+<h4>Building Parallel HDF5</h4>
+<P>
+When you build HDF5, you will need to build an version with parallel I/O
+enabled. Here is a set of configure options that worked for us on a
+Linux workstation running SuSE 10.1 with MPICH installed in /usr/local/mpich.
+</p>
+
+<pre>
+./configure --prefix=/usr/local/hdf5-mpich --enable-parallel CC=mpicc CXX=mpicxx --disable-shared --enable-static --enable-stream-vfd
+</pre>
+
+<UL>
+<li> --prefix=/usr/local/hdf5-mpich : the location where the HDF5 libs and
+binaries will be installed.</LI>
+<li> --enable-parallel : contrary to the HDF5 documentation, which says that
+"--enable-parallel" is optional for building the parallel version of
+HDF5, you <b>must</b> have --enable-parallel to get the parallel-enabled
+build. See <a href="ftp://ftp.hdfgroup.org/HDF5/current/src/unpacked/release_docs/INSTALL_parallel">these notes from HDF5</a> where they claim that
+--enable-parallel is optional.</LI>
+<li> CC=mpicc CXX=mpicxx : contrary to the output from configure --help, the
+configure script seems to ignore the CC and CXX environment variables.
+We tried setting these environment variables to mpicc and mpicxx,
+respectively, and then ran configure with --enable-parallel. The configure
+script would faile with this error message: 	
+<pre>
+checking whether a simple MPI-IO program can be linked... no
+configure: error: unable to link a simple MPI-IO application
+</pre>
+</LI>
+<LI> --disable-shared and --enable-static: the HDF5 build failed for us
+w/o these options when attempting to read symbols from libmpich.a. The
+result of these options is that your parallel-enabled HDF5 libaries
+will be static rather than dynamic.
+
+</UL>
