HREF="node29.html#blas2">12</A>,<A

HREF="node29.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.

Please note that the four previous libraries must have Fortran

interfaces compatible with MLD2P4;

usually this means that they should all be built with the same

compiler as MLD2P4.
