The 4 Kimi-K3 AgentX configs ran only as gen_only_no_context, because their DWDP16 ctx side could not start: Kimi K3 MoE raised NotImplementedError for DWDP at model init. Since NVIDIA#19960 Kimi K3 supports DWDP on the CUTEDSL MoE backend, which these configs use, so the ctx_only lanes can run. Add them back as they were held back in NVIDIA#20163: - l0_gb300_multi_nodes_perf_sanity_node4_gpu16: the 4 ctx_only ids, each the DWDP16 ctx side as one 16-GPU attention-DP server on 4 nodes. - GB300-16_GPUs-4_Nodes-PyTorch-PerfSanity-Node4-GPU16-Post-Merge, 4 splits, one test per split. The comments in the two gen_only_no_context lists now point at the new list instead of saying the ctx side cannot start. Signed-off-by: chenfeiz0326 <203214996+chenfeiz0326@users.noreply.github.com>
…ep-alive trtllm-serve closes a connection after it has been idle for 5 s (TIMEOUT_KEEP_ALIVE). aiperf keeps idle pooled connections for 300 s, so it sometimes sends a request into a connection the server is closing at that moment. The request fails with ClientOSError(104, "Connection reset by peer"), and the AgentX health check fails the lane on any non-empty- content error. On the Kimi-K3 ctx_only lane this hit 2 of 3 GB300 runs (1 request of ~4400 each), with no error on the server side. Set AIPERF_HTTP_KEEPALIVE_TIMEOUT to 4 s for the aiperf run (setdefault, so an explicit value still wins), so idle connections are dropped on the client first. A unit test keeps the value below the server's constant. Signed-off-by: chenfeiz0326 <203214996+chenfeiz0326@users.noreply.github.com>

Description
#20163 added the 4 Kimi-K3 AgentX configs to post-merge perf-sanity, but only as
gen_only_no_contextlanes. Their ctx side is DWDP16, and Kimi K3 MoE could not run DWDP:KimiK3MoERuntime._routed_moe_model_configraisedNotImplementedError: Kimi K3 packed-checkpoint streaming does not support DWDPat model init, so #20163 held back thectx_onlyande2elanes (33272b2).#19960 (merged 2026-10-17) replaced that raise: Kimi K3 now runs DWDP on the

e2elanes stay held back: they need 8–16 GB300 nodes per run and I have not run them. That's a separate PR.Two problems the GPU runs found, and their fixes
trtllm-llmapi-launch's stop request to the rank-0 MPI Comm Server is lost when the 16-rank DWDP worker teardown outlasts the stop client. Details in [None][fix] Do not lose the MPI Comm Server shutdown request while workers tear down #20608, now merged (16d26df), so this PR's stages no longer hang.Connection reset by peerper run fails the lane (fixed here). 2 of 3 runs had exactly one request of ~4400 fail withClientOSError(104), and the AgentX health check fails the lane on any error that isn't empty-content. trtllm-serve closes a connection after 5 s idle (TIMEOUT_KEEP_ALIVE); aiperf reuses idle pooled connections for up to 300 s, so it sometimes writes into a connection the server is closing at that moment. A local uvicorn + aiohttp reproducer with the same timeouts: 2 resets per 1600 requests at client keep-alive 300 s, 0 at 4 s.agentx_client.pynow setsAIPERF_HTTP_KEEPALIVE_TIMEOUT=4(setdefault, so an explicit value still wins), and a unit test keeps it below the server constant.Test Coverage

ctx_onlycon88 and con220): GenPostMergeBuilds/3040 wheel and its source tree (54eff28, includes #19960), the image pinned at that commit, launch script fromjenkins/scripts/perf/local/submit.py.The ctx side loads and serves on all 16 ranks:
Dwdp Manager initializedand DWDP setup complete on 16/16; 149.6 GiB weights per rank before DWDP setup, peak 232 GiB during memory profiling, 51.1 GiB KV quota; no OOM. The server is ready ~25 min after start (16k-token autotune ~9 min). AgentX: 93/93 warmup trajectory primers, 0 errors, then the 1800 s measured window.ClientOSError(104)ClientOSError(104)All five runs use one wheel and differ only in the config and change columns.
TTFT is dominated by long prompts (ISL p50 ~90k, max ~760k–950k tokens).
con220 runs the same ctx worker as con88 (max batch 16, 16k tokens), so its 220 concurrent sessions queue for prefill. Effective prefill concurrency averages 167, against 49 for con88. Its TTFT tail is therefore queueing time, not prefill latency: p99 17.5 min. The AgentX warmup sends 244 trajectory primers instead of 93 and takes 26 min. The lane is still stable, with 0 errors and an 84-min pytest against its 110-min timeout. con138 and con63 first ran in CI (table below). Of what
ctx_onlyruns, only their client concurrency differs from con88 (138 and 63, both between the two tested loads). They also change a spec-decode acceptance env, which has no effect on the ctx worker because it runs without speculative decoding.CI (this PR's run on
