Installation instructions for Parallel HDF5
-------------------------------------------
1. Overview
-----------
This file contains instructions for the installation of parallel
HDF5. Platforms supported by this release are SGI Origin 2000, IBM SP2,
Intel TFLOPs, and Linux version 2.4 and greater. The steps are kind of
unnatural and will be more automized in the next release. If you have
difficulties installing the software in your system, please send mail to
hdfparallel@ncsa.uiuc.edu
In your mail, please include the output of "uname -a". Also attach the
content of "config.log" if you ran the "configure" command.
First, you must obtain and unpack the HDF5 source as described in the
INSTALL file. You also need to obtain the information of the include and
library paths of MPI and MPIO software installed in your system since the
parallel HDF5 library uses them for parallel I/O access.
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.
------
TFLOPS
------
Follow the instuctions in INSTALL_TFLOPS.
-------
IBM SP2
-------
First of all, make sure your environment variables are set correctly
to compile and execute a single process mpi applications for the SP2
machine. They should be similar to the following:
setenv CC mpcc_r
setenv MP_PROCS 1
setenv MP_NODES 1
setenv MP_LABELIO no
setenv MP_RMPOOL 0
setenv RUNPARALLEL "MP_PROCS=2 MP_TASKS_PER_NODE=2 poe"
setenv LLNL_COMPILE_SINGLE_THREADED TRUE
The shared library configuration for this version is broken. So, only
static library is supported.
An error for powerpc-ibm-aix4.3.2.0's (LLNL Blue) install method was
discovered after the code freeze. You need to remove the following line
from config/powerpc-ibm-aix4.3.2.0 before configuration:
ac_cv_path_install=${ac_cv_path_install='cp -r'}
Then do the following steps:
$ ./configure --disable-shared --prefix=<install-directory>
$ make # build the library
$ make check # verify the correctness
$ make install
---------------
SGI Origin 2000
Cray T3E
(where MPI-IO is part of system MPI library such as mpt 1.3)
---------------
#!/bin/sh
RUNPARALLEL="mpirun -np 3"
export RUNPARALLEL
LIBS="-lmpi"
export LIBS
./configure --enable-parallel --disable-shared --prefix=$PWD/installdir
make
make check
make install
---------------
SGI Origin 2000
Cray T3E
(where MPI-IO is not part of system MPI library or I want to use my own
version of MPIO)
---------------
mpi1_inc="" #mpi-1 include
mpi1_lib="" #mpi-1 library
mpio_inc=-I$HOME/ROMIO/include #mpio include
mpio_lib="-L$HOME/ROMIO/lib/IRIX64" #mpio library
MPI_INC="$mpio_inc $mpi1_inc"
MPI_LIB="$mpio_lib $mpi1_lib"
#for version 1.1
CPPFLAGS=$MPI_INC
export CPPFLAGS
LDFLAGS=$MPI_LIB
export LDFLAGS
RUNPARALLEL="mpirun -np 3"
export RUNPARALLEL
LIBS="-lmpio -lmpi"
export LIBS
./configure --enable-parallel --disable-shared --prefix=$PWD/installdir
make
make check
make install
---------------
Linux 2.4 and greater
---------------
Be sure that your installation of MPICH was configured with the following
configuration command-line option:
-cflags="-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64"
This allows for >2GB sized files on Linux systems and is only available
with Linux kernels 2.4 and greater.
3. Detail explanation
---------------------
The HDF5 library can be configured to use MPI and MPI-IO for parallelism
on a distributed multi-processor system. The easiest way to do this is to
have a properly installed parallel compiler (e.g., MPICH's mpicc or IBM's
mpcc) and supply that executable as the value of the CC environment
variable:
$ CC=mpcc ./configure
$ CC=/usr/local/mpi/bin/mpicc ./configure
If no such wrapper script is available then you must specify your normal
C compiler along with the distribution of MPI/MPI-IO which is to be used
(values other than `mpich' will be added at a later date):
$ ./configure --enable-parallel=mpich
If the MPI/MPI-IO include files and/or libraries cannot be found by the
compiler then their directories must be given as arguments to CPPFLAGS
and/or LDFLAGS:
$ CPPFLAGS=-I/usr/local/mpi/include \
LDFLAGS=-L/usr/local/mpi/lib/LINUX/ch_p4 \
./configure --enable-parallel=mpich
If a parallel library is being built then configure attempts to determine
how to run a parallel application on one processor and on many
processors. If the compiler is `mpicc' and the user hasn't specified
values for RUNSERIAL and RUNPARALLEL then configure chooses `mpirun' from
the same directory as `mpicc':
RUNSERIAL: /usr/local/mpi/bin/mpirun -np 1
RUNPARALLEL: /usr/local/mpi/bin/mpirun -np $${NPROCS:=3}
The `$${NPROCS:=3}' will be substituted with the value of the NPROCS
environment variable at the time `make check' is run (or the value 3).
