Overview

The BLAS (Basic Linear Algebra Subprograms) are routines that provide standard building blocks for performing basic vector and matrix operations. The BLAS operations are split into 3 groups:

• Level 1: scalar, vector and vector-vector operations,

• Level 2: matrix-vector operations, and

• Level 3: matrix-matrix operations.

NVPL BLAS provides:

• Standard Fortran 77 BLAS operations,

• Some non-standard operation extensions, like Batched GEMM operations,

• C interfaces for the operations mentioned above (also known as CBLAS), and

• Service functions (such as threading control), available in C and Fortran.
