About this CFP

What is Build on Trainium?

Build on Trainium is a $110MM credit program focused on AI research and university education to support the next generation of innovation and development on AWS Trainium. AWS Trainium chips are purpose-built for high-performance deep learning (DL) training of generative AI models, including large language models (LLMs) and latent diffusion models. Build on Trainium provides compute credits to novel AI research on Trainium, investing in leading academic teams to build innovations in critical areas including new model architectures, ML libraries, optimizations, large-scale distributed systems, and more. This multi-year initiative lays the foundation for the future of AI by inspiring the academic community to utilize, invest in, and contribute to the open-source community around Trainium. Combining these benefits with Neuron software development kit (SDK) and recent launch of the Neuron Kernel Interface (NKI), AI researchers can innovate at scale in the cloud.

What are AWS Trainium and Neuron?

AWS Trainium is an AI chip developed by AWS for accelerating building and deploying machine learning models. Built on a specialized architecture designed for deep learning, Trainium accelerates the training and inference of complex models with high output and scalability, making it ideal for academic researchers looking to optimize performance and costs. This architecture also emphasizes sustainability through energy-efficient design, reducing environmental impact. Amazon has established a dedicated Trainium research cluster featuring up to 40,000 Trainium chips, accessible via Amazon EC2 Trn1 instances. These instances are connected through a non-blocking, petabit-scale network using Amazon EC2 UltraClusters, enabling seamless high-performance ML training. The Trn1 instance family is optimized to deliver substantial compute power for cutting-edge AI research and development. This unique offering not only enhances the efficiency and affordability of model training but also presents academic researchers with opportunities to publish new papers on underrepresented compute architectures, thus advancing the field.

Focus on Kernels for ML Acceleration

  1. GenAI for Kernel Development: As kernel development becomes increasingly complex and specialized for accelerators like Trainium, generative AI offers opportunities to automate and optimize the kernel development lifecycle. We seek proposals that leverage GenAI to accelerate kernel creation, optimization, and maintenance on Trainium, including:
    1. Automated Kernel Generation: Methods for using GenAI to generate high-performance NKI kernels from high-level specifications, including natural language descriptions, mathematical formulations, or reference implementations in other frameworks. This includes agentic workflows leveraging reinforcement learning, inference-time compute scaling, and multi-agent systems with iterative refinement where agents execute kernels, observe performance metrics, and progressively improve implementations through feedback loops.
    2. Kernel Optimization and Tuning: Techniques for using GenAI to automatically optimize existing kernels, including instruction scheduling, memory access patterns, tile size selection, and register allocation strategies. This encompasses knowledge distillation and memory systems that capture, distill, and organize optimization insights into structured knowledge bases of architecture-specific heuristics, enabling continuous learning from both successful and failed optimization attempts.
    3. Performance Debugging and Analysis: AI-assisted tools for identifying performance bottlenecks, suggesting optimizations, and explaining performance characteristics of NKI kernels. This includes methods for correctness verification and robustness testing that rigorously verify functional correctness beyond standard test cases, detecting subtle bugs and reward hacking behaviors where kernels achieve favorable metrics while producing incorrect outputs.
    4. Code Completion and Synthesis: Methods for intelligent code completion, pattern recognition, and synthesis of common kernel idioms specific to NKI and Trainium architecture. This includes transfer learning and domain adaptation techniques for adapting kernel generation across different hardware generations or compiler versions with minimal training data, as well as explain ability methods that make AI-generated kernels interpretable and maintainable through documentation generation and collaborative human-AI development workflows.
    5. Benchmark Construction and Evaluation: Development of comprehensive, representative benchmark suites for evaluating kernel generation and optimization techniques on Trainium, including systematic methodologies for creating diverse kernel collections spanning operator types, tensor shapes, data layouts, and compute/memory-bound characteristics representative of real-world model workloads.
  2. Developer Tools and Profiling: Effective kernel development requires sophisticated tooling for understanding performance, debugging behavior, and iterating designs. We seek proposals that advance the NKI developer experience on Trainium, including:
    1. Novel Profiling Visualizations and Human-Computer Interaction: Innovative visualization techniques that blend performance analysis with HCI research to make complex kernel behavior intuitive and actionable, including interactive 3D performance landscapes, temporal execution flow visualizations, comparative visual analytics across kernel variants, attention-driven bottleneck highlighting, and multi-dimensional performance space exploration tools that enable developers to quickly identify optimization opportunities through visual pattern recognition.
    2. Performance Modeling and Estimation: Advanced methods for predicting kernel performance before execution, including analytical roofline models extended for Trainium architecture, learned performance predictors using neural networks trained on kernel characteristics, hybrid symbolic-numeric performance models, static analysis techniques for estimating memory bandwidth and compute utilization, and probabilistic performance bounds that account for hardware variability and dynamic effects.
    3. Debugging and Verification Tools: Methods for validating kernel correctness, detecting numerical issues, and debugging complex kernel behaviors, including symbolic execution and formal verification approaches.
    4. Interactive Development Environments: Enhanced IDE support for NKI development, including syntax highlighting, type checking, inline performance hints derived from real-time estimation models, and integration with existing development workflows.
  3. Kernel Porting and Cross-Framework Translation: The ecosystem of kernel languages continues to fragment, creating barriers to adoption and limiting code reuse. We seek proposals that enable seamless translation between kernel frameworks while preserving high performance on Trainium, including:
    1. Automated Kernel Translation: Methods for automatically porting kernels from other frameworks (Triton, CUDA,CuTe, Pallas) to NKI specifically while maintaining or improving performance, including semantic-preserving transformations and architecture-specific optimizations
    2. Cross-Framework Optimization: Methods for leveraging optimization techniques across different kernel languages, including pattern matching, optimization transfer learning, and unified intermediate representations.
    3. Performance Portability: Approaches for ensuring translated kernels achieve competitive performance with hand-written implementations, including auto-tuning, architecture-aware code generation, and performance validation frameworks.
  4. Kernel Language Design and Abstractions: The design of kernel languages fundamentally shapes developer productivity and achievable performance. We seek proposals that explore novel language representations, APIs, and abstractions for NKI on Trainium, including:
    1. Alternative Language Representations: Novel representations for expressing kernel computations, including tensor comprehensions, polyhedral models, and domain-specific languages that improve expressiveness or enable better optimization.
    2. API Design and Primitives: Improved APIs and primitive operations for kernels including higher-level abstractions that maintain performance while improving usability, composability, and maintainability.
    3. Abstraction Layers: Methods for building layered abstractions that allow developers to work at different levels of detail, from high-level operations to low-level hardware control, with smooth transitions between levels.
