Concepts behind "throughput"
Review the concepts used in these questions.
Foundational
Latency Metrics: TTFT, TPOT and GoodputRead a stream from its timestamps: distinguish first-token wait, individual gaps and average generation pace. Compute goodput with explicit deadlines, denominators and failure accounting.🚀 Inference & Serving
Foundational
Serving Benchmarks That Do Not LieDesign reproducible serving experiments with realistic arrivals, cache state and failure accounting. Interpret latency-qualified throughput and conditional per-rank bounds without turning optimistic kernel estimates into production capacity.🧮 Open Weights & Serving Engines
Core
Tensor Cores and Matrix UnitsTensor cores accelerate supported matrix multiply-accumulate operations. Their performance depends on precision, matrix shape and how efficiently the kernel supplies data.🧩 GPU & Accelerator ArchitectureSign in
Core
MFU and HFUMeasure useful model work, separate recomputation, and align token counts, timing and hardware peaks. Learn what activity counters can and cannot tell you.🕸️ Distributed TrainingSign in
Core
Continuous BatchingContinuous batching changes which requests run between model iterations. Learn how a waiting request joins, why an empty slot is not enough, and how to balance throughput against each user’s token latency.🚀 Inference & ServingSign in
Advanced
Bandwidth-Bound Decode ThroughputEstimate decode throughput from bytes per step, then separate aggregate output from per-user pace. A finite-memory example shows how batching, cache reads and quantization change the bound.🧮 Napkin Math & Capacity🔒 Premium
