Scaffold a new evidence bundle directory ready for reproducibility-grade evidence capture: SOURCE.md (operator + cluster + git SHA + UTC timestamp), summary.md (verdict skeleton), commands/ (for the four-file .cmd/.stdout/.stderr/.exit tuple capture per shell…

SLA-first GPU capacity sizing for a serving deployment: given a tokens-per-minute (TPM) target AND the interactivity SLA (output tokens/s/user), compute the pods and GPUs needed from a model's measured tok/s/user-vs-concurrency curve. Sizing MUST start from…

Measure the low-concurrency (c=1..c=8) decode hot-path of a live vLLM pod FAST and CORRECTLY: where each token's time actually goes (GPU-busy vs host-idle gap vs comm), whether the workload is kernel-bound / host-bound / comm-bound, and what the addressable…

Capture per-kernel CUDA hardware-counter data (occupancy, achieved warps active, regs/thread, smem/block, DRAM throughput, arithmetic intensity, branch divergence %, warp-stall reason %) from a live vLLM inference pod via an `ncu` debug sidecar (no production…

Capture per-kernel CUDA profile data from a live vLLM inference pod via an nsys debug sidecar (no production image rebuild). Outputs `.nsys-rep` + summary CSV + top-kernels table that joins with the zymtrace per-kernel breakdown and the inference-perf-bench…

End-to-end orchestrator that takes a NEW model from a bare HuggingFace id to a perf-lake-published, validated CROSS-ENGINE (vLLM + SGLang) champion on B200/GB300. Scaffolds a per-model harness + evidence bundle (run-id == experiment-id), then drives…

Bridge between the inference-perf-bench / ai-bench output bundle and the profile-and-optimize perf-baseline registry. Knows the canonical inference perf metric shape (TTFT p50/p95/p99, ITL p50, throughput, tok/s/user, request latency p50, prefix cache hit…

Canonical inference perf-bench skill (formal name. The colloquial alias is `ai-bench` - identical behaviour). Drives NVIDIA AIPerf + the replay-playback dataset against an in-cluster vLLM endpoint to measure TTFT, ITL, throughput, tok/s/user, request latency,…

Fuse the four profilers -- nsys (timeline + kernel durations), ncu (roofline / occupancy / arithmetic intensity), zymtrace (CPU+GPU flamegraph), and DCGM (byte-grounded %SoL) -- into ONE ranked, data-backed recommendation ledger for a vLLM deployment. Every…

Build a multi-page benchmark report PDF (scatter panels + per-concurrency heatmap tables) from `vllm bench sweep serve_workload` and/or AIPerf outputs, in the GLM-5.1 reference layout (5x2 scatter facet by max_num_batched_tokens + 3x2 heatmap tables for…

Produce quantized inference weights from a BF16/FP8 base checkpoint via a post-training-quantization (PTQ) pipeline -- instead of only ever pulling NVFP4 weights pre-quantized. A calibration prep Job then a quantize Job: NVIDIA ModelOpt -> NVFP4 (default), or…

Search a vLLM serving model's config space for its best inference performance: a `perftunereport campaign_run` matrix sweep over concurrency x max_num_batched_tokens x kv-cache-dtype x cudagraph_mode, plus a same-node controlled A/B (`run-controlled-ab.sh`)…

Diff a current performance measurement against a registered baseline from the perf-baselines registry. Works for any measurement type (NCCL BW, MFU, step-time, latency, throughput, per-kernel times, structured heatmaps, nsys-rep profiles). Honors the…
Langue du texte source : anglais
Capture any performance measurement (NCCL bandwidth, MFU, step-time, latency, throughput, kernel-time, anything operator-defined) into a versioned baseline registry under experiments/artifacts/perf-baselines/. Workload-agnostic. Records full provenance…

Reusable wrapper for the knowledge-base-first SQL pattern, adapted to the zymtrace ClickHouse profiling backend. Operator names the metric / question / time range. Skill anchors the `zymtrace_profiling.events` schema first (DESCRIBE + label-value +…
