Description:
The example code used to just run parallel I/O test in the current
directory which is most likely where the program is compiled.
In general, this directory is most likely not a parallel file system.
Therefore, the example code often fails.
Solution:
Add an option "-f <prefix>" for specifying the correct test files
pathname prefix. The program now requires an explicite file prefix
either via the "-f" option or the environment variable $HDF5_PARAPREFIX.
(With the proper setup of $HDF5_PARAPREFIX, the example code can run
automatically in situtaions such as batch job or gmake check.)
Also added feature to cleaup up the test files created.
Of course, an added option "-c" to turn OFF the cleanup action.
Platforms tested:
eirene, modi4, dangermouse (all parallel modes).
modi4 (serial) just to verify it can compile.
