VSL: A New Zero-Dependency, High-Performance Library for V Language's Scientific Computing and AI Development

This article introduces VSL—a V language-based scientific computing library that provides pure V implementations of BLAS/LAPACK, machine learning algorithms, and GPU acceleration, offering new ideas for zero-dependency deployment and high-performance computing.

In the fields of scientific computing and artificial intelligence, Python has long dominated with libraries like NumPy, SciPy, and PyTorch. However, Python's performance bottlenecks and deployment complexity have always been pain points in production environments. In recent years, languages like Rust, Julia, and Zig have tried to challenge this landscape, and V language (Vlang) along with its ecosystem's VSL library has also joined this competition.

VSL (V Scientific Library) is a scientific computing library designed specifically for the V language, aiming to provide a full set of tools needed for AI development and high-performance scientific computing. Its unique features include: 100% pure V implementation of BLAS/LAPACK kernels, zero external dependencies, and performance that competes with optimized C libraries.

Before diving into VSL, it's necessary to understand the characteristics of its host language V. V is a statically compiled language whose design philosophy emphasizes simplicity, speed, and safety:

• Extremely fast compilation: V's compiler can compile hundreds of thousands of lines of code in less than a second
• Memory safety: No null pointers, no dangling pointers, no data races
• C language interoperability: Can directly call C libraries, facilitating integration with existing ecosystems
• Concise syntax: A fusion of Go and Rust, with a gentle learning curve
• Single-file executable: Compiled output has no runtime dependencies

These features make V an ideal candidate for systems programming and scientific computing, and VSL is the concrete realization of this vision in compute-intensive fields.

VSL provides a rich set of mathematical and computational modules covering multiple dimensions of scientific computing:

As the cornerstone of scientific computing, VSL's linear algebra module provides:

• Complete matrix and vector operations
• Eigenvalue decomposition
• Linear equation solvers
• Matrix decomposition algorithms such as QR decomposition, LU decomposition, and SVD

It is particularly worth noting that VSL implements pure V versions of BLAS (Basic Linear Algebra Subprograms) and LAPACK (Linear Algebra PACKage), which are the two most fundamental and widely used libraries in the field of numerical computing. Traditionally, these libraries are written in Fortran, and Python's NumPy and SciPy both rely on their backend implementations.

VSL has built-in various classic machine learning algorithms:

• Clustering: K-means algorithm
• Classification: K-Nearest Neighbors (KNN)
• Regression: Linear regression, logistic regression
• NLP tools: Basic text processing functions

Although it does not yet provide a deep learning framework, these implementations are sufficiently practical for traditional ML tasks and prototype development.
