## Short Segments
Thinking Machines Lab advocates for AI that adapts to its users, not the other way around. Their latest report argues for customizable AI models that extend human judgment, challenging the current norm where AI is trained in limited settings and then frozen. The lab proposes four technical directions: developing strong, multimodal models; enabling user-driven fine-tuning; creating interfaces for better human-machine communication; and sharing research to broaden understanding. This approach aims to make AI more inclusive and aligned with user needs, potentially transforming how AI is integrated into daily life.
## Feature Story
NVIDIA's Tile-Based GPU Programming is reshaping how developers approach high-performance computing. This tutorial dives into the practicalities of using NVIDIA's TileGym for GPU programming, offering a hands-on Colab workflow that adapts to various hardware conditions. The core idea is to shift from single-thread coding to operating on entire data tiles, which are loaded into the kernel, computed on, and then stored back efficiently. Tile-based programming, introduced with NVIDIA CUDA 13.1, allows developers to write algorithms at a higher level, abstracting away the complexities of specialized hardware like tensor cores. This approach is particularly beneficial for AI workloads, where matrix multiplication and attention mechanisms are crucial. By using tile-based abstractions, developers can optimize GPU kernels within large C++ codebases, leveraging the advanced capabilities of NVIDIA hardware. The tutorial begins with a CUDA environment probe, checking for the presence of NVIDIA cuTile and falling back to Triton when necessary. This flexibility ensures that the workflow can run across different hardware setups, making it accessible to a broader range of developers. The tutorial covers implementing vector addition, fused GELU, row-wise softmax, tiled matrix multiplication, and flash attention, with results benchmarked against PyTorch for accuracy. One of the key advantages of tile-based programming is its ability to simplify the development process. Traditionally, writing a competitive matrix multiplication kernel for tensor cores required extensive knowledge of CUDA C++, including warp synchronization and shared memory tiling. With NVIDIA's new approach, developers can achieve similar performance with significantly less code and complexity. This shift is part of a broader trend towards making high-performance computing more accessible. By providing a top-level language layer and an intermediate layer that any high-level programming language can target, NVIDIA is lowering the barrier to entry for developers looking to harness the power of GPUs. This democratization of GPU programming could lead to more innovation and faster development cycles in AI and other computationally intensive fields. Looking ahead, NVIDIA plans to expand support for CUDA Tile across more GPU architectures, starting with Ampere, Ada, and Blackwell. This expansion will further enhance the flexibility and reach of tile-based programming, allowing more developers to take advantage of its benefits. In conclusion, NVIDIA's Tile-Based GPU Programming represents a significant advancement in how developers can leverage GPU power. By simplifying the programming model and making it more accessible, NVIDIA is paving the way for more efficient and innovative use of GPUs in AI and beyond. As support for this technology grows, it will be interesting to see how it influences the development of future AI applications and other high-performance computing tasks.
