+==============================================================================
+
++ 0. HDF5 library
+-----------------
+
+Make sure you have a working version of the HDF5 library installed. If you plan
+to use parallel I/O you need to use a parallel HDF5 version. Source files and
+installation instructions are available from the HDF5 website:
+
+http://www.hdfgroup.org/HDF5/
+
+
++ 1. Quick start (If you feel lucky...)
+----------------------------------------
+
+For many platforms, where compilers are installed in the "default" location
+and all the environment variables are set correctly, it should be sufficient 
+to type: 
+
+./configure [OPTIONS] && make [install]
+
+to have the libraries and test program compiled.
+
+
++ 2. Configure line options
+----------------------------
+
+To view a full list of configure option, use:
+
+./configure --help
+
+(1) Enable options
+--enable-fortran
+--enable-parallel
+--enable-tools
+--enable-python
+--enable-64 (only for AIX and Irix)
+
+(2) Setting compilers related variables manually
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE before running configure. For example, if you are using the bash
+shell, you might type:
+
+export CC=gcc
+
+to set the default C compiler. See below for descriptions of some useful
+variables.
+
+Compiler environment variables:
+  CC          C compiler command
+  CXX         C++ compiler command
+  FC          Fortran compiler command
+  MPICC       MPI-enabled C compiler command
+  MPICXX      MPI-enabled C++ compiler command
+  MPIFC       MPI-enabled Fortran compiler command
+  CFLAGS      flags to append when invoking the C compiler
+
+Library environment variables:
+  LDFLAGS     flags to append when invoking the linker
+
+(3) Setting prefix for installation manually (by default, the package will
+install itself in the 'build' subdirectory of your source directory)
+--prefix=PREFIX         install files in PREFIX
+
+
++ 3. Platform specific settings for compiling libraries & test programs
+------------------------------------------------------------------------
+
+Building
+        make  : builds the libraries and test programs
+	make install: builds and installs
+        make clean : removes extraneous object files
+        make distclean : returns configuration to unconfigured state

+FIRST THING FIRST!! Type:
+
+module load intel
+to have the proper compilers set up for use.
+
+module load hdf5_par
+
+[NOTE: module load hdf5 does not work at this moment. 
+Possible installation error of HDF5 on Davinci.]
+
+
+Brief profile:
+CC = icc
+CXX = icc
+FC = ifort
+MPICC = icc
+MPICXX = icc
+MPIFC = ifort
+
+If default doesn't work, try:
+
+For C shell: 
+env CC=icc CXX=icc FC=ifort MPICC=icc MPICXX=icc MPIFC=ifort ./configure && make install
+
+For Korn or Bourne shell:
+CC=icc CXX=icc FC=ifort MPICC=icc MPICXX=icc MPIFC=ifort ./configure && make install
+
+And, of course, you should add configure options, such as --enable-fortran --enable-parallel.
+
+

+
+For C shell: 
+env CC=icc CXX=icc FC=ifort MPICC=icc MPICXX=icc MPIFC=ifort ./configure --enable-fortran --enable-parallel && make install
+
+For Korn or Bourne shell:

+
+has functioned correctly.
+
+

+
+
+To run test program, go to test directory:
+
+(i) Serial test
+run:
+./H5testF
+./H5PartTest
+
+(ii) Parallel test
+In Jacquard, we need a script to run parallel programs, since Jacquard does not support interactive parallel processing. Instead, we need to submit the task to a queue. A sample script (run_H5testFpar.scr) may look like below:
+
++++++++++++++++++++++++++++++++++++++++
+#!/bin/csh
+#PBS -l nodes=1:ppn=2,walltime=00:05:00
+#PBS -N  H5testFpar
+#PBS -o H5testFpar.out
+#PBS -e H5testFpar.err
+#PBS -q debug
+#PBS -A mpccc
+#PBS -V
+
+setenv PBS_OWORKDIR /home/H5Part/test
+
+cd $PBS_O_WORKDIR
+mpirun -np 2 ./H5testFpar
++++++++++++++++++++++++++++++++++++++++
+
+Then, we need to submit the task to a queue by running:
+
+qsub run_H5testFpar.scr
+
+After processed, the result will appear in H5testFpar.out, and error messages will appear in H5testFpar.err.

++ 4. Trouble shooting (Things to check for...)
+--------------------------------------------
+(0) Have you set the LD_LIBRARY_PATH?
+---Some systems require the user to manually set the environment variable, LD_LIBRARY_PATH. To do so:
+
+set the environment variable HDF5ROOT or PHDF5ROOT to point to your installation of HDF5 (serial and/or parallel respectively).
+
+For Korn or Bourne shell:
+	LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${HDF5ROOT}/lib;export LD_LIBRARY_PATH
+	LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:{PHDF5ROOT}/lib;export LD_LIBRARY_PATH
+
+For C shell:
+	setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${HDF5ROOT}/lib
+	setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${PHDF5ROOT}/lib
+
+Note that the values of HDF5ROOT & PHDF5ROOT will be in the "summary" section when you run configure.
+
+Not properly set LD_LIBRARY_PATH value may result in a runtime error:
+
+./H5PartTest: error while loading shared libraries: libhdf5.so.0: cannot open shared object file: No such file or directory
+
+(1) Are the compilers set correctly? 
+---Check with: which COMPILER
+
+(2) Have you installed HDF5?
+---You can get it at: http://vis.lbl.gov/Research/AcceleratorSAPP/index.html
+
+(3) Have you loaded the proper modules? 
+---It is necessary in Davinci & Bassi, and configure && make install may not work without it.

-(ii) Parallel test
-In Jacquard, we need a script to run parallel programs, since Jacquard does not support interactive parallel processing. Instead, we need to submit the task to a queue. A sample script (run_H5testFpar.scr) may look like below:
-
-+++++++++++++++++++++++++++++++++++++++
-#!/bin/csh
-#PBS -l nodes=1:ppn=2,walltime=00:05:00
-#PBS -N  H5testFpar
-#PBS -o H5testFpar.out
-#PBS -e H5testFpar.err
-#PBS -q debug
-#PBS -A mpccc
-#PBS -V
-
-setenv PBS_OWORKDIR /home/H5Part/test
-
-cd $PBS_O_WORKDIR
-mpirun -np 2 ./H5testFpar
-+++++++++++++++++++++++++++++++++++++++
-
-Then, we need to submit the task to a queue by running:
-
-qsub run_H5testFpar.scr
-
-After processed, the result will appear in H5testFpar.out, and error messages will appear in H5testFpar.err.

-+ 4. Trouble shooting (Things to check for...)
---------------------------------------------
-(0) Have you set the LD_LIBRARY_PATH?
----Some systems require the user to manually set the environment variable, LD_LIBRARY_PATH. To do so:
-
-set the environment variable HDF5ROOT or PHDF5ROOT to point to your installation of HDF5 (serial and/or parallel respectively).
-
-For Korn or Bourne shell:
-	LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${HDF5ROOT}/lib;export LD_LIBRARY_PATH
-	LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:{PHDF5ROOT}/lib;export LD_LIBRARY_PATH
-
-For C shell:
-	setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${HDF5ROOT}/lib
-	setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${PHDF5ROOT}/lib
-
-Note that the values of HDF5ROOT & PHDF5ROOT will be in the "summary" section when you run configure.
-
-Not properly set LD_LIBRARY_PATH value may result in a runtime error:
-
-./H5PartTest: error while loading shared libraries: libhdf5.so.0: cannot open shared object file: No such file or directory
-
-(1) Are the compilers set correctly? 
----Check with: which COMPILER
-
-(2) Have you installed HDF5?
----You can get it at: http://vis.lbl.gov/Research/AcceleratorSAPP/index.html
-
-(3) Have you loaded the proper modules? 
----It is necessary in Davinci & Bassi, and configure && make install may not work without it.

+For more information on using the H5Part API, see the H5Part website:
+
+        http://www-vis.lbl.gov/Research/AcceleratorSAPP/
+
+
+Motivation
+----------
+
+Particle based simulations of accelerator beam-lines, especially in six
+dimensional phase space, generate vast amounts of data. Even though a subset
+of statistical information regarding phase space or analysis needs to be
+preserved, reading and writing such enormous restart files on massively
+parallel supercomputing systems remains challenging.
+
+H5Part is a very simple data storage schema and provides an API that
+simplifies the reading/writing of the data to the HDF5 file format. An
+important foundation for a stable visualization and data analysis environment
+is a stable and portable file storage format and its associated APIs. The
+presence of a "common file storage format," including associated APIs, will
+help foster a fundamental level of interoperability across the project's
+software infrastructure. It will also help ensure that key data analysis
+capabilities are present during the earliest phases of the software development
+effort.
+
+H5Part is built on top of the HDF5 (Hierarchical Data Format) library. HDF5
+offers a self-describing machine-independent binary file format that supports
+scalable parallel I/O performance for MPI codes on a variety of supercomputing
+systems, and works equally well on laptop computers. The API is available for
+C, C++, and Fortran codes. The H5Part file format and APIs enable disparate
+research groups with different simulation implementations to transparently
+share datasets and data analysis tools. For instance, the common file format
+will enable groups that depend on completely different simulation
+implementations to share data analysis tools.
+
+
+File Organization and API
+-------------------------
+
+The proposed file storage format uses HDF5 for the lowlevel file storage and a
+simple API to provide a high-level interface to that file format. A programmer
+can either use the H5Part API to access the data files or write directly to the
+file format using some simple conventions for organizing and naming the objects
+stored in the file.
+
+In order to store Particle Data in the HDF5 file format, we have formalized the
+hierarchical arrangement of the datasets and naming conventions for the groups
+and associated datasets. The sample H5Part API formally encodes these
+conventions in order to provide a simple and uniform way to access these files
+from C, C++, and Fortran codes. The API makes it easier to write very portable
+data adaptors for visualization tools in order to expand the number of tools
+available to access the data. Even so, anyone can use the HDF5 h5ls utility to
+examine the organization of the H5Part files and even write their own
+HDF5-based interface for reading and writing the file format. The standards
+offered by the sample API are completely independent of the standard for
+organizing data within the file.The file format supports the storage of
+multiple timesteps of datasets that contain multiple fields.

+
+  Write array of 32 bit floating point data to file.
+
+  After setting the number of particles with \c H5PartSetNumParticles() and
+  the current timestep using \c H5PartSetStep(), you can start writing datasets
+  into the file. Each dataset has a name associated with it (chosen by the
+  user) in order to facilitate later retrieval. The name of the dataset is
+  specified in the parameter \c name, which must be a null-terminated string.
+
+  There are no restrictions on naming of datasets, but it is useful to arrive
+  at some common naming convention when sharing data with other groups.
+
+  The writing routines also implicitly store the datatype of the array so that
+  the array can be reconstructed properly on other systems with incompatible
+  type representations.
+
+  All data that is written after setting the timestep is associated with that
+  timestep. While the number of particles can change for each timestep, you
+  cannot change the number of particles in the middle of a given timestep.
+
+  The data is committed to disk before the routine returns.
+
