The following base libraries are needed:
|
|
<DL>
|
|
<DT><STRONG>BLAS</STRONG></DT>
|
|
<DD>[<A
|
|
HREF="node25.html#blas3">11</A>,<A
|
|
HREF="node25.html#blas2">12</A>,<A
|
|
HREF="node25.html#blas1">19</A>] Many vendors provide optimized versions
|
|
of the Basic Linear Algebra Subprograms; if no vendor version is
|
|
available for a given platform, the ATLAS software
|
|
(<code>http://math-atlas.sourceforge.net/</code>)
|
|
may be employed. The reference BLAS from Netlib
|
|
(<code>http://www.netlib.org/blas</code>) 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 the UMFPACK or SuperLU third party
|
|
libraries.
|
|
</DD>
|
|
<DT><STRONG>MPI</STRONG></DT>
|
|
<DD>[<A
|
|
HREF="node25.html#MPI2">18</A>,<A
|
|
HREF="node25.html#MPI1">23</A>] A version of MPI is available on most
|
|
high-performance computing systems;
|
|
|
|
</DD>
|
|
<DT><STRONG>PSBLAS</STRONG></DT>
|
|
<DD>[<A
|
|
HREF="node25.html#PSBLASGUIDE">15</A>,<A
|
|
HREF="node25.html#psblas_00">17</A>] Parallel Sparse BLAS is
|
|
available from
|
|
<BR><code>http://www.ce.uniroma2.it/psblas</code>; version
|
|
3.3 (or later) is required. Indeed, all the prerequisites
|
|
listed so far are also prerequisites of PSBLAS.
|
|
</DD>
|
|
</DL>
|
|
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.
