AI Performance Engineering

AI Performance Engineering

A curated resource list for learning GPU performance engineering and production inference.

The list is ordered from a single inference request to a single GPU, optimized kernels, inference engines, and distributed systems. Read Start here first. After that, use it as a reference.

The core list uses original papers, official specifications and documentation, creator repositories, and direct implementation work.

If you work on these problems, Wafer is hiring.

Contents

Start here: the minimum mental model

Read these in order if you are new to the field.

  1. How to Scale Your Model: Inference - One request from prefill through decode, with batching, KV memory, and parallelism.
  2. Attention Is All You Need - The transformer computation that the rest of the list optimizes.
  3. CUDA C++ basics - The shortest official introduction to the CUDA execution model.
  4. Programming Massively Parallel Processors - The main textbook for GPU programming, memory, and kernel design.
  5. Roofline: An Insightful Visual Performance Model - The compute, memory-bandwidth, and arithmetic-intensity model.
  6. Transformer Inference Arithmetic - FLOPs, parameter bytes, KV bytes, and communication for transformer inference.
  7. Efficiently Scaling Transformer Inference - Latency, memory, and parallelism costs for large-model inference.
  8. Etalon - TTFT, TPOT, goodput, and latency SLOs for generative-model serving.

For a practical companion, use the GPU Mode lectures.

6. Current hardware

Read each architecture with its ISA or tuning guide. Vendor peak numbers are not performance measurements.

NVIDIA

AMD

Google TPU

AWS Trainium

Frontier

Verified on 2026-08-23. This section is kept separate from the core list because the evidence changes quickly.

AI-generated kernels

  • KernelBench - The original benchmark for converting PyTorch operators into faster GPU kernels.
  • KernelBench-Verified - Stronger correctness tests and baseline parity.
  • SOL-ExecBench - Correctness and performance measured against a hardware speed-of-light model.

Watchlist

  • NVIDIA Rubin and Rubin CPX, pending shipped systems and reproducible measurements.
  • AMD MI400, CDNA 5, and Helios, pending architecture and ISA documents.
  • Session-aware and agentic scheduling against public production traces.
  • Real-time voice and video serving with complete quality and latency metrics.
  • Inference ASICs, processing in memory, analog compute, and photonic compute with reproducible deployments.
  • Individual AI kernel agents that have not been rerun on a hardened evaluator.

Source policy

A core source must be one of the following:

  • the paper that introduced the mechanism;
  • the specification or official documentation that defines it;
  • the repository that implements it;
  • a direct implementer report with code, measurements, and enough detail to reproduce the result.

Performance claims need the hardware, workload, precision, baseline, and correctness method. Otherwise the number is omitted.
