SparseDitto: An Agentic Sparse Compilation Framework through Architecture-Aware Synthesis on GPUs

SparseDitto is an agentic sparse compilation framework that jointly synthesizes representation, execution schedule, and hardware mapping for sparse matrix computations on GPUs. It uses structural analysis, a learned template-ranking prior, and LLM-guided lowering to generate CUDA code, with target-GPU profiling refining the plan. The framework supports multiple operators such as SpMV, SpMM, and SpGEMM, adapts to different hardware, and achieves significant speedups over cuSPARSE, including up to 146.61× on certain matrices and 3.39× acceleration for full-batch GCN training.

GPU-CFR: 80x Faster Counterfactual Regret Minimization by Compiling the Game to Static Dataflow and CUDA Graph Replay

GPU-CFR is a compiler and runtime that transforms any counterfactual regret minimization (CFR) game into a static dataflow representation, eliminating variable kernel launches by precomputing indices, flat arrays, and depth‑level execution blocks. This approach reduces framework operations by up to 18.1× and allows a single CUDA Graph Replay to execute each iteration, yielding 29.8–80.4× speedups over the fastest prior GPU CFR on an A100 and 14–258× over the LiteEFG CPU implementation for large games. The compiled representation alone delivers 2.2–51.1× acceleration on eight CPU threads, while the optimized path reproduces reference iterates exactly and pays for its overhead within the first solve.

GPU-CFR: 80x Faster Counterfactual Regret Minimization by Compiling the Game to Static Dataflow and CUDA Graph Replay

GPU-CFR compiles a fixed game into static dataflow, eliminating per-iteration kernel launches and reducing framework operations by up to 18.1×. On an A100 GPU it achieves 29.8–80.4× speedups over the fastest prior GPU CFR and 14–258× over the LiteEFG CPU implementation for large games. The compiled representation alone delivers 2.2–51.1× acceleration on eight CPU threads, while the CUDA Graph Replay enables a single graph launch per iteration.

TrainBridge: Agentic NPU Training Optimization Guided by GPU Compilation Evidence

TrainBridge is an agentic approach that transfers optimization guidance from GPU training to Ascend NPU training. It extracts optimization intents from highly optimized GPU execution and uses them to rewrite NPU programs, then refines these rewrites through iterative profiling. Experiments show that TrainBridge yields an average 1.7× speedup across four workloads and nearly 2.0× speedup on 27 Modded‑NanoGPT speedrun records.

Dissecting GPU Utilization for LLM Inference on Nvidia Hopper

The paper investigates how a single SM utilization metric can misrepresent the true workload of large language model (LLM) inference on Nvidia Hopper GPUs. By profiling vLLM with FlashAttention‑3 and cuBLASLt on an H100 NVL across various phases (cold prefill, warm prefill, and decode) and varying sequence length and batch size, the authors replace the single utilization figure with eight detailed counter‑validated views. These views, tied to specific Nsight Compute counters or formulas, reveal how factors such as fragment fill, occupancy limits, stall signatures, wave quantization, and kernel selection create utilization gaps across four production models and six per‑layer kernel roles.
