# MI355X DeepSeek-V4-Flash FP8 4-node 2P1D disaggregation recipe — narrow-prefill EP8 + MTP
|
||||
# + wide-decode EP16 (Oren's config: wide EP only helps decode).
|
||||
#
|
||||
# Two prefill engines (EP8, one node each; the router fans requests across both) +
|
||||
# one decode engine (EP16) spanning 2 nodes. Still one logical P/D pair per role
|
||||
# group, 4 nodes total. nodes-per-engine = ceil(TP/8): prefill 8->1, decode 16->2,
|
||||
# so the launcher emits cross-node --nnodes/--node-rank/--dist-init-addr for the
|
||||
# decode engine only. Prefill EP8 keeps MoE all-to-all INTRA-node (XGMI, known
|
||||
# good); decode gets wide EP16 across nodes. Mismatched-TP KV (prefill TP8 ->
|
||||
# decode TP16) is layout-compatible for DeepSeek MLA (KV is a replicated per-token
|
||||
# latent, not head-sharded), and is carried over mori.
|
||||

||||
# Consumed by:

# * scripts/ci/slurm/process_result.py reads `resources` and
|

# `backend.sglang_config` (TP/EP/DP + worker counts) for the summary table.
