[svn-r6998] Purpose:
"Bug fix"
Description:
This version is showing very slow HDF5 I/O write speeds (about 40%
of MPIO). It was because the library is writing fill values by
default. There is a no-fill option which set to FALSE. Changed
it to TRUE since MPIO and POSIX are not doing fill values.
This is just a stop gap fix since the better fix would be to
change the library to not write fill-values in this case.
Platforms tested:
modi4 parallel and LANL Q paralllel.
No h5committest test because it is very trivia.
Misc. update:
