Subject: [PATCH 1/4] feat(minimaxm3-mi325x-agentic-mtp): add EAGLE3 AgentX
 recipe with golden-AL synthetic acceptance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add minimaxm3-fp8-mi325x-vllm-agentic-mtp, the spec-decoding=mtp variant of the
MiniMax-M3 MXFP8 MI325X agentic-coding recipe: Inferact/MiniMax-M3-EAGLE3 draft
head, 3 speculative tokens, no drafter backend pin (server-wide TRITON_ATTN),
and synthetic acceptance pinned to the committed golden AL 2.83
(minimaxm3_eagle3.yaml, thinking_on, K=3). EVAL_ONLY keeps real verification.
The pinned ROCm nightly postdates vllm-project/vllm#45546, so no in-place
SupportsEagle3 patch is needed.

中文：新增 minimaxm3-fp8-mi325x-vllm-agentic-mtp，即 MiniMax-M3 MXFP8 MI325X 智能体
编码配方的投机解码（spec-decoding=mtp）变体：Inferact/MiniMax-M3-EAGLE3 草稿头、
3 个投机 token；服务端整体使用 TRITON_ATTN，drafter 无需固定注意力后端；合成接受
长度固定为黄金 AL 2.83（minimaxm3_eagle3.yaml，thinking_on，K=3）。EVAL_ONLY 保留
真实验证。所选 ROCm nightly 镜像晚于 vllm-project/vllm#45546，无需运行时补丁。

+# MiniMax-M3 MXFP8 MI325X (gfx942) AgentX (agentic-coding) recipe with EAGLE3
+# speculative decoding — the spec-decoding=mtp variant of
+# agentic/minimaxm3_fp8_mi325x.sh. Everything outside the speculative block
+# mirrors the non-MTP agentic sibling (Mooncake host-DRAM KV offload over TCP,
+# --block-size 128, --language-model-only, TRITON_ATTN, FP8 KV on the nightly
+# images, minimax_m3 parsers, VLLM_USE_BREAKABLE_CUDAGRAPH=0, TP4 gmu bump), so
+# the spec-decode delta is readable at equal concurrency.
+#
+# Speculative config: Inferact/MiniMax-M3-EAGLE3 draft head, 3 speculative
+# tokens. Unlike the CUDA recipes the drafter needs no attention_backend
+# override — the FlashInfer "page size 128 requires GQA/MQA" limitation that
+# forces FLASH_ATTN for the MHA EAGLE3 head is FlashInfer/CUDA-specific, and
+# here the whole server runs TRITON_ATTN, which serves the MHA draft fine
+# (same reasoning as fixed_seq_len/minimaxm3_fp8_mi325x_mtp.sh).
+#
+# No in-place SupportsEagle3 patch: the pinned ROCm nightly is built from
+# upstream 2026-06-23, after vllm-project/vllm#45546 (EAGLE3 support on the AMD
+# MiniMax-M3 model) merged on 2026-06-14. The fixed-seq-len MI325X MTP recipe
+# still carries that runtime patch because it runs the older
+# vllm-openai-rocm:minimax-m3 bring-up image.
+#
+# Throughput runs pin synthetic acceptance to the committed golden AL; the
+# EVAL_ONLY accuracy run keeps real target verification. See SYNTHETIC_ACCEPT_LEN.

Subject: [PATCH 3/4] fix(minimaxm3-mi325x-agentic-mtp): gmu 0.90 for the
 EAGLE3 draft; conc grid steps >=2, stops at 16
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two corrections:
- gpu-memory-utilization 0.90 (was 0.95, and 0.98 at TP4). The H100 twin died
  mid-warmup with torch.OutOfMemoryError on all 8 ranks (run 30515793863) at the
  non-MTP sibling's value; fixed_seq_len/minimaxm3_fp8_mi325x_mtp.sh passes no
  gmu flag at all, i.e. vLLM's 0.90 default.
- Concurrency grid: GPU-resident [1,4,8,12,16], Mooncake [4,8,12,16], DEP
  [8,12,16]. Every step is >=2 and every arm stops hard at 16; 74 jobs -> 34.

中文：两处修正：(1) gpu-memory-utilization 改为 0.90（原为 0.95，TP4 为 0.98）——
本配方的 H100 版本在非 MTP 取值下于预热阶段 8 个 rank 全部 OOM（run 30515793863），
而 fixed_seq_len/minimaxm3_fp8_mi325x_mtp.sh 未设置该参数（即 vLLM 默认 0.90）。
(2) 并发网格：GPU 常驻 [1,4,8,12,16]、Mooncake [4,8,12,16]、DEP [8,12,16]；相邻
并发间隔至少为 2，且一律止于 16，作业数由 74 降至 34。

Mooncake is not used on AMD. The HIP-built transfer engine runs over TCP on
these clusters and the store collapses mid-replay ("ServerSession::readBody
failed ... Connection reset by peer" until AIPerf aborts), as the MI300X sibling
hit in run 30517360090.

Remove all three host-DRAM arms and the in-script Mooncake build/launch
plumbing. The recipe is GPU-resident only (TP4, TP4/EP4, TP8, TP8/EP8, TP8/DEP8;
34 jobs -> 23) and hard-fails if a dram row is ever pointed at it.

中文：AMD 上不再使用 Mooncake —— 基于 HIP 构建的传输引擎在这些集群上走 TCP，运行中
store 会崩溃（持续输出 "ServerSession::readBody failed ... Connection reset by peer"
直至 AIPerf 中止），MI300X 版本已在 run 30517360090 中复现。删除全部三条主机 DRAM
分支及脚本内的 Mooncake 构建/启动逻辑，改为仅 GPU 常驻（TP4、TP4/EP4、TP8、TP8/EP8、
TP8/DEP8，作业数由 34 降至 23）；若仍传入 dram 配置将直接报错退出。
