a0cec096995Purpose:
Bug fix
Description:
compilers on some platforms complain about printf being declared implicity.
Solution:
printf is defined in stdio.h. #include'd it.
Platforms tested:
heping and MCR
Misc. update:

2bfc74c743dPurpose:
Bug Fix
Description:
mpich 1.2.4 does not properly implement the MPI_STATUS_IGNORE argument. It is treated as a NULL and this causes
some functions to segfault when they attempt to write status information to this NULL address.
Solution:
Replaced the MPI_STATUS_IGNORE arguments with an MPI_Status variable into which status information can be safely written.
Platforms tested:
eirene (mpich 1.2.4, this bug has been fixed in mpich 1.2.6).

b5d91995549Purpose:
Add derived data type test.
Description:
Solution:
Platforms tested:
Misc. update:
485d1a81229Fixed it to use the INCLUDE instead of USE statement because that is
what HDF5 test examples use. Also change the filename to create file
in the local directory instead of /tmp.

f80003e1581Purpose:
Initial version
Description:
MPI-IO Test: One writes, Many reads.
Verify if only one process writes some data and then all other
processes can read them back correctly. This tests if the
underlaying parallel I/O and file system supports parallel I/O
correctly.
Platforms tested:
Teragrid-NCSA.

32e064dcb93Description:
The initial version did not have any unique F90 feature.
Any F77 compiler could have compiled it fine.
Added real F90 feature.
Platforms tested:
Just tested by the pgf90 compiler in Eirene.
Albert Cheng
40e777f7ed9Added a Sample PHDF5 Fortran program.
Copied from the Tutorial example.
Platforms tested:
Test compiled it once in Teragrid.
Albert Cheng
688cf940e2dPurpose:
Fixing some syntax warning
Description:
Replace TAB with spaces just to pacify some compilers from
whinning about it.
Platforms tested:
Tested in TG-NCSA where the f90 whinned about it.
Albert Cheng
92900985132Purpose:
changed the default filename to be in the local directory.
Platforms tested:
modi4 and eirene.
Albert Cheng
4fc9d0c4959Purpose:
new features.
Description:
added writing data, reading them back and verify correctness.
Platforms tested:
Eirene.
Albert Cheng
62716bc4d0ePurpose:
Bug fix
Description:
Sample_mpi.c: has an unnecessary MPI_File declaration.
Sample_mpio.c: should #incldue <mpio.h> if needed.
Platforms tested:
Tflops which has a little more picky MPI implementation that
exposed the above problems.
Albert Cheng
bc7ae3a3778Purpose:
New HDF4 C and F77 sample programs. Copied from the
HDF4 Tutorial.
Platforms tested:
Copper (the new IBM p690 machine).
Albert Cheng
da58042a216Added printing of hostname to see where processes are run.
Added more comments too.
Albert Cheng
61d1fd76706Got rid of unused filename variable. Added comments about doing hostname.
Albert Cheng
e8a7d195bf6Description:
Added some messages saying what it attempts to do and report
it succeeded or failed.
Platforms tested:
eirene and modi4

to do performance testing...

5eecc703129This is a little gem that Quincey passed to me. It figures out
all those machine characteristics in data representations--sizes
of int, float; floating number representations; endianess;...
Very useful when you try to port HDF software to a new machine.

f70c53e4455This contains simple example programs. They usually invoke only the
basic features standard in their corresponding language or library.
They can be used to test if the compiler or library is working
properly.
For example, a fortran 77 compiler will not be able to compile th
Sample_f.f90 program but a fortran 90 compiler should.
Likewise, an MPI library without MPI-IO support, can compile
the Sample_mpi.c correctly but not the Sample_mpio.c program.
