Updating phase 2 work of collective IO Description: When the size is bigger than some value for MPI derived data type, mpich 1.2.5 and lower version won't work any more, so in the configuration file, we will check the version number and switch from collective IO to independent IO by turning off complex derived datatype. Solution: Platforms tested: linux 2.4, AIX 5.1, Linux 2.4 IA64 and IRIX 6.5 Misc. update:
