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.

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.

GRADSOLVE is an open‑source JAX library that provides fast, exact reverse‑mode gradients for low‑dimensional ordinary differential equation (ODE) ensembles on NVIDIA GPUs. It records the accepted steps of an adaptive solver and differentiates a fixed‑step replay, yielding the exact discrete adjoint at a lower computational cost than traditional checkpointed methods. Benchmarks show that GRADSOLVE’s forward kernel is 2.8× faster than DiffEqGPU.jl, and its gradient computation is 5.6–14.1× faster than Diffrax’s checkpointed adjoint while maintaining matched forward‑state accuracy across multiple GPU generations.

arXiv:2607. 24762v1 Announce Type: new Abstract: Machine learning models are increasingly embedded in everyday software, and most of their runtime is spent in a small set of compute kernels such as matrix multiplication, convolution, and normalization.
