BLAS stands for Basic Linear Algebra Subprograms. It is a specification that provides a set of low-level routines for performing common linear algebra operations such as vector and matrix-matrix multiplication, vector operations, and solving linear systems. BLAS routines are highly optimized for performance and are often implemented in a way that takes advantage of specific hardware features (like SIMD instructions or multi-threading).
BLAS can be divided into three levels:
1. **Level 1 BLAS**: Operations on vectors, such as dot products and vector norm calculations, which are primarily considered element-wise operations.
2. **Level 2 BLAS**: Operations involving matrices and vectors, such as matrix-vector multiplication.
3. **Level 3 BLAS**: Operations on matrices, which involve matrix-matrix multiplication and other related routines.
BLAS is a foundational library in many high-performance computing environments and serves as the backend for more complex numerical libraries, such as LAPACK (Linear Algebra PACKage), which focuses on solving linear systems and eigenvalue problems. Many software packages and frameworks, especially those used in scientific computing and machine learning, utilize BLAS for efficient linear algebra computations. Popular implementations of BLAS include ATLAS, OpenBLAS, MKL (Intel Math Kernel Library), and BLIS.
