Accelerated Fourier SAT (AFSAT) is a GPU-accelerated solver for pseudo-Boolean satisfiability using continuous local search. It significantly improves numerical stability, runtime performance, and memory efficiency over its proof-of-concept by leveraging JAX for parallel processing and addressing memory/floating-point limitations.
The article posits that modern AI, particularly large models, is fundamentally reliant on expensive, centralized GPU infrastructure, making it "someone else's GPU" rather than local compute. It critiques this centralization, highlighting concerns about control, cost, and environmental impact.
This article details the creation of a bit-accurate Triton kernel for Qwen 2.5, fusing QKV projection, RoPE, and KV cache write into a single GPU launch. It achieves a 4.5-5x speedup over multiple PyTorch operations while maintaining exact output accuracy, with the post explaining its design and benchmarking.
This paper introduces FastSinkhorn, a native CUDA implementation of the log-domain Sinkhorn algorithm that provides faster and more stable solutions for optimal transport (OT) problems. It achieves a 12x speedup over the POT library and 5.9x over GPU-accelerated PyTorch baselines, maintaining numerical stability for small regularization parameters.
This guide explains how running AI models on GPU cloud servers can significantly speed up training and inference tasks. It covers server selection and model deployment, detailing why GPUs excel at the parallel computations required for deep learning compared to CPUs.
