[svn-r11469] Purpose:
Fix the collective chunk IO bug when MPI complicated derived datatype is not working.
Description:
Suspected it was an MPI-IO bug at mcr with mpich 1.2.4.
The current implementation had no optimization for collective IO after discussing with Albert. So I decided to switch collective IO to independent IO when we found MPI complicated derived datatype not working.
Solution:
Platforms tested:
heping mpich 1.2.6
tera-grid mpich 1.2.5
(shouldn't affect platforms which the complicated derived datatype is working, so no
need to test three platforms.)
