What does BLAS mean in MATHEMATICS

What is BLAS?

BLAS stands for Basic Linear Algebra Subprograms. It is an extensive library of subprograms designed to efficiently perform common linear algebra operations such as matrix multiplication and vector addition on large matrices or vectors. BLAS features optimized functions for performing these tasks on various types of hardware architectures including shared memory systems, distributed memory systems, vector supercomputers, GPU-accelerated systems and so on. It provides highly efficient baseline implementations of fundamental linear algebra tasks that can be further optimized for specific hardware architectures or application requirements.

Benefits

The primary benefit of using BLAS lies in its ability to improve performance by offloading work from the CPU onto specialized hardware like GPUs. By using BLAS library functions instead of manually written functions, developers gain access to highly efficient implementations that have been tested across many different types of hardware platforms. Additionally, utilizing BLAS make the task easier since developers only need to write the code once rather than having to implement multiple functions for different hardware architectures thus allowing one code base which can be reused across platforms with minimal effort.
