[svn-r11942] Purpose:
Add collective chunk IO supports Description: Added a macro hdf5_mpi_special_collective_io_works to filter out some mpi-io packages that don't support collective IO for no IO contributions in some processes. Solution: 1. "hdf5_mpi_special_collective_io_works=${hdf5_mpi_special_collective_io_works= 'no'}" has been added at the end of file ia64-linux-gnu and linux-gnulibc1 2. Some comments are added in ia64-linux-gnu and linux-gnulibc1. 3. Documents are added inside RELEASE.txt. Platforms tested: Parallel: IBM AIX 5.2(copper) Linux (heping) mpich-1.2.6 SDSC Teragrid mpich-1.2.5 Linux(Tungsten) mpich-1.2.6 Altix(NCSA cobalt) Seq: Linux(heping) Misc. update:
