- Check out DXML from DEC. It contains a whole bunch of BLAS routines optimized
- for the vector as well as scalar processors. The SPD contains a fairly good
- description of what's in there. Here's a small subset of the SPD:
-
- Digital Extended Math Library (DXML) is a set of mathematical
- subroutines drawn from public domain and proprietary libraries
- that are optimized for the VAX vector architecture. It includes
- the Basic Linear Algebra Subprograms (BLAS) Level 2 and BLAS
- Level 3 available from the Argonne National Labs. Also included
- are Digital proprietary subprograms for BLAS Level 1 Extensions
- and signal processing including one and two dimensional Fast
- Fourier Transforms (FFTs), Convolution, Correlation, and Digital
- Filters. These subprograms are highly optimized for the VAX
- Vector Architecture, but also support VAX scalar processing.
- Since DXML routines can be called from all languages that are
- supported by the VAX calling standards, the library permits
- access to VAX vector processing for applications written in
- other languages as well as FORTRAN or VAX MACRO.
