deploy: b300 build scripts with pip cache mount + no-build-isolation fast path

Base image already has torch 2.13, but pyproject build-system.requires pulls it into pip's isolated build env on every build (~6GB via throttled mirror, 47min). --no-build-isolation reuses the base env; build.sh picks Dockerfile.fast (--no-deps) when python/pyproject.toml is unchanged.

+# 优化版（2026-09-24）：解决清华源限流下每次构建重下 torch 的问题。
+# 要点：
+#  1. pyproject build-system.requires 含 torch==2.13.0，pip 隔离构建环境每次都重下 ~6GB。
+#     基底镜像已装 torch 2.13 → 用 --no-build-isolation 复用，构建环境零下载。
+#  2. 基底缺 setuptools-scm（版本打戳要用），单层预装 + pip cache mount，只下载一次。
+#  3. RUN 的 pip cache mount 持久化在宿主机，依赖解析命中的包不再重复下载。

minke.yu	4f0ca95477	deploy: b300 build scripts with pip cache mount + no-build-isolation fast path Base image already has torch 2.13, but pyproject build-system.requires pulls it into pip's isolated build env on every build (~6GB via throttled mirror, 47min). --no-build-isolation reuses the base env; build.sh picks Dockerfile.fast (--no-deps) when python/pyproject.toml is unchanged.	2026-09-24 13:11:41 +08:00
minke.yu	b91137ab98	scheduler: CP-symmetric idle check for health-check admission build-sglang-image / build (push) Successful in 27m52s Details Health-check admit/skip used is_fully_idle(), which includes rank-local hicache drain queues; ranks diverge right after activity, so one rank dispatched the health-check generate while others piggyback-skipped, deadlocking CP (hicache drain all_reduce vs CP request broadcast). Seen on cp2/cp4 + hicache L3 after router health checks. Recovered from b300 /data/ymk/sglang working copy (uncommitted WIP).	2026-09-24 12:01:57 +08:00

Xinyuan Tong	6833498646	model: prune comments and redundant tests in dsv41 vision CP	2026-09-23 14:36:01 +08:00
Xinyuan Tong	b48e2cb1eb	model: TP-wide single-owner image encoding for DeepSeek V4.1 ViT and Aligner are replicated per TP rank, encoding each image eight times with TP8 on both CP1 and CP8. Elect one owner per image and use ordered full-span broadcasts with a six-phase agreement protocol. Both CP1 and CP8 benefit while local cache hits preserve collective order.	2026-09-23 14:36:01 +08:00
Xinyuan Tong	bfeb7cd9b2	model: support DeepSeek V4.1 vision with interleave prefill CP The CP runner bypassed the vision merge and used bare text embeddings. Merge image features before sharding so request-global offsets stay valid. Canonicalize model IDs separately to preserve scheduler hash IDs. Keep unsupported combinations guarded and isolate embedding overrides from multimodal prefills without starving queued FCFS requests.	2026-09-23 14:36:00 +08:00
