Transparency FAQ for BitBLAS

What is BitBLAS?

BitBLAS is a lightweight framework designed for generating high-performance CUDA/HIP code for BLAS (Basic Linear Algebra Subprograms) operators, emphasizing swizzling and layout propagation. It leverages a Domain-Specific Language (DSL), specifically TIR Script, to offer flexibility and efficiency in mathematical computations. BitBLAS aims to provide performance comparable to cuBLAS while introducing more flexibility and efficiency through its unique features.

What can BitBLAS do?

BitBLAS enhances the performance and flexibility of linear algebra computations with features like:

  • Auto Tensorization: Automatically optimizes code for various data types and operators, supporting FP16, INT8, and mixed precision operations.
  • Dynamic Symbolic Support: Facilitates kernel generation with dynamic shapes, enabling efficient computation for variable data sizes.
  • High-Performance Computing: Offers optimized performance for different data operations, including FP16xFP16, FP16xINT4/2/1, INT8xINT8, and INT8xINT4/2/1, among others.

What are BitBLAS's intended uses?

BitBLAS is intended for developers and researchers who require high-performance linear algebra computations in their CUDA/HIP-based applications. It is particularly beneficial for:

  • Machine Learning and Deep Learning: Accelerating training and inference computations.
  • Scientific Computing: Handling large-scale linear algebra operations efficiently.
  • High-Performance Computing (HPC): Enhancing performance in computationally intensive applications.

Data Handling and Privacy

This project is committed to protecting privacy and ensuring a secure environment for all users. It is designed with the following principles in mind:

  • No User Data Collection: The project does not collect, process, or store any personal or privacy-sensitive data from users. Users can utilize the project's features without the concern of their data being recorded or misused.

  • Transparency: We believe in complete transparency with our community. As such, we clearly state that no user data is collected or processed at any stage of the project's usage.

  • User Control and Privacy: Since the project does not involve user data, individuals retain full control over their information. Users can interact with the project knowing their privacy is safeguarded.
