Subject: [PATCH 1/2] minimaxm3-fp8-b200-vllm-mtp: day-zero MiniMax-M3 EAGLE3
 B200 recipe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the spec-decoding=mtp sibling of minimaxm3-fp8-b200-vllm: same
MXFP8 target and serve shape, plus the Inferact/MiniMax-M3-EAGLE3 draft
head via --speculative-config (method eagle3, 3 speculative tokens).
The drafter is pinned to FLASH_ATTN — the EAGLE3 head is MHA and
FlashInfer only supports the mandatory page size 128 through its
GQA-only trtllm-gen kernel (the failure that hit the B300 MTP canary).
Cudagraph capture scales to CONC * (1 + spec tokens); benchmark prompts
run through the chat template so acceptance reflects real text. The
EAGLE3 draft is fetched next to the pre-staged target on b200-dgxc
(gharunners tree is writable) or into the HF cache on bare-HF-id
runners. Search space mirrors the non-MTP entry trimmed at the
extreme-concurrency end, identical to the minimaxm3-fp8-b300-vllm-mtp
precedent. Launcher needs no change — launch_b200-dgxc.sh already
carries SPEC_SUFFIX and resolves the _mtp script.

+# MiniMax-M3 MXFP8 B200 single-node vLLM recipe with EAGLE3 speculative
+# decoding — the repo's spec-decoding=mtp variant of minimaxm3_fp8_b200.sh
+# (https://recipes.vllm.ai/MiniMaxAI/MiniMax-M3). Adds the
+# Inferact/MiniMax-M3-EAGLE3 draft head via --speculative-config with 3
+# speculative tokens. Everything else keeps the non-MTP serve shape:
+# --block-size 128 is mandatory (MSA sparse_block_size is 128; the default 16
+# misaligns sparse indexing), and --language-model-only skips the vision
+# encoder for the text-only benchmark. dp-attn=true maps to DP×EP (DEP);
+# ep>1 maps to TP+EP (TEP).
+#
+# The drafter is pinned to FLASH_ATTN: the EAGLE3 head is MHA, and FlashInfer
+# only supports page size 128 through its trtllm-gen kernel, which requires
+# GQA/MQA — engine init dies in FlashInferMetadataBuilder otherwise (the
+# failure hit on the B300 MTP canary). The target keeps its default
+# (FlashInfer) backend; FLASH_ATTN takes any multiple-of-16 block size, so
+# the mandatory 128 is fine for the draft.
