				<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>
