ + +

11Upstream CI cross‑check — why v1 passes there but not here

+

+The MoRI project's own CI runs a dedicated 2‑node Broadcom (BNXT) internode lane. On the +exact commit we tested (12d1bc3), that lane runs every EP kernel — including the +default atomic v1/InterNodeV1 — and they all pass. This is the key data point for the +escalation: it isolates our issue to hardware/firmware, not MoRI software. +

+

+ +
+
The gap — two orthogonal differences
+

1. The v1‑atomic gap = the NIC's PCIe atomic‑completer capability — a + hardware/firmware property of the specific Broadcom board, not the MoRI code or driver version. The CI + runner's Broadcom NIC/fw can complete RDMA atomics into GPU VRAM (AtomicOpsCap 32/64bit+), so + v1's AMO_ADD atomics succeed. Our BCM57608‑P2200DQF01 / fw 238.1.138.0 + advertises AtomicOpsCap 32bit- 64bit- (verified by lspci) — it physically cannot, so v1 + faults (res_rx_pci_err) and hangs. Same MoRI code, same gfx942 — different silicon/fw capability.

+

2. Why the 237 driver failed for us specifically — a separate, earlier + blocker: our 237 driver hit the DV‑CQ‑create EIO (setup_cq_hwqs step) on our + firmware 238.1.138.0. The CI runs a different firmware where that CQ path works — so the CI never sees our EIO. + We worked around this with the 235 driver.

+
+ +
+
Why this explanation holds
+ The CI passes because its Broadcom NIC+fw supports both things our stack lacks: (a) the DV‑CQ‑create + path the 237 driver expects, and (b) RDMA atomic‑completion to GPU BAR. The decisive proof it is not + a MoRI/software gap: our async_ll result is identical to the CI's async_ll pass + — both green. async_ll uses WRITE+poll (never atomics), so it is the portable path that works on + both NIC types. On our hardware it is the required kernel; on atomic‑capable NICs it is simply one valid option. + (CI uses ROCm 7.2.4 vs our 7.2.3 — not the cause: atomic completion is a PCIe/NIC‑level property, below ROCm.) +
+ + +

# 1. Install the 235 driver on each node, then reboot

+# 2. Launch the MoRI container + build MoRI (per node)
+sudo ./scripts/launch_container.sh <IMAGE>
+sudo docker exec mori_host bash -c "$(cat scripts/build_mori.sh)"

  • Broadcom / AMD (NIC — the key ask): the MoRI CI's MI325X_BNXT runner passes the atomic v1 kernel (see §10), so some Broadcom board+fw can complete RDMA atomics to GPU BAR. What board SKU + firmware does that CI runner use, vs our BCM57608‑P2200DQF01 / fw 238.1.138.0 which advertises AtomicOpsCap 32bit- 64bit-? If a firmware exists that flips AtomicOpsCap on our board, v1/v1_ll EP would work here too; otherwise async_ll is the required kernel on our hardware.
    • +
  • Broadcom (driver): fix the ≥237 driver's CQ path (setup_cq_hwqs/cq_timer) so it works on this firmware, removing the need to pin 235.2.86.0.
    • +
  • AMD / MoRI & vLLM: make async_ll the default / auto‑selected EP kernel for NICs without atomic‑completer capability, so GLM wide‑EP serving selects it automatically on Thor2.
    • +
  • Cluster hardware: node node-e is down on a PSU/power‑feed fault (recurring "Power Supply AC lost" in the BMC SEL) — needs a PDU AC‑cycle or physical service; not recoverable from the BMC.
