HP MLIB for Itanium Linux Version 9.6.1 Release Note

What’s in This Version

HP MLIB for Itanium Linux Version 9.6.1 Release Note8

Benefits and Features

HP MLIB for Itanium® Linux Version 9.6.1 incorporates algorithmic improvements and

several tunable parameter adjustments for improved execution performance. VECLIB is

optimized by using highly-efficient implementations of both dense and sparse BLAS—levels 1,

2, and 3. LAPACK fully conforms with the public-domain version 3.0 of LAPACK. The key

computational kernels in LAPACK are optimized to take full advantage of the respective

architecture. The HP version of ScaLAPACK is tuned and built with HP Message Passing

Interface (MPI) V2.2 and fully conforms to V1.7.5 of the ScaLAPACK standard. (Refer to

http://www.hp.com/go/mpi for information on the HP-MPI product.) This implementation

provides the SuperLU_DIST V2.0 library designed for solving non-symmetric sparse linear

systems on distributed memory systems.

VECLIB

VECLIB is a collection of Fortran-callable subprograms, providing mathematical software and

computational kernels for engineering and scientific application programs. This library

contains subprograms for

• Dense vector operations, including the Level 1 BLAS

• Matrix operations, including the Level 2 and Level 3 BLAS

• CXML BLAS extensions

Compaq Extended Math Library (CXML) is a collection of routines that performs

numerically intensive operations that occur frequently in engineering and scientific

computing, such as linear algebra and signal processing.
