HP MLIB for Itanium Linux Version 9.6 Release Note
What’s in This Version
HP MLIB for Itanium Linux Version 9.6 Release Note8
Benefits and Features
HP MLIB for Itanium® Linux Version 9.6 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 V1.7.4 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.
HP MLIB for Itanium® Linux Version 9.6 incorporates algorithmic improvements, and
several tunable parameters have been adjusted for improved execution performance. Features
in this version include
• VECLIB
• LAPACK
• ScaLAPACK
• Distributed SuperLU
• SOLVERS
•VMATH
• SMP Parallelism
• MPI Parallelism
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.
