将 GLM-5.2 B200 AgentX 聚合式与分离式配置改由 Nscale 集群运行:注册新的 cluster:b200-nscale 精确机群标签,扩展 launch_b200-nscale-slurm.sh 支持该模型/框架组合并对本地 NVMe 模型路径跳过 srtctl preflight,同时撤销此前对 launch_b200-dgxc.sh 的改动。

sbatch_directives.cpus-per-task was ported verbatim from NVIDIA/srt-slurm#314 (a DGXC-tuned value) and does not match the b200-nscale cluster's registered per-node CPU count, causing every job routed there to fail at submission with 'sbatch: error: CPU count per node can not be satisfied'. All three recipes already request the whole node via use_exclusive_sbatch_directive: true, so the explicit cpus-per-task constraint is redundant on top of --exclusive and safe to drop entirely (precedent: sglang/glm5.2/agentic/disagg-h200-2p2d-*.yaml already omits it).

Duplicate nscale cluster runner mapping
Low Severity
cluster:b200-nscale is inserted again even though the same key and runner list already exist earlier in runners.yaml. Duplicate YAML keys are last-write-wins, so a later edit to only one block can be silently ignored.

Description
Adds Dynamo-SGLang AgentX coverage for GLM-5.2-NVFP4 on B200: one aggregated
TP8 config and one disaggregated config carrying two topologies (1P2D, 1P3D).
glm5.2-fp4-b200-dynamo-sglang-agentic-agg: single TP8 worker doing bothprefill and decode, swept at concurrency 2, 4, 8, and 12.
glm5.2-fp4-b200-dynamo-sglang-agentic-disagg: EP8/DP-attention prefillagainst either 2 or 3 TP8 decode workers (1P2D / 1P3D), both at concurrency
113, using NIXL for KV transfer between prefill and decode.

golden_al_distribution/glm5.2_mtp.yaml(2.99 for the aggregate 3-step config, 2.5 for the disaggregated 2-step
decode config) for throughput runs only —

中文说明
为 B200 上的 GLM-5.2-NVFP4 新增 Dynamo-SGLang AgentX 覆盖:一个聚合式 TP8 配置,
以及一个包含两种拓扑(1P2D、1P3D)的分离式配置。
glm5.2-fp4-b200-dynamo-sglang-agentic-agg:单个 TP8 worker 同时承担 prefill和 decode,在并发度 2、4、8、12 下扫描。
glm5.2-fp4-b200-dynamo-sglang-agentic-disagg:EP8/DP-attention 的 prefill分别对接 2 个或 3 个 TP8 decode worker(1P2D / 1P3D),均在并发度 113 下运行,
prefill 与 decode 之间使用 NIXL 传输 KV。
acceptance 固定为
golden_al_distribution/glm5.2_mtp.yaml中的 golden 值(聚合3-step 配置为 2.99,分离式 2-step decode 配置为 2.5);
EVAL_ONLY运行则保留真实目标模型验证。
benchmarks/multi_node/srt-slurm-recipes/sglang/glm5.2/b200-fp4/agentic/,由新增的
launch_b200-dgxc.sh分支复制进 srt-slurm 检出目录,固定至 srt-slurmv1.0.53(217f94387abeddfed7149a71955dc523e07cd765)。SRT_SLURM_MODEL_PREFIX从glm5.2-fp4修正为glm-5.2-fp4,使其与配方声明的model.path一致——此模型前缀别名此前未被任何多机配置使用,因此该修正不影响现有条目。

Validation
process_changelog.pyagainst this diff generates six throughput jobs(four aggregate concurrency points, two disaggregated topologies) and two
AgentX eval jobs (one per disaggregated topology).
generate_sweep_configs.py test-configresolves both new config keys withno errors.
YAML parsing,
bash -non the launch script, andgit diff --checkallpass.
Golden synthetic-acceptance lengths (2.99 aggregate / 2.5 disaggregated)
match
golden_al_distribution/glm5.2_mtp.yaml.Synthetic acceptance is injected through the shared
inject_synthetic_acceptance.pylauncher helper, which is a no-op wheneverEVAL_ONLYis set, so eval runs keep real target-model verification.针对本次 diff 运行
process_changelog.py,生成六个吞吐任务(四个聚合并发点、两个分离式拓扑)和两个 AgentX eval 任务(每个分离式拓扑一个)。
generate_sweep_configs.py test-config可正确解析两个新增 config key,无报错。YAML 解析、launch 脚本的
bash -n,以及git diff --check均通过。Golden synthetic acceptance 长度(聚合 2.99 / 分离式 2.5)与
golden_al_distribution/glm5.2_mtp.yaml一致。Synthetic acceptance 通过共享的
inject_synthetic_acceptance.pylauncherhelper 注入,在设置
EVAL_ONLY时为 no-op,因此 eval 运行仍保留真实目标模型验证。

Overview
Adds AgentX agentic-coding benchmark coverage for GLM-5.2-NVFP4 on B200 via Dynamo + disaggregated or aggregated SGLang, wired to the new
cluster:b200-nscalerunner pool.Three checked-in srt-slurm recipes (
glm5.2-agentx-agg,1p2d,1p3d) define TP8 serving (EAGLE MTP, HiCache DRAM offload, NIXL KV transfer for disagg, KV router session affinity) and runagentic_srt.sh.nvidia-master.yamlregistersglm5.2-fp4-b200-dynamo-sglang-agentic-agg(concurrency 2/4/8/12) and…-disagg(1P2D and 1P3D at concurrency 113), pointing each sweep point at the matching recipe and enabling golden synthetic MTP acceptance only for throughput jobs.launch_b200-nscale-slurm.shnow acceptsglm5.2/fp4/dynamo-sglang/MTP, stagesGLM-5.2-NVFP4from node-local scratch, clones srt-slurm v1.0.53, copies the vendored recipes, and skips preflight like other large on-node weights.runners.yamlandperf-changelog.yamldocument the new cluster and config keys.Reviewed by Cursor Bugbot for commit 158aafc.
