MuQun Yang bee5c236e5 [svn-r11065] Purpose:
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:
2005-07-12 14:14:18 -05:00
