3. DESCRIPTION OF PROGRAM OR FUNCTION

PC-BLAS is a highly optimized version of the Basic Linear Algebra Subprograms (BLAS), a standardized set of 38 routines that perform low-level operations on vectors of numbers in single- and double-precision real and complex  arithmetic.
Routines are included to find the index of the largest component of a vector, apply a Givens or modified Givens rotation, multiply a  vector by a constant, determine the Euclidean length, perform a dot  product, swap and copy vectors, and find the norm of a vector.

4. METHOD OF SOLUTION:

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The number of components in any vector and the spacing or stride between their entries must not exceed 32,767 (2**15-1). PC-BLAS will not work with an 80286 CPU operating in "protected" mode.
[ top ]
6. TYPICAL RUNNING TIME

The PC-BLAS routines can be 1.2 to 4 times as fast as their FORTRAN counterparts.
NESC9617/01
NEA-DB ran the program on an IBM PC/AT microcomputer. BUST required 3 minutes; MATETSTP required 13 minutes.
[ top ]
7. UNUSUAL FEATURES OF THE PROGRAM

The BLAS have been carefully written to minimize numerical problems such as loss of precision and underflow and are designed so that the computation is independent of the interface with the calling program. This independence is achieved through judicious use of Assembly language macros.

8. RELATED AND AUXILIARY PROGRAMS

An initial release of PC-BLAS received from Steve Langer of Lawrence Livermore National Laboratory, was optimized for Microsoft Fortran compiler use. Portable FORTRAN versions of the BLAS are included in LINPACK (NESC 800).

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

Because of the complexity of their specifications and the fact that they do  not normally appear in the inner loop of a linear algebra computation, subroutines SROTMG and DROTMG are provided in FORTRAN.  An auxiliary program, BUST, is included to separate the single large source file distributed into several smaller files.
Interfaces are provided for Lahey Fortran 77, Microsoft Fortran 77  and Ryan-McFarland IBM Professional Fortran.
