<h2>Clustered GRASS GIS</h2>

GIS related work is regularly CPU-intensive - as CPU power becomes cheaper
nowadays, GRASS might be run in clustered environments. There are several
options to parallelize GRASS:

<ul>
<li><a href=http://openmosix.sourceforge.net/>openMOSIX</a>: To run GRASS
on an openMOSIX cluster,
there is no need to modify GRASS or to link with any library, or even
to assign processes to different nodes. You can run GRASS in parallel
sessions (same location, different mapsets) which will be sent to the
various cluster nodes.
However, individual modules will be run serially on one CPU. So this is more
load-balancing than a real cluster. It should be quite easy to set up.
<li><a href=http://www.beowulf.org>Beowulf Cluster</a>: Requires GRASS
modifications not done yet.
<li>GRASS 5 contains the "gmath" library which contains wrapper functions to
the numerical libraries <a
href=http://www.netlib.org/lapack/>LAPACK</a>/<a
href=http://www.netlib.org/blas/>BLAS</a> which also exists in a
parallelized form <a
href=http://www.cs.utexas.edu/users/plapack/>PLAPACK</a> and <a
href=http://www.netlib.org/scalapack/pblas_qref.html>PBLAS</A> and <a
href=http://www.netlib.org/scalapack/>ScaLAPACK</a>. However, further
work has to be done to utilize the LAPACK/BLAS functions within GRASS.
