# MiMo-V2.6-Flash-MOPD on 2 nodes — SparkRing runtime stack, their qualified
# profile `profiles/mimo-v26-flash-mopd-tp2` (topology direct-pair-2),
# transcribed to sm121 form. INTENDED CLUSTER: `2nodes-dac` (dgx1+dgx2,
# 192.168.100.x DAC pair — the nccl block routes over the f1 ports; verified
# 2026-09-29 that the f1 GID table carries IPv4 RoCE-v2 at index 3).
#
# Deviations from their tp2 profile (same policies as our tp4 lane,
# see specs/tech-architecture/sparkring-mimo-lanes.md):
#   * port 30000 (cluster default), launcher-generated rank/master flags;
#   * model from the mounted HF cache (same pinned snapshot 2479e2d0029e —
#     config/index sha verified against their profile);
#   * their 12 GiB `--kv-cache-memory-bytes` pin NOT adopted (auto pool;
#     at TP2 weights ≈ 87 GiB/rank leave ≈10-15 GiB auto ≈ 500-750K tokens,
#     plenty for 256K×c2 — operator policy: no pins);
#   * max-model-len 524288 (prod parity; the MML A/B on the c2 axis was
#     bit-identical — diagnosis of "c2 collapse" is in the lanes doc);
#   * NO Switchless/Ring machinery: HCA/GID/socket come from the cluster
#     nccl block (f1 pair); the ONE tp2-only transport key their profile
#     carries for the direct pair, `B12X_ROCE_PAIR_PATHS=2`, is kept.
