[svn-r11788] Purpose:
Patch.
Description:
Copper would fail with a message of
0032-113 Out of memory in routine unknown, task 0
when run with 3 processes and size 1MB in MPI-IO tests.
It seems to be a copper MPIO error.
Solution:
Reduced the upper bound of default write size to 1/2MB (but
tests only go to 1/4MB) for now, pending permenant fix from
Copper.
Platforms tested:
Copper.
