[svn-r11951] Purpose:
Enhance collective chunk IO supports Description: Add a new test to check the correctness of the HDF5 library behavior for collective IO mode when one process doesn't have any contribution for IO. Solution: Platforms tested: IBM AIX 5.2(copper) Linux (heping) mpich-1.2.6 Misc. update:
