The dsv4_910c_vllm_tp_dp_matrix experiment was a placeholder (wrong
MODEL_PATH, glm52 image default, no DSV4 serve flags, no driver mounts).
Bring it to a working state, validated end-to-end on 910c.1.
config.env:
- MODEL_PATH: /mnt/models/DeepSeek-V4-Flash -> .../DeepSeek-V4-Flash-w8a8-mtp
(weights downloaded from ModelScope Eco-Tech/DeepSeek-V4-Flash-w8a8-mtp,
~280 GiB, 70 shards, verified present and chowned to shishi)
- SERVED_MODEL_NAME: deepseek-v4-flash -> dsv4 (matches vllm-ascend tutorial)
- DOCKER_IMAGE: vllm-ascend:v0.23.0rc1-a3-openeuler ->
quay.io/ascend/vllm-ascend:v0.23.0rc1-a3-openeuler (full tag, present locally;
the glm5.2-a3 image carries GLM-specific patches and is NOT DSV4-compatible)
- Add DSV4_* serve-flag vars: tokenizer-mode/tool-call-parser/reasoning-parser
deepseek_v4, quantization ascend, expert-parallel, async-scheduling,
MTP speculative-config, compilation-config, additional-config, multithread
model-loader (128 threads for the 280GiB load)
- Rewrite the OOM-boundary comment to reflect actual w8a8 weight size
start_vllm_docker.sh (the main pitfalls vs the glm52 launcher):
- Inject the DSV4_* serve flags (GLM-5.2 needs none of them); without them
vllm rejects the model / lacks MTP
- Mount host driver libs (driver/lib64, dcmi, hccn_tool, npu-smi,
version.info, ascend_install.info, hccn.conf) -- otherwise the container
torch_npu fails with libascend_hal.so not found
- Mount all 16 dies via --device /dev/davinci0..15 + davinci_manager/
devmm_svm/hisi_hdc instead of relying on Ascend Docker Runtime injection
(ASCEND_VISIBLE_DEVICES-only), which was unreliable on this host
- --privileged --shm-size 512g for the 280GiB weight load
- LD_PRELOAD the openEuler jemalloc path /usr/lib64/libjemalloc.so.2
(the glm52 ubuntu path /usr/lib/aarch64-linux-gnu/... does not exist here)
- Raise health-wait budget 240x5s -> 360x10s (DSV4 load+compile ~8min)
- DRY_RUN mode for command preview without launching
Verified: start_vllm_docker.sh 4 2 brings the server up on port 30052 in
~8 min (130s weight load per die, 29s compile, 187s engine init); chat
completion returns correctly, system_fingerprint vllm-0.23.0-tp4-dp2-ep.
