<h2>Downloading HDF5</h2></a>
|
|
You will need to download and install the hdf5 library and link H5Part with it.
|
|
<pre>
|
|
ftp ftp.ncsa.uiuc.edu

cd HDF/HDF5/current/src
|
|
ls
|
|
get hdf5-1.6.5.tar.gz (get the current version, this as the one on April 20th, 2006)
|
|
cd szip/src
|
|
ls
|
|
get szip-2.0.tar.gz (get the current version, this as the one on April 20th, 2006)
|
|
cd ../../
|
|
cd zlib/1.2/src
|
|
ls
|
|
get zlib-1.2.1.tar.gz (get the current version, this as the one on April 20th, 2006)

Note: you might already have libz in your system and you will not need libsz unless you build hdf5 with support for it.

<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.
