When configure with enable-paralle, H5detect and debug were not
compiled with $(LIBS) but were executed via RUNTEST (mpirun ...).
The O2K mpirun can't handle such an object code.
Solutions:
Compile them also with $(LIBS) which contains the mpi library names.
Could have just removed $(RUNTEST) but in some parallel system, all
object file may have to be launched by some mpirun-equivalent command
anyway.
Platforms tested: O2K
Added modification entry to H5F_open header. Should have been done
when i added the access template argument.
H5Fprivate.h:
The hardcode setting to "define MPIO as the default IO
when HAVE_PARALLEL is set" cause all test programs to fail since
none of them is coded with the needed MPI_Initialize. Change it
back to the previous setting of using sequential I/O allows user
to use sequential I/O by default and use MPIO only if he/she explicitely
asks for it via access template setting.
file does not exist, the code tried to open the file with EXCL CREATE.
ROMIO cannot handle file-open with EXCL Create due to racing problem.
The first process creates the file which then fails all
other processes.
Solution: In the parallel code, turn on TRUNC mode to allow "late" open
calls to succeed too. It is safe to force TRUNC mode since the file is
known non-existing at that point. The MPIO implementation has to
provide the real solution.
Platform tested: O2K with ROMIO.
while he is visiting LLNL. I changed the default creation template
offset and length to 4. Will fix the problem later.

alignment on the DEC alpha. Changed object header message
alignment to 8-bytes.

Fixed a few irix64 warnings regarding size_t vs. int,
variables set but not used, printf formats
./config/irix64
Added `-woff 1196' to get rid of errors about __vfork() being
implicitly defined in a system header file.
./src/H5B.c
Fixed a stack alignment problem.
h5_write.c - stores INT array as INT32 little endian dataset in the HDF5 file.
h5_read.c - gets info about the dataset;
reads hyperslab from the dataset in the file into
2-dim slice of the 3 dimensional array.
h5_compund.c - creates compound dataset and writes it to the file;
reads subsets of the dataset.
h5_extend_write.c - writes extendable dataset.
h5_extend_read.c - gets info about the dataset;
reads dataset and one of the chunks.
failures. Row back the offset and length sizes to 4 (instead of
sizeof(size_t)) for now to pass all tests. Will fix it later.
(Also changed the default create template in H5F.c).
not assign the decoded value back to n.
Solution: Removed temporary variable _n (don't see why it is needed.)
Use the variable n directly.
Platform tested: IRIX64 -64
----------------------
./src/H5H.c
Changed a temporary buffer from 20 bytes to 52 bytes.
./test/tfile.c
Default sizes for file addresses and sizes are the same as
sizeof(size_t) on the machine that creates the file.
The default file addr and size sizes for new files are the
same as sizeof(size_t) on the machine that creates the
file. They used to always be 4.
./src/H5Pprivate.h
./src/H5Psimp.c
Fixed `start' and `nelmts' arguments to be `size_t'.

./src/H5C.c
./src/H5Cprivate.h
./src/H5D.c
./src/H5Dpublic.h
Added H5Dget_create_parms(), trying to stay one step ahead of
Elena ;-)
----------------------
./MANIFEST
Added H5Fmpio.c. One way to check that you've properly
included new files is to run `./bin/release none', then unpack
the resulting tar file somewhere and try to compile it. The
tar file will be ./releases/hdf-5.0.0a.tar.
./config/freebsd2.2.1
./config/linux
Added `-ansi'
./acconfig.h
Added definitions for PHDF5 and HAVE_PARALLEL.
./configure.in
Added minimal support for parallel build. Kim and Albert will
have to flesh this out or I can do it if they're more specific
about what they need.
./config/commence.in
Added default value for $(RUNTEST)
./config/conclude.in
`make test' uses value of $(RUNTEST) to run test cases.
./src/Makefile.in
Added PARALLEL_SRC for conditional compilation of H5Fmpio.c
./src/H5D.c
./src/H5Dpublic.h
Added H5Dget_type() for Elena
NOTE: These changes require that configure be rerun. If you're using
GNU make it will happen automatically, otherwise do it by
hand.

Removed the unused file argument from H5P_modify.
Added H5P_extend().
