docker pull ghcr.io/fujitsupolycom/sparkring@sha256:2375f876bc9ea065e85ae10cebad7a8db8a2ec0e6862b4441c269c5bf56365c6

Version tag: ghcr.io/fujitsupolycom/sparkring:shared-2026.09.3.

Changes

• Release GLM kernel-preparation inputs after preparation to recover serving memory.
• Support verified native-image GLM launchers, B12X loading and separate Spark/QAD checkpoint choices.
• Retain B12X #394 and the applicable prefill, communication and SparkCache integrations.

Qualified selections

Bounded text, finite-score, synthetic-media and retained-restart checks passed for:

Model / checkpoint	Parallelism	SparkCache	Quickstart
Qwen3.8-Flash-Next QAD	TP2/DCP1	Off	TP2 guide
Qwen3.8-Flash-Next QAD	TP2/DCP1	On	TP2 + SparkCache
Qwen3.8-Flash-Next QAD	TP4/DCP1	Off	TP4 guide
Qwen3.8-Flash-Next QAD	TP4/DCP1	On	TP4 + SparkCache
GLM-5.3-Flash NVFP4 QAD	TP2/DCP1	On	TP2 guide — select nvfp4-qad
GLM-5.3-Flash NVFP4 QAD	TP4/DCP1	On	TP4 guide — select nvfp4-qad
GLM-5.3-Flash NVFP4-Spark	TP2/DCP1	On	TP2 guide — select nvfp4-spark
GLM-5.3-Flash NVFP4-Spark	TP4/DCP1	On	TP4 guide — select nvfp4-spark

NVFP4-Spark is not QAD. Qwen's shared guides document both cache modes; select
the mode listed in the table.

Cache-enabled checks restored both fixtures on every physical rank. Full-context,
C16 pressure, arbitrary media accuracy and long-duration stability are not
qualified. No performance results are published. An earlier-image GLM TP4
collective timeout did not recur; its root cause remains unresolved.

Use the profile quickstarts
and exact release record.
GLM cache-disabled/DCP4 and DeepSeek profiles retain independent image pins.

Attached source archives and manifest identify the vLLM/B12X payload. Other
component terms and inherited-source limitations are in
the component inventory.
Model weights are separate. Preserve the preceding image, settings and cache
roots for rollback.
