The BLAS (Basic Linear Algebra Subroutines) are high-quality building block routines for performing basic vector and matrix operations. Level 1 BLAS do vector-vector operations, Level 2 BLAS do matrix-vector operations, and Level 3 BLAS do matrix-matrix operations.
Blacklight and Salk Usage
On blacklight and salk, the BLAS are imbedded in MKL and SCSL(SGI Scientific Computing Software Library)
For the BLAS imbedded in SCSL, see the man pages:
or see the SCSL User's Guide.
For the BLAS in MKL, see the MKL documentation.
