<h1>Interface to Other Software</h1>

<h2>Linear Algebra</h2>

<p>At present time, GA toolkit contains interfaces to linear algebra
libraries:</p>

<ul>
    <li><a href="http://www.netlib.org/scalapack/index.html" title="Offsite link to The ScaLAPACK Project website">ScaLAPACK</a></li>
    <li><a href="peigs.html">PeIGS</a> parallel eigensolver library</li>
    <li><a href="http://www.cs.utexas.edu/users/rvdg/abstracts/SUMMA.html" title="Offsite link to SUMMA: Scalable Universal Matrix Multiplication Algorithm website">SUMMA</a> parallel matrix multiplication</li>
    <li><a href="petsc.html">PETSc</a> partial differential equation solvers</li>
</ul>

<h2>Computational Steering and Visualization</h2>

<ul>
    <li><a href="cumulvs.html">CUMULVS:</a> a software framework that enables
    programmers to incorporate fault-tolerance, interactive visualization and
    computational steering into existing parallel programs.</li>
</ul>

<h2>Message Passing</h2>

<p>The current implementation of the GA toolkit is configurable to run with
either the
<a href="http://www.mcs.anl.gov/mpi/index.html"
    title="Offsite link to MPI standard website">MPI</a>
(Message Passing Interface) or
<a href="/tcgmsg/">TCGMSG</a>
portable message passing libraries. The GA could also be adopted to work with
PVM.</p>

<p>As a convenience to the programmer, GA provides its own interface to
<em>broadcast</em> and <em>reduce</em> collective operations insensitive to the
selection of the message-passing library.</p>

<h2>Other Software</h2>

<p>Some of the GA operations use the <a href="/ma/">MA</a>,
a portable memory allocator library developed at Pacific Northwest National
Laboratory.</p>
