Architecting for Hardware Diversity: Meta's End-to-End Co-Design for High-Performance AI Training on AMD GPUs

Meta’s paper details how the company optimizes AI training on AMD GPUs by co‑designing hardware and models, using an analytical performance model for kernel selection, and extending agentic workflows for microarchitecture‑aware optimizations. The authors compare AMD Instinct MI350X to NVIDIA B200 on a recommendation model, achieving up to 1.5× higher training throughput. Their methods, the first hyperscaler report on productionizing AMD GPUs for large‑scale training, have been incorporated into open‑source PyTorch, Triton, and ROCm.

KernelFoundry: Hardware-aware evolutionary GPU kernel optimization

KernelFoundry is a hardware‑aware evolutionary framework that optimizes GPU kernels by combining MAP‑Elites quality‑diversity search, meta‑prompt evolution, and template‑based parameter tuning. It generates SYCL and CUDA kernels, outperforming baseline methods with an average 2.3× speedup on KernelBench. The system is distributed, supports remote hardware access, and offers a flexible user interface for diverse real‑world kernel generation tasks.

KernelArc: A Multi-Agent Framework for GPU Kernel Optimization

KernelArc is a multi-agent framework designed to autonomously optimize GPU kernels across diverse workloads. It employs strategy-specialized agents that run concurrently, coordinating via conclusions-only shared memory, a deterministic benchmark guard, and read-only cross-agent state with plateau-triggered drafting. Evaluated on NVIDIA H100 and B200 GPUs with SOL-ExecBench workloads, KernelArc produced top-ranked implementations for tasks such as BF16 GEMM, cuBLASLt configuration tables, and various attention mechanisms, achieving first place on several leaderboard categories.
