HREF="node29.html#UMFPACK">9</A>]
A sparse LU factorization package included in the SuiteSparse library, available from
<TT><A NAME="tex2html5"
HREF="faculty.cse.tamu.edu/davis/suitesparse.html">faculty.cse.tamu.edu/davis/suitesparse.html</A></TT>;
it provides sequential factorization and triangular system solution for double
precision real and complex data. We tested version 4.5.4 of SuiteSparse.
Note that for configuring SuiteSparse you should provide the right path to the BLAS
and LAPACK libraries in the <code>SuiteSparse_config/SuiteSparse_config.mk</code> file.
HREF="node30.html#blas3">11</A>,<A
HREF="node30.html#blas2">12</A>,<A
HREF="node30.html#blas1">17</A>] Many vendors provide optimized versions
of BLAS; if no vendor version is
available for a given platform, the ATLAS software
(<TT><A NAME="tex2html1"
HREF="math-atlas.sourceforge.net">math-atlas.sourceforge.net</A></TT>)
may be employed. The reference BLAS from Netlib
(<TT><A NAME="tex2html2"
HREF="www.netlib.org/blas">www.netlib.org/blas</A></TT>) are meant to define the standard
behaviour of the BLAS interface, so they are not optimized for any
particular plaftorm, and should only be used as a last
resort. Note that BLAS computations form a relatively small part of
the MLD2P4/PSBLAS computations; they are however critical when using
preconditioners based on MUMPS, UMFPACK or SuperLU third party
libraries. Note that UMFPACK requires a full LAPACK library; our
experience is that configuring ATLAS for building full LAPACK does not
work in the correct way. Our advice is first to download the LAPACK tarfile from
<TT><A NAME="tex2html3"
HREF="www.netlib.org/lapack">www.netlib.org/lapack</A></TT> and install it independently of ATLAS. In this case,
you need to modify the OPTS and NOOPT definitions for including -fPIC compilation option
in the make.inc file of the LAPACK library.

A sparse LU factorization package available from <TT><A NAME="tex2html6"
HREF="mumps.enseeiht.fr">mumps.enseeiht.fr</A></TT>;
it provides sequential and parallel factorizations and triangular system solution
for single and double precision, real and complex data.
We tested versions 4.10.0 and 5.0.1.

<DT><STRONG>SuperLU</STRONG></DT>

A sparse LU factorization package available from

factorization and triangular system solution for single and double precision,
real and complex data. We tested versions 4.3 and 5.0. If you installed BLAS from
ATLAS, remember to define the BLASLIB variable in the make.inc file.

<DD>[<A
HREF="node29.html#SUPERLUDIST">18</A>]
A sparse LU factorization package available
from the same site as SuperLU; it provides parallel factorization and
triangular system solution for double precision real and complex data.
We tested versions 3.3 and 4.2. If you installed BLAS from
ATLAS, remember to define the BLASLIB variable in the make.inc file and
to add the <code>-std=c99</code> option to the C compiler options.
Note that this library requires the ParMETIS
library for parallel graph partitioning and fill-reducing matrix ordering, available from
<TT><A NAME="tex2html8"
HREF="glaros.dtc.umn.edu/gkhome/metis/parmetis/overview">glaros.dtc.umn.edu/gkhome/metis/parmetis/overview</A></TT>.

available from <TT><A NAME="tex2html4"
HREF="www.ce.uniroma2.it/psblas">www.ce.uniroma2.it/psblas</A></TT>; version
3.5.0 (or later) is required. Indeed, all the prerequisites
listed so far are also prerequisites of PSBLAS.
