Installation instructions for Parallel HDF5
-------------------------------------------
This file contains instructions for the installation of parallel HDF5 (PHDF5).
PHDF5 requires an MPI compiler with MPI-IO support and a parallel file system.
If you don't know yet, you should first consult with your system support staff
of information how to compile an MPI program, how to run an MPI application,
and how to access the parallel file system. There are sample MPI-IO C and
Fortran programs in the section of "Sample programs". You can use them to
run simple tests of your MPI compilers and the parallel file system.
If you still have difficulties installing PHDF5 in your system, please
In your mail, please include the output of "uname -a". If you have run the
"configure" command, attach the output of the command and the content of
2. Quick Instruction for known systems
--------------------------------------
The following shows particular steps to run the parallel HDF5
configure for a few machines we've tested. If your particular platform
is not shown or somehow the steps do not work for yours, please go
to the next section for more detailed explanations.
HDF5 knows several parallel compilers: mpicc, hcc, mpcc, mpcc_r.
To build parallel HDF5 with one of the above, just set CC as it
and configure. The "--enable-parallel" is optional in this case.
$ CC=/usr/local/mpi/bin/mpicc ./configure --prefix=<install-directory>
First of all, make sure your environment variables are set correctly
