1. In H5Dwrite and H5Dread, let the data buffer point to a fake address if the application passes
in an empty buffer. This is mainly for MPIO programs that some processes may not have any
data to write or read but still participate the I/O. This solution solves some MPI's problem
like the ChaMPIon on tungsten which doesn't support empty buffer.
2. The ChaMPIon on tungsten doesn't support complex derived MPI data type correctly and collective
I/O when some processes don't have any data to write or read correctly. Detect the compiler
"cmpicc" in the system-specific config file and set the variables for these two cases to false.
The PHDF5 library already has set up a way to switch collective chunked I/O to independent
under these two cases.
3. A bug fix - During the work of the optimization for compound data I/O, the case for switching
collective chunked I/O to independent I/O was leftout. Fixed it by adding I/O caching to it in
H5D_multi_chunk_collective_io in H5Dmpio.c.
Tested on tungsten, cobalt, and kagiso for parallel; on linew and smirom for serial.

HDF5 version 1.8.0-beta3post1 currently under development
Please refer to the release_docs/INSTALL file for installation instructions.
------------------------------------------------------------------------------
This release is almost fully functional for the entire API defined in the
documentation, see the RELEASE.txt file in the release_docs directory for information
specific to this release of the library. The INSTALL file contains
instructions on compiling and installing the library. The INSTALL_parallel
file contains instructions on installing the parallel version of the
library. The INSTALL* files can be found in the release_docs/ directory.
Documentation for this release can be found at the following URL:
http://hdfgroup.org/HDF5/release/alpha/obtain518.html
Four mailing lists are currently set up for use with the HDF5
library.
news - For announcements of HDF5 related developments,
not a discussion list.
hdf-forum - For general discussion of the HDF5 library with
other users.
hdf5dev - For discussion of the HDF5 library development
with developers and other interested parties.
To subscribe to a list, send mail to "<list>-subscribe@hdfgroup.org".
where <list> is the name of the list.
E.g., mail hdf5-subscribe@hdfgroup.org
Messages to be sent to the list should be sent to "<list>@hdfgroup.org".
Periodic code snapshots are provided at the following URL:
ftp://ftp.hdfgroup.uiuc.edu/pub/outgoing/hdf5/snapshots
Please read the README.txt file in that directory before working with a library
snapshot.
The HDF5 website is located at http://hdfgroup.org/HDF5/
Bugs should be reported to help@hdfgroup.org.
