HP MLIB for PA-RISC and Itanium HP-UX Version 9.5.6 Release Note

What’s in This Version

MLIB contains new VECLIBSC8 and LAPACKSC8 libraries as described in the VECLIB

section above.

Although LAPACK was designed for use with Fortran programs, C programs may call

LAPACK subprograms, as described in Appendix A of the HP MLIB User's Guide.

ScaLAPACK

ScaLAPACK is a library of high-performance linear algebra routines capable of solving

systems of linear equations, linear least squares problems, eigenvalue problems, and singular

value problems. ScaLAPACK can also handle many associated computations such as matrix

factorizations or estimating condition numbers.

ScaLAPACK is public domain software that was developed by Oak Ridge National Laboratory.

It is design for distributed computing and uses MPI for parallelism. The ScaLAPACK library

routines are callable from Fortran and C routines.

Distributed SuperLU

This implementation provides the SuperLU_DIST library designed for distributed memory

parallel computers. It is based on the public-domain SuperLU_DIST, which was developed at

the Lawrence Berkeley National Lab and the University of California at Berkeley. The library

contains a set of subroutines to solve non-symmetric sparse linear systems. The library is

implemented in ANSI C, using HP-MPI for communication. The library includes routines to

handle both real and complex matrices using double precision.

The routines can be called directly from C applications. They may also be called from Fortran

applications, however, “bridge” routines (in C) must be supplied. For details about creating

bridge routines, please refer to Section 2.9.2 in the SuperLU User’s Guide available at

http://www.nersc.gov/~xiaoye/SuperLU.

SOLVERS

SOLVERS is a collection of direct sparse linear system solvers and graph partitioning

routines. Symmetric systems and structurally-symmetric systems can be solved using SMP

parallelism. These routines have been optimized for use on Hewlett-Packard servers. Features

are:

• Sparse symmetric and structurally-symmetric linear equation solutions.

• Sparse symmetric ordinary and generalized eigensystems solutions.

• Full METIS functionality

This implementation provides the METIS Version 4.0 library. It is based on the

public-domain METIS, which was developed at the University of Minnesota, Department

of Computer Science, and the Army HPC Research Center. The library contains a set of
